Reading out Auto Peak Trace Data

Question

I have made a measurement with the Auto Peak detector.

When I read the trace data with:

TRAC? TRACE1

I only receive the Max Peak values and not the Min Peak values.

How can I also receive the Min Peak values without having to perform a new measurement?

Answer

After you get the Max Peak values with

TRAC? TRACE1

send the command

DET NEG

then read the trace again with

TRAC? TRACE1

You will now get the Min Peak values.
