Spectrum Analyzer Verification 2-5 Spectrum Analyzer Absolute Amplitude Accuracy Verification
S3xxE MM PN: 10580-00253 Rev. J 2-13
9. Set the power meter to display 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 MG3692x as the input signal
frequency, which sets the power meter to the proper power sensor cal factor. Press the System key to
display the power reading.
10. Set the MG3692x frequency to 10.1 MHz CW.
11. Adjust the MG3692x output power so the power meter displays a reading that matches the Sensor B
reading for –50 dBm in Table A-7.
12. On the S3xxE, press the Marker key and press the Peak Search soft key.
13. Record the Marker 1 amplitude reading in Table A-8, “Spectrum Analyzer Absolute Amplitude Accuracy
Across Frequency”.
14. Verify that the Marker 1 amplitude reading is within the specification.
15. Repeat Step 6 through Step 14 for other frequencies, input power, reference level, attenuation and
pre-amp settings in Table A-8.
