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:


SDG6052X_5Vpp_T2ns

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.

Attached is an example for the SDG6052X after a power loss.

It was set to a 100 Hz, 1 Vpp sine wave.
Utility – System – PowerOn was set to “Last”.
Utility – Output Setup – Power On State was set to “On”
Utility – Output Setup – Amplitude was set to 20.000 Vpp, i.e. no limit set.

That’s how a well behaved AWG handles mains power outage and -return.

What I ask myself all the time is whether the "gap" between SDG2000 and SDG6000 will ever be filled....

Was this measured with peak-detect enabled? At 4Ms/s it is easy to lose a spike.

There is no spike. Simple as that.

The scope screenshot doesn't show that information so if you have no useful information to add, it is better to wait for Tautech to acknowledge he enabled peak-detect in order to do this kind of measurement correctly or to redo the measurement with peak-detect enabled and show a new screenshot.

You just have to be condescending aren't you?

I MEASURED. There is no spike. With Peak detect, without, with different scopes.
I have that AWG for 3+ years...
I would not post that if I didn't have veritable information and was sure...
Haven't you learn that by now?

It's a trivial case that every dealer can show. But the fact that it is able to keep the zero offset does not prove that it is also able to preserve a user-defined DC offset (i.e. the logic levels). While the latter is obviously of more importance

Not my screenshot above.

However I might have done it a little different using a Normal Trigger waiting for the signal to return after power ON.
But not today, too much to arrange for EMEX the week after next.....

Well, you should have written that to make your point clear to everyone. That is useful information.
