can you share? we didnt pursue as its not critical, i only use sine and sweep so far. it works well so far as ataradov said. but capable to upload our own arbitrary data will be bonus...

Below are temporary screenshots in Chinese. This is just a draft
Update: English screenshots attached

0. Disconnect the device from PC

1. Run the black Uni-T device manager

2. Plug the device to PC USB 2.0 port.
Wait for the device to show up under the USB folder.

3. Right click on the device string UTG900 (0x0834:0x6656:129)

4. Choose the top option from the dropdown menu
 - "RUN Virtual Control Panel"

5. The SG Virtual Control Panel is running now.

6. Right mouse click on the virtual device screen. Choose the second option from the dropdown menu.
 - "Send ARB file"


7. You'll get the mini-window popped over the virtual unit mockup. Press the [...] button and choose the file you prepared and saved previously from an arbitrary wave editor. That was "waveform3.bsv" in my case.

Push the bottom right "Load" button and voilà!

Try to avoid USB 3.0 ports until you get everything up and running on USB 2.0. I'm not sure yet regaring this requirement.
Update: USB 3.0 was a possible culprit for some of the problems arisen during this misadventures.
Two of my eldery notebook ports are provided by separate chip from Renesas Electronics and it seems the connection to the Uni-T was quite unstable on these ports. That could be just UniT-Renesas compatibility (or drivers) issues only and not USB 3.0 in general. The system is Windows 7 Professional.

Another surprise, the data uploaded is not persistent. No waveforms survives over power off.
There were something resembling a possible solution in Waveform editor "Down file" top menu, but that's just failed to work with this generator.

Also I can't figure out how to load wave file in any slot but the first.

at least it can output user data for a while during turned on life. maybe you can ask them again on how to save in user ROM so it can survive power off. thanks for your tips. :-+

Yes I'll try to contact them tomorrow. It's too late there in China right now.

I'd prefer to write some of my custom waveforms to internal slots in place of their wave samples.
I hope someone to hack the firmware or internal storage one day.

It was not so smart idea to equip this device with 4k points storage for 14 bit dac. 214 = 16384 hence 16k points is a bare minimum for a "square pixels". To be honest it appears to be a marketing decision with no technical reason behind it. Just to avoid cannibalization of next level generators segment.

Next day update: I got an answer from them in Chinese that storing user-defined waveform in non-volatile memory is not possible.
And it looks like the engineer from whom the messages are forwarded is a UniT store tech guy, not a device developer. I am not sure though. It might be a good idea to get in touch with factory engineers, if possible at all.

I've the same Windows version with all available updates installed till the end of Win7 support.
https://www.uni-trend.com/uploadfile/cloud/Software/Instrument-software/UTG900E%20software.rar
https://mega.nz/file/lnxyhSoS#iiYQhTb1ZJCcMvZ7f9O0h2l3KMa1LJCeYTKS8bri3VY all components extracted from installer package.
I do not see any problems with running the DPInst64.exe file separately from the package. Fresh screenshot in attachment.

You may also try to use LibUSB from original source https://sourceforge.net/projects/libusb-win32/files/libusb-win32-releases/
The library version in the Uni-T package is 1.2.4.0
Hardware id is VID_6656&PID_0834 if required.

Hi all
Does any one know if there is a calibration mode (hidden menu ) on the UTG962?

 the only bad thing I have found with the UTG962 is the rise time is limited to 15ns
 so even though they say it has a square wave up to 20Mhz it starts showing a trapezium
 over about 3Mhz and the display on the UTG shows the same angling of the sides . /`\

 Other than this it has some really nice features and clean wave forms .
But I some how would like to know if it has a hidden menu that allows to adjust the frequency error.

i doubt there is hidden menu, esp to calibrate square wave (rise time) the menu system is very simple, not much extra options. you may compare your square wave with what is posted at reply 14 and 15... https://www.eevblog.com/forum/testgear/uni-t-utg932utg962-200msas-function-arbitrary-waveform-generator-220394/msg2845722/#msg2845722 if you really need fast rise time, you may want to enable synch output and play with signal frequency to get fast rise time square wave, or build yourself a fast risetime edge circuit using fast comparator or logic IC feed from the AWG, ymmv.

Thanks .
My square waves are the same . There is a update function . It was only that most have a way to calibrate the frequency
@ 10Mhz or another mid point .
 But other than that as you said the menu's are very easy to navigate . It works out the Box and has some very nice features.

All the best

I grabbed the UTG962 today as well. Came out to 145USD after tax and with a $4 coupon. I'm excited to get my hands on it, as it seems a pretty big step above the Feeltech units I was originally considering. I've already got an RF signal generator, but I wanted an inexpensive function gen for arb waveforms to complement that for lower-frequency work. Hopefully this fits the bill well. Plus, it's small, and with limited bench space that's important.

Looks like it'll be a month or so for it to get here from China.

Hi everyone,

Some Aliexpress listings are selling a "UTG962E"  vs "UTG962". Is there any difference?

The actual unit I have does not have "E" on the label. But if you look at the Uni-T site, the only model they list is the "E" one.

I see no specs difference.

So I guess "E" is basically the version they decided to release for wide markets. It is possible that they have more global certifications. The original version was China-only with no documentation in English. And it was not even listed on the English version of the site.

I don't think there is any functional difference.

I guess it's all the same.

axel
The shop I bought my gen from for $105.8 now set the price point around $165
In the same time there are some other shops on Ali that didn't push the prices yet
$112.99 for UTG932 plus two coupons (US $6.00 off per US $65.00) (US $4.00 off on US $50.00)

No , Differance   . The E as far as I know was published last December but there does not seem to be
 any listing on the official UNI-T site . Just use the official Factory site of uni-t on ali .
  Correction .. Sorry There was something in one of the manuals and it put an E after the number . But Not on the the unit itself maybe
 a translation thing ..  Maybe some one will shoot me down on this . I also saw it . and just stayed with the official site.

 I put the Ali link few blogs up .

  @ axel.
  I think you will be very happy with it . I just love my one . there is a slight learning curve . as it has many cool features .
  I would download the manual from uni-trend.com   ..It's about 30 or so pages .  help pass the time  :-+ .
  So you can dive straight in and enjoy it when it arrives . :popcorn:

i cant remember who told me whether a member here (earlier post?) or a message from seller/uni-t that the fact is "E" model is exactly same as non "E" model, except "E" model is for international (non-chinese) market. i still dont know whats the logic but i remember thats the fact. you can google in their website the non "E" but its all chinese letters.

but I wanted an inexpensive function gen for arb waveforms to complement that for lower-frequency work.
i hope you will not get dissapointed with your buy if you are thinking high about "arb" feature. it has typical built-in arb function but if you want to make your own, there's a little bit of works to do (read earlier posts) and cant be saved when the device is turned off. we dont have issue as we dont really need very specific arb function, i guess the typical built-in like pulse will be enough one day ymmv.

I also ordered Analog Discovery 2 osc/arb gen. "Two-channel arbitrary waveform generator (±5V, 14-bit, 100MS/s, 12MHz+ bandwidth)". It's a PC-only device, no standalone mode.
https://store.digilentinc.com/waveforms-download-only/ free software download with device emulator.
And the app is a way better than any other software I am aware of, including Rigol, Unit, Agilent etc.
