Maybe it's already being sold as a rebadge.
Siglent are the OEM for many brands....LeCroy, BK, RS........

Tonight I’ve checked siglent.eu and saw SPE1168X listed for about 2 hundred something Euro, IIRC. Went out for a few beers and when I came back to check it it disappeared. At least  there’s already user manual available at  https://www.batronix.com/files/Siglent/Labornetzteile/SPD1000X/SPD1168X-UserManual-EN.pdf

Still 10mV/10mA accuracy so they might have left the extra digits out. Voltage: ±(0.03% of reading+10 mV) Current: ±(0. 3% of reading+10 mA)  :palm:
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

The sense terminals are a nice feature.  Too bad they couldn't have squeezed these power supplies into a stackable form factor like the DMMs/AWGs.

Assuming they use "accuracy" and "resolution" somewhat correctly (although, as our lecturer used to say, it is never "accuracy" but "inaccuracy"), then the last digits still have their uses, e.g. to detect a small changes in them. Whether such was e.g. really from 1.234A to 1.235A or from 1.244A to 1.245A might in many cases be less important.  Of course, they have not specified how the inaccuracy behaves, but typically the shown values are still monotonic and linear enough.

(Otherwise most of the 7-8 digit multimeters could leave out 1-2 last digits, too, since most of them are "only" specified to be accurate to 6 digits, or 5 digits after a year.)

Some quick facts/findings from the first I've seen of these:

2s boot time.
Quiet smart fan. 80mm. At no time with the following tests and loads did the fan speed increase.
2 sets of 650mm leads with croc clips, one set with open lug terminals and the other with molded banana plugs.
Output enable soft key driving an output relay. Note, the relay is only bought into ON switching function at voltages above 4.4V settings below which silicon is doing the switching.
19mm terminal spacing.


Overshoot test, high current.
12V set, 8A set.
12V halogen auto lamp, 5A draw.

DSO SDS1104X-E, 10x stock probe, Normal triggering.



Ripple check.
Load as above.


-------------------------------------------------------------------------------------------

Overshoot test, low current.
4.4V set, 8A set
Red LED with 1k current limit resistor.
5mA displayed as drawn.



Ripple check.
Load as above.




More checks and tests later.

Is the spacing between de banana terminals the regular 19mm or still 20mm like the other Siglent units ?

Has anyone tried to download and install EasyPower - 1.01.01.16 (Release Date 07.18.18 )?

When I get the the installer start-up screen, it looks like it might be the Chinese version.  The download from Siglent and Siglent America both do this.  I went through the installer anyway, and it seemed to install an English version!  However, upon execution and connection to a device, the app shrinks down to just its menu for a second then disappears.

I uninstalled it, and tried to go back to 1.01.01.13 and it now does the same thing.  The installation has also messed up EasyWave.  All sorts of unsupported operation dialogs appear during its execution, and then when connecting to a device it shows an invalid pointer dialog, then just displays the screen attached.  EasyDMM, EasyScope, and EasySpectrum seem unaffected.

I wanted to upgrade to the .16 version of EasyPower as .13 isn't compatible with the SPD1168X.  Another problem with .13 (or it might be with the SPDs themselves) is that static IPs don't work.  They can be assigned but EasyPower doesn't see them.

Completely uninstalling the EasyPower and EasyWave using the Windows Control Panel, and re-installing EasyWave and EasyPower .13 fixed it.  However, there is definitely something not right about that .16 version of EasyPower. 

Windows 10 Pro v1803

Once past the installer it's all English UI.

Installed and tested.  Installer is in English and all functions work with the SPD1168X.

Has anyone else noticed the static IP issue?  All other equipment I have works fine using a static IP, but both the SPD3303X-E and this SPD1168X do not.

Thanks Bill, I'll shoot that through to Siglent.
Defpom is to have a look at the EasyPower SW soon so maybe he'll document this in a vid so Siglent can plainly see the issue.

The FW refers to 2 models:

SPD1168X
SPD1168X-C

What are their differences?

The 'C' is the Chinese only version with lower 10 mV/mA resolution.

Interestingly there's another model now on the Chinese website, SPD1305X also a single channel unit with remote sense but with 30V 5A 1 mV/mA outputs.

