ZNB: Power off at sweep end possible?

Question

I use the ZNB to measure S21 of amplifiers. But these amplifiers are designed for pulsed operation only. They become damaged if they are driven with a CW signal.

For the measurement I use the single sweep mode, but after end of the sweep the ZNB still applies a CW signal.

It is necessary that the output of the ZNB goes off after sweep end. How can this be archieved?

Answer

Unfortunately the setting for that is quite hidden in the ZNB menue:

At the bottom of the display select "System"

Select "System Config"

Open the folder "Power"

At "Power Mode at Sweep End" choose "Reduce"

Now the output of the ZNB is off at sweep end.
