AWG Amplifiers

[bartdinger]

Does anybody have any recommendations for a waveform generator amplifier? Most AWGs (built into oscilloscopes at least) seem to only have fairly low signal level outputs, but I have on occasion needed to be able to replay a stored signal at the original signal levels with either decent current drive or higher voltages. About the only reasonably priced thing I've found is a Rigol PA1011, most other solutions seem to cost a fortune, or should I say more than I would be prepared to spend on a piece of gear I wouldn't use often. I don't own I rogol scope, but it looks like this amp can be setup via usb and used with anything. Anybody have an experience with this or other amplifiers?

What peak-peak voltage levels are you looking for?

15V p-p would be perfect.
That Siglent thing looks like it would suit my needs perfectly. Thanks

I have a couple of questions.

#1. It has an input impedance of 15kohms. That means you might need to use a 50ohm pass through terminator if you want waveform fidelity when coming from the waveform generator. Why would they not include this simple thing as a selectable input impedance?

#2. It also has a very low output impedance, again no 50ohm selectable.

The output impedance of the instrument Zo is less than 2?,
and the range of output voltage is -13V ~ +13V(RL=1K?).

What are the implications for using this where a 50ohm source is preferred?

And one point to consider; its bandwidth is only 1MHz.
