Example:
CALC:MARK:FUNC:MDEP:SEAR ONCE
Executes the search of an AM modulated signal at the currently
available trace.
Manual operation: See " Search Signals " on page 303
CALCulate<n>:MARKer<m>:FUNCtion:MDEPth:RESult<t>?
This command queries the results of the AM modulation depth measurement..
To get a valid result, you have to perform a complete measurement with synchroniza-
tion to the end of the measurement before reading out the result. This is only possible
for single sweep mode.

14.5.12.2 Example: Measuring the AM Modulation Depth
This example demonstrates how to determine the AM modulation depth in a remote
environment. Note that without a real input signal this measurement will not return use-
ful results.
//-----------Configuring the measurement ------------
*RST
//Reset the instrument
FREQ:CENT 100MHz
//Set center frequency
FREQ:SPAN 10KHz
// Set span
CALC:MARK:FUNC:MDEP ON
//Activate AM modulation depth measurement.
//--------------Performing the Measurement-----
INIT:CONT OFF
//Selects single sweep mode.
INIT:IMM
// Perform a single measurement
CALC:MARK:FUNC:MDEP:SEAR ONCE
//Initiates a search for signals in the current trace.
//---------------Retrieving Results-------------
CALC:MARK:FUNC:MDEP:RES?
