How can I get the Peak Hold value of a single measurement?

Question

How can I get the Peak Hold value of a single measurement in Receiver mode? Is there a remote control Sequence for this?

Answer

Below you will find a command sequence as an example. As you can see I configure bargraph in Receiver Mode for 500 MHz with detector Quasipeak and I do 4 measurements.

After this I do a query on the last single measurement result and on the Bargraph MaxHold result.

TRACE? PHOLD

As you can see, with INIT:CONT OFF you change to the single measurement and with DISP:BARG:PHOL ON the bargraph display is activated..Each INIT starts a single measurement. In my case 4 single measurements are done. TRACE? SING reads out the last (current) single measurement result, the command TRACE? PHOLD reads the bargraph MaxHold value of all four measurements.. Each PHOLD result is made up out of two values, absolute level and frequency.
