Hi Siglent support,

Thank you very much, that worked perfectly. 

I was using the latest version on your SDS 1000CNL page :
http://www.siglent.com/en/product/detail.aspx?id=100000004399111&nodecode=119008001
You might like to update the version on this page and all other product specific pages.

You might also like to contact Sameer Dhiman so that he can update his installation notes here :
http://siglent.freeforums.org/make-easyscopex-work-and-recognize-usbtmc-dso-t85.html
I am sure the new software will mean that Sameer's installation procedure is so much easier.

Best regards,
John

I've had a bit of a nightmare with installing USB drivers to use with the likes of Hantek/Siglent. This is on Windows 7.

The problem is Windows will automatically go and find drivers based on VID:PID over the internet, and decide that whatever it finds is a "newer" driver than the manufacturers actual latest supplied driver. I believe there must be many China manufacturers using the same VID:PID as each other for similar drivers.

The way around it is to delete (and permanently remove) all drivers associated with your instrument from the control panel/system. Then make sure you disconnect from the internet and install the manufacturer provided drivers. The ridiculous Windows automatic driver search will hence fail and you get the proper driver installed.

Also, make sure you set your device up with USB-TMC rather than USB-RAW if you intend to use NI-VISA stuff.

ETA: I have had to go so far as to use REGEDIT and search for VID/PIDs and delete the bastards left behind even after removing the device from control panel! 

Next time you run into USB problems give USBDeview a go , it saves having to hack through the registry .

Hi Siglent Support,

I have an SDS 2074 and installed the latest firmware.  I have a question regarding roll mode.  Will zoom function be enabled in future firmware releases?   Today it pops up a message "Function isn't useable"

I thought it was possible to adjust the scale and effectively zoom in this way, but the waveform is not zoomed in on the center of the screen.  So if you have an event you want to zoom in on, you can move horizontal position to find it.  But once you adjust the scale, the event disappears and you are effectively zooming in on a different area. So this is not an effective equivalent of zoom function.

On a side note, I believe others in the forum were interested in knowing if peak detect in roll mode was supported, and it appears to be supported in latest firmware (FYI to forum members).

Thanks,
Don

Hi Don
Latest I am aware of is 1.1.1.35.1
My 2304 will zoom from a 50/S div timebase.

Press Default to clear all previous settings.

[don]

Hi,

I have the same firmware.  Here is the sequence from default state:

Press Default button
Press Horizontal button
Select Roll mode from menu button
Press stop button
Press zoom button "Function isn't useable" is displayed.

Does this work on your scope?

Also I noticed zoom does not work when decode is enabled.

Thanks,
Don

Hi,

For SDS2074 -- I noticed that I2C decode only works properly when memory is 1.4Mpt or less per channel.  You can select 7M or 14M, but if you do, the decode does not work.  You can see it's trying to decode but messages are not showing correctly.  This does not seem dependent on the sample rate or time base.  System also locked up a couple times but hitting default restored.  By lock up, I saw behavior such as not being able to use Single acquisition if decode was selected. 

As mentioned in previous post, zoom does not work in decode. However, you can adjust the scale after capture and that does work as expected unlike in Roll mode.

Thanks,
Don

I get the same result.
I have not used Roll mode, but will experiment with it and forward any problems to Siglent
For Decode, I Run/Stop and then use timebase and H Position to see areas of interest as you have mentioned.
Interesting comments re Decode and Mem depth. Worthy of more research.

Consider moving this discussion to the SDS2000 thread

[don]

Also, looks like I spoke to soon on being able to change the timebase / H position with decoding.  The decoded messages get out of sync with signaling when you change the timebase.  So you can't really scroll to see signaling and messages over one another.  There are combinations of memory and time base where you can, but it's hard to figure out how it works.  It think zoom is the ticket since it does not change the sample rate.    Hopefully zoom gets enabled for roll mode and decode because it defeats the purpose of large memory if you are confined to screen view.

Some member asked if you can scroll through list view, select a message and have it take  you to the waveform.  From my testing this does not seem possible in current firmware.

[tautech]

Use a slow TB setting, then Run/Stop, then adjust TB and H Pos to see long Decodes.
Close examination of 1/2 second Decodes quite possible this way.

