HOW TO CALIBRATE SIGLENT SDG1032X
« on: October 14, 2023, 05:57:53 pm »
Hello, I bought a Siglent SDG1032X signal generator and a Siglent SDS1104X-E oscilloscope in 2019, but playing with telnet I deleted the calibration file and the serial number of the SDG1032X, now that I have just bought a Siglent SDM3055 5-digit bench multimeter and a half this week, I want to take the opportunity to calibrate the SDG1032X.
I have written an email to Batronix where I bought it to explain how to calibrate it and/or to provide me with the calibration scripts. They replied that I should consult Siglent directly. I consulted Siglent a week ago and they have not responded.

Can someone here explain to me how to calibrate the SDG1032X and give me the calibration scripts, thanks in advance.

And by the way, you know how to calibrate the SDS1104X-E and if you explain it to me, it would be perfect.

Maybe our recovery packages can help.

Update to latest FW and OS then run Self Cal after prescribed warm up period.

Hello Tautech, thank you very much for the recovery kit, I put it on a USB and it ran, it seemed to work, but it stayed the same since it already worked and I already had the latest version of the software.
That is to say, it stayed the same as it was. :(
Recovering the old telnet thread on the SDG1032X, I was able to manually modify the file by Telnet and put my real serial number back into it.
But calibrate it I still don't know how to calibrate it...
My reference is the SDM3055 that I bought a week ago and it comes calibrated.
Well, putting the SDG1032X in:
C1: DC 1mV the SDM3055 measures 2.762mV and the UT-71E measures 2.7mV
C2: DC 1mV the SDM3055 measures 2.834mV and the UT-71E measures 2.8mV

If anyone knows how to calibrate it and explains it to me, I would appreciate it.

In the old service manual it refers to a calibration script and gives a link that no longer exists. I think years ago this calibration script was available, today there is no trace of it, and I don't know if the current firmware allows it...

How are you outputting 1mVDC from your AWG? The signals are generally AC, with the option for a DC offset.

Thanks,
Josh

Being on channel 1 (for example), press the "waveform" key then go to page 2, click on "DC", and with "DC Offset" you choose the voltage.
It leaves you from -10vdc to 10vdc

As advised, return to Siglent in Germany for recalibration.

Try testing the ACVrms and see if that comes back accurately.

SDG1032X - Sine wave 1KHz 1mVrms
SDM3055 = 0.991 mVrms

SDG1032X - Sine wave 1KHz 1Vrms
SDM3055 = 1.00850 Vrms

That's pretty good. Now, try again, and view the DC voltage BEFORE applying any DC Offset.

When I talk about DC it is a pure DC, without AC of any kind.

Thinking same.
When compared to Output Characteristics from the datasheet (P8) it seems within spec.

That's standard and documented in manuals for at least HP/Agilent/Keysight arbitrary waveform generators. Dave even made a video about it.

Yes, Cal scripts are now confidential.

I'm hoping Siglent know the difference between calibration and adjustment...

Why would they make adjustment scripts confidential? It's not like something like an AWG or power supply needs extremely expensive, rare equipment to adjust. For this adjustment a good DMM would probably all that's necessary.

That's true, looking at the initial measurements they seem to be within the 1% + 3 mV uncertainty as specified in the manual. So I wouldn't count on sending it for adjustment changing anything.

An AWG is not a DC voltage reference.

For better reference, here's my SDM3055 and SDG2122X:

AWG: 1VACrms
DMM: 0.99997Vac
DMM: -2.748mVdc

AWG: 1Vdc Offset
DMM: 0.99922Vdc

AWG: 1mVdc Offset
DMM: -1.788mVdc

Here we can see that (ignoring likely minor voltage loss over the cables) that the DC offset is only an offset, and not an accurate voltage source without knowing what voltage you're actually offsetting.

Test DC before and after applying offset and you can see how accurate the offset is.

I already imagined it, but the calibration plus the round-trip shipping is respectable money.
What I don't understand is that Siglent itself has released a menu to calibrate them in the latest firmware of its multimeters, and in the SDG1032X it cannot be done.

Checking if specs are met is outlined in the SM under Performance verification which anyone can do with the prescribed equipment.
Adjustment is a SW process and I know US branch has a Fluke 5200 for such needs. Not sure about EU.

Why would they need a seventies-era AC voltage source to adjust an arbitrary function generator? DMM, scope, maybe power meter and spectrum analyzer for flatness and harmonics, but why a voltage source?

You haven't demonstrated a lack of precision yet.

Measure your DC voltage WITHOUT offset applied.
Measure your DC voltage again WITH offset applied.
See if the difference in DC voltage is equal to what you set as the offset.

I'm using the SDG1032X as a precision  DC voltage source to test a 16-bit ADC to see how accurate and stable my design is, noise levels etc.

As I said earlier, an AWG (in this case the SDG1032X) is NOT a precision DC voltage source. DC Offset is COMPENSATION only. The lower your voltage is, the less accurate it will be especially when you factor in voltage loss over cables. From what you posted, your AWG appears to be functioning as expected.

If you need a DC voltage source with that much accuracy, you need to buy or build an actual voltage source. This thread has a (not cheap) DIY DC voltage source: https://www.eevblog.com/forum/testgear/elektor-voltage-current-calibrator-project/new/#new

There are some great inexpensive DC voltage sources out there, but not with super high accuracy or adjustable voltages. If you're on a budget, you'd probably be better off getting a calibrated DC Bench PSU with good adjustment ability.
