5 Command Reference
Power Measurement Subsystem
The Power Measurement Subsystem provides you the SCPI commands
reference for the HSA built in one button power measurement function,
such as Adjacent Channel Power Ratio ( ACPR ) , Channel Power (
CHP ) , Occupied Bandwidth ( OBW ) and Spectrum Emission Mask (
SEM ). Use the command :INSTrument:MEASure
OFF|CHPower|ACPR|OBW|SPECtrogram|SEM|CHScanner
to access different power measurement mode.
ACPR Subsection
Center Freq
[:SENSe]:ACPRatio:FREQuency:CENTer <freq>
[:SENSe]:ACPRatio:FREQuency:CENTer?
Sets the center frequency of the main channel power.
Range: 100.5 kHz to 6.9999995 GHz
Example: :ACPRatio:FREQuency:CENTer 3.4GHz
Key access: Meas > Center Freq
Main Channel
[:SENSe]:ACPRatio:BANDwidth|BWIDth:INTegration
<freq>
[:SENSe]:ACPRatio:BANDwidth|BWIDth:INTegration?
Specifies the range of integration used in calculating the power in the
main channel.
*RST: 1 MHz
Range: 300 Hz to 25 MHz
Example: :ACPRatio:BAND:INTegration 2 MHz
Key access: Meas > Main Channel