[don]

For example, I'm at 1.4Mpts and 20MSa/s (5ms/div).  It decodes data fine and I see 12 messages but too small to read.  As soon as I change the time base to zoom in, the decoded messages go off screen but the signaling of all 12 packets stays on screen.  Further scrolling of horizontal or changing time base does not help bring back decoded messages.  Unless I change timebase back to 20MSa/s.  It's very odd.

When I have some time I will investigate more.
What Protocol are you decoding?

Thank you! Just installed it now and will no doubt be forced to make use of it soon!

It is nice to see your guys giving back
Great job!

I have an SDG1025 and like to use a high accuracy external clock with it.  Setting the CLK Source to external works fine until you power off the unit.  When you power it back on the CLK Source will still say "external" but in fact it will be using the internal source until you toggle it to internal then back to external.  This is very disturbing.

In addition the frequency counter function seems to always use the internal clock regardless of the CLK source setting.  I see no reason for this limitation.

Firmware version is: 1.01.01.31R1, Harware: 02-00-00-22-26

Are there any plans to fix these issues in the next firmware release?

Thanks,
Katie

[nctnico]

I think there are similar issues with other settings.

Dear Katie,
the first problem about CLK setting, I think this is because the default setup does not include the CLK source setting. I will let the R&D department know that.
the second issue about the counter CLK, this is not a problem, cause the counter always use the inner CLK to count, not every user have a external CLK. Do you want us to add this option to SDG1000 series?

This is less of an issue to me personally than having the CLK source setting remembered.  However, I think it would make the counter more useful, to have the option of using an accurate clock. So yes, I think you should add that option -- or simply use the same CLK source setting that the generator does.

[Siglent]

the new firmware of SDG1000 series will be released soon which solved the first problem. we will upload it to our new website at that time.
the second problem is that while you set the CLK source to external , the frequency counter will choose external too. so we will not correct it.

Any comments will be highly appreciated.

    I want to ask you something about the Siglent windows drivers... I have a Siglent SDG1020 AWG and a Siglent SDS1072CML oscilloscope, both with the same problem... The driver on the CD has a different hardware ID than the actual hardware ID of the equipment... And of course, because of this, Windows won't install those drivers... And even if I change the hardare IDs in the .inf file, the software won't see the equipment...

    The scope and AWG works fine with the NI VISA drivers... but still the same problem... The Siglent software doesn't see anything connected on the USB...

The operating system of your computer is win7 64bit?
You may need install the version  5.1.2 of NIVISA.
It's the link: http://joule.ni.com/nidu/cds/view/p/id/2914/lang/en

It's good to see that SIGLENT is supplying both the 32bit and 64bit drivers.
Thanks SIGLENT

Hi,

I was getting ready to buy a Siglent SDG1025 but after doing a little bit of research I got the impression that as long as the equipment works fine you are good but if it ever fails it will be a nightmare to get guaranty support.

Is this true? Anybody has any experience getting guaranty support from Siglent?

Sorry, I know is a stupid question but at $350, I would really like to have the peace of mind that if something happened to the equipment it can be repaired with minimum hassle.

Thanks.

[nctnico]

What are the waranty regulations in your country? If you are concerned with waranty I suggest to buy from a local dealer.

[Rene]

I suggest to buy from a local dealer.

The problem is that I have no idea who the authorized distributors are. Their website (http://www.siglent.com/ENs/) has zero info regarding where to buy (unless I totally missed something).

But even if I buy from a local dealer, once the local dealer warranty expires (most likely 30 days) I am on my own and I would have to contact Siglent directly and that is were it starts to get scary from what I can see.

[Siglent America]

Before this past summer we did not have an office in North America so any warranty repairs here had to be sent back to the factory. That is no longer the case since we do have a North American headquarters in Cleveland, Ohio and we can handle any warranty repairs here in this office.

We are currently working on a North American website that will list all of our distributors and local reps here. If you are in the USA or Mexico you might try any one of our distributors:

Saelig
TEquipment
Electronix Express
Emtesco
Circuit Specialists

In Canada:
RCC Electronics
dipmicro
