UNI-T UTG932/UTG962 200MSa/s Function Arbitrary Waveform Generator

[valcher]

I would like to clarify what the FPGA firmware is responsible for, the control interface?

Синтезатор (synthesizer)

This firmware UTG900E.bin doesn't have SRC check
We can change FW version to any we want.
Now my 3.06 changed to 1.09

[Aldo22]

normal or not ?? Is my copy bad?

I don't know enough about it and I don't have such a device, but why don't you compare the information in the data sheet with your measurements?
Like "phase noise" and "shake": https://www.batronix.com/files/Uni-Trend/UTG900E/UTG900Edatasheet.pdf

[Aldo22]

Hi,

because there is no value for shake at sine waves. And because I don't understand what a value of -125dBc/Hz means at phase noise.

I understand that you would prefer it if someone with an UTG932 could confirm your measurements.
I can't, but I think that some jitter is normal. It's still a cheap FG.

If you want to know more about it theoretically:
German: https://de.wikipedia.org/wiki/Phasenrauschen#Messung

Lots of background (English)

Maybe you could ask the question more generally in another subforum. Maybe "Metrology" or "Beginners", I don't know.
There are already such topics: https://www.eevblog.com/forum/metrology/phase-noise-measurement/msg3337416/#msg3337416

I seem to have found what the write error problem is, the new UTG900 has w25q64 memory, and the old w25q80 memory. And also, there is a slight difference - see the photo.
Now I can't confirm my guess yet, because there is no such memory, but I ordered it and am waiting for it.

And also, there is a slight difference - see the photo.

Are the FPGA chips used in them completely identical?

[valcher]

All chips are identical, only the FPGA itself is from different manufacturers.
My guess was not crowned with success, I tried to flash a new flash with a programmer, but it did not bring any effect. Moreover, I accidentally rewrote the native flash image and now I can’t revive the generator. If anyone can share the image.

[valcher]

I found the original firmware and restored everything.

Version?

[valcher]

Version?

FPGA - 1.07

[Yuriy V.]

Anybody has Software (firmware) version 1.09 BIN file?

[Evgeni62]

Does anyone have firmware with Russian language?

[valcher]

@Evgeni62
It seems like this never happened.
@Yuriy V.
What is the difference between 1.09 and 1.07?

[Yuriy V.]

What is the difference between 1.09 and 1.07?

Scroll above, I posted a screenshot - and you will understand what I’m talking about.

Inrush Current when power switch moves to ON.
