This section shows an example of executing power calibration using the E4418B power meter and the E4412A power sensor.
Power calibration may not be executed when the specified frequency and level is out of range of the power sensor specification.
In this example, power calibration is executed according to the steps shown in table below.
|
Step |
Description |
|
Connects the power meter to the E5071C. |
|
|
Configures the power meter's USB/GPIB interface and GPIB address with the E5071C. |
|
|
Sets conditions such as the power level and frequency. |
|
|
4. Executing Zero Adjustment and Calibration of Power Sensor |
Executes zero adjustment and calibration of the power sensor. |
|
Selects the port, selects the power sensor, sets the number of measurements at one point, and sets the tolerance during power calibration. |
|
|
Connects the power sensor. |
|
|
Executes the measurement of calibration data. |
Connect the GPIB connector on the E4418B (GPIB address: 14) to the E5071C through USB/GPIB Interface.
From Firmware revision 9.2, E5071C supports USB enabled power sensors. When you connect USB enabled power sensor for the first time, new hardware wizard runs. For more information, refer to Setting system controller (USB/GPIB interface)