For me it was important information but I did not find it. Well, in the 30V version, the integrated circuits responsible for setting and reading the voltage and current are AD7782 and DAC8562. Unfortunately, I have no information on how to calibrate this power supply in the future...

They are a closed box calibration, in that PC scripts and a universal calibrator are needed to program the PSU's internal calibration settings.
More info on this matter is available here:

So I will wait for service manual ... I think that the calibration will not be particularly difficult. Probably like in other devices, i.e. based on two voltage and current points. Possibly, there may be a zero offset.

It would be nice if they enumerated the bugs they actually fixed in the release notes rather than just "fixed some bugs".  I haven't noticed any buggy behavior on my SPD1168X's really, but I guess I'll update them anyway.   :-//

Update performed, no problems.

I have a problem with the update. I am getting the message "This file is not upgrade file". Firmware downloaded from Siglent. Any ideas what could be wrong? Maybe because I have FW version 2.01.01.07R1? The power supply shows the upgrade mode via USB but the progress indicator does (on LCD/TFT) not move and the "EasyPower" program gives the message as above.

diodak,

Do you have an SPD1168X or SPD1305X?  I just upgraded another SPD1168X successfully, however, both were via LAN and not USB.  The last one had FW v2.01.01.05R1.

Do you have the latest version of EasyPower?  I know that there was an update to the application to support these new supplies?  I am running version V100R001B01D01P16.

I have SPD1305X and I tried to update it via USB. EasyPower is the newest available. In that case, I will try via LAN (I did not know it would be possible - they recommend in PDF to make an update via USB). By the way - EasyPower does not fully support SPD1305X - you can not set a current greater than 3A ...

I'm sorry I don't have an SPD1305X.  I've performed all my updates to my Siglent supplies by LAN and have never had a problem.

That's strange regarding the current limit via EasyPower, IIRC it supports the full 8A for the 1168X.  Does EasyPower disable the second channel UI and provide the sense control UI when you are attached to the 1305X?

Updating via LAN also does not work. The same problem with the file error ... I guess simply this version of EasyPower does not work with SPD1305X.

The menu displayed in the GUI is unchanged, you can see both channels. When you give limit on 4A, the current will be set to 3.2 A. Also, 4-wire mode can not be set. What is interesting is whether via LAN or USB connection, makes the SPD1305X 5 beeps. I have no idea what these repeated beep mean.

When I first got the SPD1168X, the older version of EasyPower treated it somewhat like the SPD3303X-E.  The newer version added the sense control, disabled the second channel UI, and allowed for the proper current range.

It sure does seem like EasyPower is doing the same thing with your SPD1305X.

IIRC, the beeps mean the power supply received a command it didn't recognize or like; another reason to suspect Easypower is sending it SPD3303X commands.

There is some unsystematic in what Siglent does because the device control software appears much later than the device itself. It should go hand in hand. The more so if the software also has the function of updating the firmware. It remains to wait for the new version.

Yes, I think the EasyTools suite, and probably all PC-based control applications,are losing out to built-in webservers.  Most of the EasyTools applications look like they haven't been substantially modified in a decade or more.   

At least they've done a good job at providing the SCPI interface.

Yep, all this ^^^
Dunno what Siglent were thinking.........release new firmware and the EasyPower SW that's supposed to work with SPD1305X won't and you can't install any firmware that might fix it !  :wtf:  :horse:

I do not know what to say ... Thank you.
I confirm, now everything works, the new firmware has been uploaded correctly via the LAN. 1 channel works, you can set 5A. There is no warning signal (5 beep repeated by the SPD).

This week I got a Siglent SPD1305X - hardware version V1.0 - cal date 26th of October 2018. It is my first proper adjustable bench power supply with current limiting and I like it a lot.

It looks like a proper piece of gear with nice quality plastics. The user interface of the device itself seems pretty intuitive to me and very easy to use. The rotary control works well - it is easy to turn it to the value you want without it skipping numbers or anything annoying. I really like the 4 wire setup - it works well. Voltage readback on the device measures very close to my multimeter.

The binding posts work well with all my unshrouded banana plugs, even with the knobs undone as far as they will unscrew. Not loosey goosey. Probemaster stackable banana plugs work well as an example.

It is audibly pretty quiet with low fan noise. I also have a Siglent SDS1104X-E oscilloscope which I also find to have low fan noise, and the SPD1305X is maybe a little quieter than that.

