Power Sensor Calibration Factor Entry
5. Press
to access the calibration factor menu for power sensor A.
6. Build a table of up to 55 points (55 frequencies with their calibration factors). To enter
each point, follow these steps:
a. Press .
b. Input a frequency value and then press the appropriate key ( , , or ).
c. Press and enter the calibration factor percentage that corresponds to
the frequency you entered.
The cal factor and frequency values are found on the back of the sensor. If you make
a mistake, press and re-enter the correct value.
d. Press to complete the data entry for each point.
NOTE The following terms are part of the sensor calibration menu.
7. For Option 006 Instruments Only: Press to create a
power sensor calibration table for power sensor B (8481A), using the softkeys
mentioned previously. Since sensor B is only used for 3 GHz to 6 GHz measurements,
you only need to input calibration factors for this frequency range.
8. Zero and calibrate the power meter and power sensor.
Update Sampler Correction Constants
9. Preset, zero, and calibrate the power meter and 8482A (sensor A).
10.Press .
11.Connect the equipment as shown in Figure 3-6.
