I have done the work and now my Siglent became SDG2122X.
But I can not install the USB drivers for EasyWave.
Can someone help me?
Thanks

Updating


I've install the driver usb but EasyWave don't see the SDG2122X
Which drivers did you install?
What OS are you using?

They are contained within the NI VISA package, IIRC it's ~550 Mb but the divers themselves are only a few Kb.

Thanks Tautech.
I'm installing from cd (drivers for SDG 2000x series), in Siglent's site the drivers pages does't work
I use Windows 10.
Before changing the unit everything worked, now he tells me that I have to connect the instrument.
Thanks

Updating  |O

I understand, I install the device drivers and I had to install the driver NIVISA.
Now it works perfectly ..... thanks Tautech

If you mean these drivers, then no they aren't for general instrument to PC communications, they're Labview drivers.

Just a quick question: basically the hack is working until P21R2 from one week ago?

I think that most others mileage may vary, but I cannot telnet thru PuTTY or Linux after upgrading to P17R5 months ago.  I have a username/password at the PuTTY telnet login.  Or no viable connection in Linux.  Good luck!

If You dont mind taking the generator apart, the upgrade is still possible using the serial port header on the processor board.

Hello,


Look in the other thread mentioned above, I have posted the pinout there.

br,
mike


It seems to be a 3.3v levels serial, can I use a serial to USB adapter to connect with it  ?
Thanks

There seems to be a new firmware P22R5 just made available
http://www.siglent.com/ENs/prodcut-gjjrj.aspx?id=1134&tid=16&T=2
installed it and at least it installs and boots, and 120MHz output still works ;)

However in the IP-settings I thought I will almost going to have a bit of a bad day  |O
What's up with not being able to set the IP _with_the_wheel_ to something like 192.168.x.y?? When rolling the wheel the max of the first number is 99?? Using the keypad it works WTF..

otherwise seems like a nice cheap little siggen. I'll test phase-noise at work at some point..

New FW for the SDG2000X series:
http://www.siglentamerica.com/gjjrj-xq.aspx?id=4960&tid=15

12.9 Mb

From the email I was sent informing me:
Fixes:

1. Permit setting the frequency to 0. 0 Hz would mean that the DDS accumulated phase word would be held/not change with time.
2. Fixed some bugs
a) Single Channel AM Modulation Output Amplitude Is 9.3% Low
b) Manual trigger can not trigger both channels at the same time
c) SW bug regarding the modulation with noise
d) Display graphic error for displayed wave shape
a) Can not save the last state after the update

Can others elaborate on this ^^^ so it can be reported to the factory.

It's never going to lose frequency lock, so half the noise is amplitude and half phase.  Basically just measure the noise floor using a high Q filter and subtract 3dB.

If your USB adapter uses 3.3V level signals you can safely use it. Altough I would measure it first  :)

Hi,

I just got my SDG2042X. Updated to latest firmware and seems to work just fine.

When reading the remote command manual I didn't notice any way to upload ARB data via the SCPI commands. Not a nice surprise. Am I missing something?

Is there a workaround?

/K

Kazam,
Please contact us at
info@siglent.com
and we will see if we can help you.

I sent an email. I can't get this to work and I need it to work.

/K

FYI
In an email conversation I had today with an 2042X owner that works associated with a local Cal lab....when he got his he sent it to the lab for some checks to satisfy his curiosity:

I took the 2042x up there & asked them to check it. They checked it at 1Hz which is a more stringent test than 40Mhz . It was out by 35nHz (nano hertz) the counter was plugged into their atomic clock standard as a reference. Apparently this is as good as the Agilent equivalent instrument which they have. Only the rise time is slightly better on the Agilent.

There is little use quoting these kind of anecdotes because they give a false impression of the capabilities of a type of instrument. The only thing what you can rely on is the specification when it comes to accuracy (especially over a temperature range!).
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

So you don't think that it's interesting info ?  :-//
What capabilities are you referring too, the lab was checking the instrument over for one of the company staff, that's all.
And it was done in one of NZ's top Cal labs.....most probably under controlled temp conditions too.  :P
Furthermore it wasn't even a unit that I'd supplied.  :(

No because you cannot rely on it. It is like measuring one resistor (say A) from a box with 1% resistors and if resistor A is within 0.01% stating the entire box must be at least 0.01% precise. And then there are temperature variations, aging effects, etc,etc. People have Cesium and GPSDO reference clocks for a reason when it comes to accurate time related measurements.

Newest member of the Silent SDG2042x gang.  Really liking the unit.  I bought it because of the performance and features.  Plus the firmware updates that keep coming.

Siglent nice job with this one.

My two cents on the accuracy/stability of the reference in the 2042X. A few months ago, I checked my unit against my HP GPSDO. I checked the frequency error at quite a few points from the audio range, up to 120 MHz. I don't remember the exact numbers, but the error was a linear percentage of frequency across the entire range (which is what you would expect, if things were designed/working correctly). I do remember that at 120 MHz, the error was only a few Hz. After initial warmup, the FG output was very stable.

Yes, this is only a sample of one. However, it does give me confidence that the internal reference in my unit is a very good one, for a piece of mid-range equipment. With this level of accuracy and stablity, I don't see myself hardly ever needing to use an external reference.

Did recently purchase SDG2042X. Find it rather excellent:
- built like a tank, has very solid feel to it
- all is working according to specs
- no signs of rust  :-+
Go Siglent!  :clap:
And since more is merrier...
Did read  the app note about phase locking multiple units:
http://www.siglent.com/ENs/qyxwxx.aspx?id=1364&sid=208
Example is done at 60Hz, rather easy case.
Can I expect phase locking to be effective in all operation
modes (DDS, Arb) up to max frequency?
What is expected jitter (ns)?

I was wondering if we could put a request in to have the frequency counter feature display graphs?  At the moment, it displays just the stats.    :-+

So are you suggesting that this is jitter number also
between two synced units  or even
phase locked channels on same units ::)?
And also same when units are synced via:
a) ext ref to both units
b) unit 1 ref out - unit 2 ref in

There is not at all this kind of specifications.
This specification about 150ps is inside 1 channel signal cycle to cycle jitter and it is not even Max. It is Max RMS jitter! Real max jitter is peak to peak (with this we need live in real life) and this is not specified.

There is also not specified time jitter between external Ref In signal and output signal (but if specify it, then need also specify RefIn signal ... and so on.  Also I can not see channel to channel jitter.

If practice and theory is not equal it tells that used application of theory  is wrong or the theory itself is wrong.
It is much easier to think an apple fall to the ground than to think that the earth and the apple will begin to move toward each other and collide.

Maybe someone has 2 units and can test (40MHz+)?
Or what RF pros think? I think that probably it will
be ok with ext ref, not so sure about in-out scheme...

You need to downgrade to P17R5, and after mod you can upgrade to P22R5.

It' a great generator, I'm able to test numerical receivers, one channel loaded with an arbitrary waveform (acquired with a scope) and the other generating the carrier, modulated (FM) using a bnc cable connecting the arbitrary output to the external input.

For those of you who have a SDG2000X (or any Siglent SDG) generator, we thought you might be interested in this new application note we just posted to www.SiglentAmerica.com.

"Custom Waveforms using EasyWave and CSV Templates"
The zipped download also includes some example files.

http://www.siglentamerica.com/USA_website_2014/FAQ/SDG/EasyWaveCSV.zip

We are trying to post more and more helpful application notes and FAQs to our website.
We hope that you find these useful.