I had no problem installing the suggested ancient version of NI-VISA runtime, and the EasyPower 1.01.01.18 software in a windows 10 virtual machine. Shame it requires windows. I updated the firmware over ethernet without issue. EasyPower is ok but a bit clunky. Slightly annoying that you have to type in an IP address to connect to a network device each time. It does not seem to remember the IP after disconnecting and it does not seem to let you use a hostname instead.

I tried measuring electrical ripple and noise using a 1X probe and thought I was seeing about 8mV peak to peak and <1V RMS - with or without a load (56 Ohm 5 watt resistor), but then I tested measuring an alkaline AA battery and it looked exactly the same. So I can't really measure electrical noise this low properly (no 50 Ohm attachments, lack of technique). I have no doubt the constant voltage electrical noise meets its specs and is very quiet.

Measuring voltage of the output while turning on the main power (clunking switch) showed some transients. Keep in mind I am a beginner and may be measuring or interpreting it wrong. Don't know if the transients are real or picked up from the environment. They seem pretty small and harmless anyway.


image: main power (clunking switch) transients

Using the soft channel on button, I did not measure any voltage overshoot. It looked very well behaved in that sense.

I thought I would try measuring current overshoot. Tests done with a Keysight U1272A multimeter with "Peak detection of up to 250 μs".

Testing done with U1272A set to measure current in the 10A range (which seems to be a 30A range as it is a 30,000 count meter) rather than autorange. Then Peak detect enabled.

Test A SPD1305X settings:
3.000V
0.020A
SPD1305X connected direct (pretty much a short) to current measurement on multimeter, then power on the channel with the soft power button.

Result: Usually about 16.8A peak. Yes that is Amps. Sometimes 0.023A which I think means the peak measurement was missed due to current spike being very short, and the limitations on very short duration peak measurement with multimeters. I guess this is a capacitor discharging?




Test B SPD1305X settings:
3.000V
0.020A
SPD1305X powered on circuit open, then short the outputs and unshort/open, then connect to current measurement on multimeter. Basically trying to see if connecting after turn on reduces the initial current.

Result: overload - so more than 30A. Probably due to a spark?




Test C SPD1305X settings:
3.000V
0.020A
SPD1305X
SPD1305X connected to current measurement on multimeter with a green LED inline (in series), then power on the channel with the soft power button. Testing to see how this relates to a more real world scenario.

Result: LED lights up yellow for fraction of a second then changes to green constantly lit. It is a standard green LED which should not be yellow so I assume this is from too much current. note - see Update4 below.
peak current measurement about 0.160A.




Test D SPD1305X settings:
5.000V
0.020A
SPD1305X
SPD1305X connected to current measurement on multimeter with a green LED inline (in series), then power on the channel with the soft power button.

Result: LED lights up for a fraction of a second then burnt out / open LED. Repeatable result with a second (initially good) LED. note - see Update4 below
Peak current measurement about 3.145A



Test D SPD1305X settings:
5.000V
0.020A
SPD1305X connected direct (pretty much a short) to current measurement on multimeter, then power on the channel with the soft power button.

Result: about 20A peak


If I am testing wrong you are welcome to educate me.


So I am a bit of a electronics beginner and I don't know if it is typical for currently limiting to not work on initial turn on or if this is only a problem with certain power supplies. Maybe a trap for young players? But anyway I don't think this SPD1305X can be relied on to limit initial current with soft power on for delicate loads, or with connecting delicate loads after soft power on. Perhaps delicate loads should have a current limiting resistor installed as an extra precaution. This might be common knowledge - I don't know. At least I did not blow up the expensive 10A fuse in my multimeter.

I was really hoping/assuming that the current limiting would work 100% of the time but I don't know if that is realistic. Perhaps they have a capacitor connected after the current limiting so there is no way to limit that? Is that a typical arrangement? Probably is to ensure low ripple. Does the SPD1305X have too much capacitance after the current limiting? Probably a balancing act.

For now I will assume this is all normal for power supplies unless someone can advise if it is not. Overall I am still happy with this power supply.



