Calibrating Gigatronics 8541C Power Meter
Precise transmit output power calibration measurements are made using
a bolometer-type broadband power meter with a sensitive power sensor.
Follow the steps in Table F-19 to enter information unique to the power
sensor.

Step Action
1
! CAUTION
Do not connect/disconnect the power meter sensor cable with AC power applied to the meter.
Disconnection could result in destruction of the sensing element or miscalibration.
Make sure the power meter POWER pushbutton is OFF.
2 Connect the power sensor cable to the SENSOR input.
3
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.
4 Connect the power sensor to the CALIBRATOR output connector.
5 Press ZERO.
- Wait for the process to complete. Sensor factory calibration data is read to power meter during this
process.
6 When the zeroing process is complete, disconnect the power sensor from the CALIBRATOR output.
