E4418B specific control codes are sent to the Agilent power meter via the RS-232 serial port in SCPI
format, so power meters that are not E4418B RS-232 SCPI compatible will not function with the
FireFox auto calibration procedure.
4.2.3 Calibrating the Power Sensor
The Agilent power meter has a Power Reference output that is used to calibrate the power sensor at
50MHz. Plug-in the 8482A power sensor into the
Power Ref
output of the power meter (see
Figure 4.1
). Press the ZERO/CAL button on the front of the power meter, and follow the instructions
in the LCD display to zero, and calibrate the sensor.
The power meter is now properly prepared. Agilent recommends to recalibrate the sensor every 24
hours, or if the ambient temperature changes.
4.3 Calibration Setup
Prior to starting the auto-calibration procedure, the user must connect the two instruments to each
other. Follow the procedures below to setup the calibration.
