Overview
The E5071C lets you perform power calibration by using a power meter to
output a more accurate power level.
Preparation for Power Calibration
Connecting Power Meter and Power Sensor
The E5071C performs power calibration by controlling the power meter via
GPIB. Therefore, you need to connect the E5071C and the power meter by
using the USB/GPIB interface.
Selecting the Power Meter
Use the following command to select the type of GPIB or USB enabled
power meter:
:SYST:COMM:PSENsor
Setting GPIB Address of Power Meter
Use the following command to set the GPIB address of the power meter to
the E5071C.
:SYST:COMM:GPIB:PMET:ADDR
Setting Power Sensor Calibration Factor Table
Before performing power calibration, set the reference calibration factor
(the calibration factor at 50 MHz) and the calibration factor for each
frequency depending on the power sensor you use.
• Depending on the combination of power meter and power
sensor that you use, the power sensor calibration factor table
may be set automatically by the power meter. In this case, do
not set the calibration factor table with the E5071C.
To set the reference calibration factor of the power sensor, use the
following commands:
