Menu Bar

The Menu Bar contains the following menus:

File Menu

The File menu contains the Exit command, which terminates the application.

Tools Menu

The Tools menu contains:

• Reset Averages: Restarts the averaging.

• Clear Fixed Offset: Removes the offset value and displays the absolute power being measured at 

the sensor’s RF input port.

• High Aperture Time: When High Aperture Time mode is selected, the sensor provides more 

accurate measurements of TDMA signals. In this mode, the ADC acquisition time is increased and 
the display update rate is decreased. This mode can be useful when measuring low power, 
modulated signals, and when changing between ranges.

• Upgrade Firmware: Launches the firmware upgrade sequence. Refer to Appendix C for a 

procedure on upgrading the firmware.

• Connected to COM Port Number: Displays the COM port number that is currently assigned to 

the power sensor.
