CALC:DELT3:FUNC:BPOW:RES?
//Returns the power sum for the specified bandwidth around deltamarker 3.
Example: Measuring Characteristic Bandwidths (Using the n dB Down Marker)
This example demonstrates how to measure a characteristic bandwidth using markers
in a basic spectrum measurement in a remote environment. It assumes that the basic
frequency sweep described in Chapter 14.15.1, "Programming Example: Performing a
Basic Frequency Sweep", on page 1199 has been performed and thus does not begin
by presetting the instrument.
//------------- Configuring the n dB down marker -------------------
CALC:MARK1 ON
//Activates marker1 and sets it to the maximum power level
CALC:MARK1:FUNC:NDBD 3DB
//Sets the level offset to 3 dB
CALC:MARK1:FUNC:NDBD:STAT ON
//Activates the n dB down measurement
//---------------Retrieving Results-------------
CALC:MARK:FUNC:NDBD:RES?
//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
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 1199 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
