13. Press the Set key.
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 the “MS63A Attenuation Reading AT(–10)” column of Table A-130, “Readings for
Sensor A, Sensor B, DAB(–10), and MN63A Attenuation AT(–10), Option 64” on page A-41.
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 in Table A-130:
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 the “DAB (–10)” column of Table A-130.
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-133, “DVB-T/H Signal Analyzer Level Accuracy Measurement
Channel = 21ch at 474 MHz, Option 64” on page A-42.
