5-16 DVB-T/H Signal Analyzer Verification, Options 64 and 57 Option Verification
5-82 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
14. Use the Down Arrow key to step through the selection list until the DVB-T_H_00 option is highlighted.
15. Press the Set key.
16. Perform a Zero/Cal on Sensor A and Sensor B on the power meter. Set the calibration factor of both
sensors to 474 MHz.
17. Set the MG3700A Frequency to 474 MHz.
18. Set the Level to –25 dBm.
19. Ensure that the Mod On/Off key and the Output key each have an illuminated LED.
20. Turn On the power amplifier and allow it to warm up for at least 5 minutes.
21. Adjust the MN63A Attenuator so that the Sensor A reading is –10 dBm ± 1 dBm. Record the actual
attenuation reading in Table A-73, “Option 64, DVB-T/H Signal Analyzer, Level Accuracy Verification,
–10” on page A-46
22. On the MG3700A, adjust the power level so that the Power Meter Sensor A reading
is –10.0 dBm ± 0.2 dBm.
23. Record the following values to the appropriate table cells inTable A-73:
Power Meter Sensor A reading to “Sensor A Reading”
Power Meter Sensor B reading to “Sensor B Reading”
24. Subtract the value of the Sensor A reading from the value of the Sensor B reading and record the result to
the “DAB (–10)” column of Table A-73
25. Calculate the AT(set) values for Test Levels –10 dBm through –45 dBm and record the values in the
“AT(set) (dB)” column in Table A-75, “Option 64, DVB-T/H Signal Analyzer, Level Accuracy
Measurement, Channel = 21 at 474 MHz” on page A-47
