11. Press the Amplitude soft key and then press the Reference Level soft key.
12. Use the keypad to enter 10 and press the dBm soft key.
13. Press the Atten Lvl soft key and enter 30, then press the dB soft key.
14. Adjust the source power so that the power meter displays the corresponding desired Sensor B reading as
recorded for 0 dBm in the Required Sensor B Reading column of Table A-5.
15. Press the Marker soft key and press the Peak Search soft key.
16. Record the Marker 1 amplitude reading in the 0dBm row of Table A-6, “Spectrum Analyzer 50 MHz
Absolute Amplitude Accuracy”.
17. Verify that the Marker 1 amplitude reading is within the specification.
18. Repeat Step 14 through Step 17 for the other power level settings. Refer to Table A-5 for Required
Sensor B Readings. Use Table A-6 to record test results. The last two power level settings are with the
pre-amp turned on, to ensure pre-amp functionality.
Amplitude Accuracy Across Frequency Verification
This procedure is the second test used to verify the absolute amplitude accuracy of the Spectrum Analyzer in
the S332E or S362E Site Master. The first procedure test was described above in “50 MHz Amplitude Accuracy
Verification” on page 2-7.
