//Returns the frequencies of the temporary markers at the power offsets
CALC:MARK:FUNC:NDBD:QFAC?
//Returns the quality factor of the resulting bandwidth
Examples: Demodulating Marker Values and Providing Audio Output
The following examples demonstrate how to demodulate markers and provide audio
output in a remote environment.
● Example: Providing Audio Output for Individual Marker Values..........................1207
● Example: Demodulating and Providing Audio Output Continuously................... 1207
Example: Providing Audio Output for Individual Marker Values
This example demonstrates how to demodulate markers and provide audio output in a
basic spectrum measurement in a remote environment. It assumes that the basic fre-
quency sweep described in Chapter 14.15.1, "Programming Example: Performing a
Basic Frequency Sweep", on page 1375 has been performed and thus does not begin
by presetting the instrument.
Audio output is provided for 5s each time the signal reaches its initial maximum, how-
ever only if it is higher than -90 dBm (10% of the total y-axis range) in order to ignore
noise.
//------------- Configuring the marker demodulation -------------------
CALC:MARK1 ON
//Activates marker1 and sets it to the maximum power level
CALC:MARK1:FUNC:DEM:SEL FM
//Selects FM demodulation
CALC:MARK1:FUNC:DEM:HOLD 5s
//Defines an output duration of 5s
DEM:SQU:LEV 10
//Sets a squelch level for noise
DEM:SQU ON
//Activates squelching
CALC:MARK1:FUNC:DEM ON
//Activates demodulation
//------- Performing the measurement -------------------------
INIT;*WAI
//Performs a measurement and waits for it to end
//---------------Retrieving Results-------------
//Results are only provided as audio output!
