Siglent SDG6000X series 200-500 MHz AWG's

[JanL]

Hello there, I stumbled across the SDG6022X as an signal generator for a reasonable price. Looking at the data sheet I am missing information about rise/fall times for different output voltages. Does anybody know what times to expect for 5, 10, 20V outputs?
Thanks, Jan

I only have SDG6052X here, but this shouldn’t make any difference:

Firstly, I won’t be able to show you the rise time at 20 Vpp, because this instrument, like any other AWG in this class, can only output 10 Vpp into a 50 ohm load. There’s certainly no way to get a fast pulse with single digit nanosecond risetime into a high-Z input without significant degradation. So we have to stick to 50 ohms.

The fastest specified rise-time of the SDG6000X is 2 ns. At least my specimen is a little faster and manages to stay below 1.7 ns at 5 Vpp:

For 10 Vpp it was a bit of a hassle already, because that level is too high for a 50 ohm DSO input. I had to fit a 6 dB inline attenuator and consequently you’ll still see only a 5 Vpp pulse in the screenshot. But it is 10 Vpp originally – you can also see that the rise time got quite a bit slower now (~2.3 ns).

Thank you very much. It helps a lot with my decision.