Update: current overshoot seems to be normal and is a trap for young players http://powersupply.blogs.keysight.com/2012/07/why-does-my-power-supply-overshoot-at.html


Update2: It seems that power supplies can be designed to minimise voltage overshoot (voltage-priority mode) or to minimise current overshoot (current-priority mode). https://www.electronicdesign.com/power/getting-your-priorities-straight-managing-overshoots

Perhaps with Siglent optimising this power supply to minimise voltage overshoot, that might have compromised current overshoot. It could be argued that this is our (EEVBlog members) fault for complaining about voltage overshoot on power supplies all the time. Siglent is just giving us what we asked for.

Update3: learnt how to display the image inline with the text.

Update4: I have made a mistake testing the LEDs with too high voltage. I did mention I was an electronics beginner. So that could be the reason why they burned out rather than too much current. Or it could have been both. I don't think this invalidates the current measurements I took. I think better measurements are needed with a current probe (I don't have one) and oscilloscope to try and determine if the energy contained in the current surge (amps and duration) is significant.

Dunno what you're doing plurn ?  :-//

You've seen my power ON screenshots for SPD1168X so because I haven't scoped a SPD1305X I'd thought I'd better after reading your post above.

Setting 24V 5A
Load 5W 24V auto bulb = 170mA (read from SPD display)


Power ON (output ON)



Like the SPD1168X, the ripple is so low it's very difficult to identify. Here our mains is 50 Hz so we're looking for 100 Hz ripple...........damned if I can find it. The spec is max 350 uVrms for ripple and noise and with Averaging we can reduce noise but good luck finding any ripple.

Further to a PM from plurn let's look at power ON not output ON.
This is with the same PSU settings as previously, 24V into a 5W bulb.

SPD1305X


Is it real, or is it induced into the OFF PSU output or some RFI/EMI from the mains switch inrush of magnetizing current into SPD1305X transformer ? Load lead length (acting as antenna) could have an impact on how large this spike could be.
Intuition tells me it's induced from the mains power switch and the DSO timebase setting would indicate this also.

Some more checks with a current shunt or current probe might be of use for further and deeper understanding.

Hello, I know this is an old thread but I am a beginner and I was considering the SPD1305X for my first bench power supply. From what it looks like it was determined that this supply doesn't have any significant voltage overshoot, is that correct? Near the end of the thread I couldn't tell if that was the final verdict, thanks.
Welcome to the forum.

Yes they are well behaved.

To add to some screenshots earlier in the thread, 2 more but with the output loaded with just a 10x probe.
SPD1305X Version 2.1.1.8 firmware (2019-04-29)
Power ON and output OFF (default)



Channel ON set to 5V 5A

Does the SPD1168X have programmable over-voltage and programmable over-current protection/cutout? I'm reading the user manual for it, and it doesn't mention it as far as I can see. This is a feature my QL355P has, so I'm comparing that to candidates for a 2nd supply.

Not programmable AFAIK only a set point for reverse OV that is specified as 22V+2V for SPD1168X.

EasyPower gave me an "Invalid update" message with the update. Re-applied v2.1.1.8 as a test, then v2.1.1.9 updated as expected.

Nice to have an OCP option when needed, I was thinking about missing that feature a few weeks ago. Being firmware driven, CC Mode kicks in well before OCP triggers in about 300ms. Both CC and OCP settings remain active at their set points. Worked well to protect a simple Red LED under reasonable conditions.

Nothing common with SPD5000 series commands.

For SPD1168X you can set/get voltage/current with fully formatted string e.g.:

ch1:volt 5.000
ch1:volt?
5.000

ch1:curr 0.5
ch1:curr?
0.5


but you cannot set/get ocp in this way, no ch1:ocp 2.345 will be accepted.

But!!!
you can just set/get voltage/current/ocp via simplest format! :

volt 4.534
volt?
4.534

curr 0.6
curr?
0.6

ocp 2.0
ocp?
2.0

*idn?
Siglent Technologies,SPD1168X,SPD13DCD7R1985,2.1.2.11,V2.0


As you can see, I have SPD1168X with HW version 2.0 and fw version 2.1.2.11

I still have a question about SPD1168X. I have siglent 4 devices (SDS2104X+, SPD1168X, SDG2042X, SDM3055). Everything is connected to a LAN, but only 3 devices can be detected via VXI-11.
For the SPD1168X I have to enter IP address manually. Is there any way to find SPD online?
