Siglent SDG6000X series 200-500 MHz AWG's

<< < (79/104) > >>

berke:
I ran into some other annoyances, apologies if they have been already mentioned.

1. While generating a square or pulse signal, if you change the duty cycle, the signal goes through zero for a few ms.

I then tried to modulate the PWM on CH1 from CH2.  Modulating with a sine wave gives a smoothly varying input, so that's good, but I wanted to switch between two levels manually, which brings to the next point.

2. You can't modulate using the "constant DC" output.  (In the end I used a pulse waveform on CH2 using burst mode, manually triggered.)

3. Another thing that is really annoying is that you can't set the duty cycle to 0 or 100% in square or pulse modes, you get an annoying beep.

4. Unless you turn it very slowly, the rotary encoder misses pulses.  How hard is it to count pulses ?

5. Not a big deal, but it would be nice if you could set Vlo > Vhi for "inverted polarity" PWM generation.

6. Also, is this thing supposed to remember its settings across power cycles ?  Every time I power it up, I have to set the voltage range to 0-3.3 V from -2 to +2 V.  Thankfully I haven't fried anything yet but it may happen one day.

I did some measurements on the AWG today. It's a SDG6022X with no improvements :)
The level was always -10dBm and the reference clock came from the internal oscillator. I adjusted this two weeks ago and today I had a deviation of 40ppb compared to my Leo GPSDO.

I'll let the measurements speak for themselves, the parameters can be seen on the screenshots. I hope it is of interest to you.

I just saw that the phase noise markers are a bit shifted, sorry for that

mawyatt:
Close enough :-+

Impressive AWG performance!!

If you have access to the little brother SDG2000X, might be interesting in how well it behaves ::)

Best,

Unfortunately, I don't have access to the SDG2000X, so I can't make any comparisons here
