CALC:DELT3:FUNC:BPOW:SPAN 30MHz
//Sets the bandwidth to be measured to 30 MHz
CALC:DELT3:FUNC:BPOW:MODE DENS
//Sets the result to be a density (power per Hz bandwidth)
//---------------Retrieving Results-------------
CALC:MARK1:FUNC:BPOW:RES?
//Returns the power sum for the specified bandwidth around marker 1.
CALC:DELT2:FUNC:BPOW:RES?
//Returns the power sum for the specified bandwidth around deltamarker 2.
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 11.15.1, "Programming Example: Performing a
Basic Frequency Sweep" , on page 1088 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 11.15.1, "Programming Example: Performing a
Basic Frequency Sweep" , on page 1088 has been performed and thus does not begin
by presetting the instrument.
