//Returns the bandwidth at the specified power offset.
CALC:MARK:FUNC:NDBD:FREQ?
//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!
