PRELIMINARY
Calibrating the Gigatronics
8541C Power Meter
Precise transmit Output Power Calibration measurements are made using
a Bolometer–type Broadband Power Meter with a sensitive Power
Sensor. Perform the procedure in Table F-22 to enter information unique
to the Power Sensor.
Table F-22: Gigatronics 8541C Power Meter Calibration Procedure
n Step Action
! CAUTION
Do not connect/disconnect the Power Meter Sensor Cable while AC Power is applied to the meter.
Disconnection could result in destruction of the Sensing Element or miscalibration.
1 Make sure the Power Meter POWER Pushbutton is OFF.
3 Connect the Power Sensor Cable to the SENSOR Input.
4
Set the POWER Pushbutton to ON.
NOTE
Allow the Power Meter and sensor to warm–up and stabilize for a minimum of 60 minutes before
performing the Calibration Procedure.
5 Connect the Power Sensor to the CALIBRATOR Output Connector.
6 Press ZERO.
Wait for the process to complete.
Sensor Factory Calibration Data is read to Power Meter during this process.
7 When the Zeroing Process is complete, disconnect the Power Sensor from the CALIBRATOR
Output.
