3.2.7 Sense Subsystem Commands
The SENSe subsystem configuration commands, illustrated in Figure 3-4, apply to individual sensors. These
commands alter the value of the measured power level according to the sensor’s characteristics. For example,
measured power levels can be offset for attenuators or couplers in the measurement path so that the power
data reading reflects the power level at the measurement point of interest.
Use the SENSe subsystem commands for:
• Averaging power measurements in the 8650B
• Offsetting power measurements for attenuation or amplification
• Entering the operating frequency of the measured signal computes and applies sensor specific Calibration
Factor corrections, which compensates for sensor frequency response characteristics
• Controlling Peak Power Sensor triggering
• Controlling Modulation Power Sensors
SENSe subsystem commands control functions that are related directly to the individual power sensors. For
example, these commands control items that would not apply to numerical alteration of a ratio measurement of
Sensor1/Sensor2. Controls that would apply to that type of a configuration are channel functions, not sensor
functions, and would therefore be located in the CALCulate subsystem.

SENSe:AVERage functions control the number of data samples for each measurement and the manner in which
those numbers are accumulated. COUNt determines the averaging number or AUTOaveraging. TCONtrol
determines whether each new sample is added to previous COUNt # of samples or if COUNt # of samples are
