4-1 Power Meter Level Accuracy Power Meter Verification
4-2 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
Procedure Component Characterization:
1. Connect both MA2442D power sensors to the power meter and calibrate the sensors.
2. Connect the model 1870A power splitter to the MG3692A/B output, and connect Sensor B to one power
splitter output as shown in Figure 4-1 on page 4-1.
3. Install the 10 dB Fixed Attenuator to the other power splitter output, and then connect Sensor A to the
end of the Attenuator.
4. Set the power meter to display both Channel A and Channel B. Press the Sensor key, the Cal Factor soft
key, and then the Freq soft key. Use the keypad to enter the value matching the frequency of the
MG3692A/B as the input signal frequency, which sets the power meter to the proper power sensor
calibration factor. Repeat for Channel B. Press the System key to display the power reading.
5. Adjust the power level of the MG3692A/B to get a reading on Sensor A that matches the power level
(within ±0.1dB) in the first column of Table A-16, “Characterization Chart for Power Meter
Verification” on page A-14.
6. Record the Sensor B reading in the Required Sensor B Reading column of Table A-16.
7. Repeat Step 5 and Step 6 for the other power level in the first column of Table A-16, recording the
Sensor B reading in the second column.
8. Repeat Step 4 through Step 7 for the next input frequency.
