Increase RF-output to +/- 5V

Hello, I have the following question.

Is it possible to increase the output voltage of the RF outputs of the STEMlab board (e.g. STEMlab 125-14) from +/-1V (2V peak-to-peak) to +/-5V (10V peak-to-peak) by software ?
If not, would there be a circuitry measure that could be connected directly to the output to achieve this goal, e.g. a suitable amplifier add-on board that also has RF inputs and outputs with suitable SMA sockets ?

I need a symmetrical output voltage of +/-5V (full AC no DC) to supply an amplifier output stage, which amplifies the low-frequency measurement signal to the actual level of +/-40V.

Friendly greetings.

Hi ThirdClassToaster

Go to Minicircuits.com, you will find affordable and high quality amplifiers. They also have 50ohm transformers if you are using 10/12/14 version of RP.
