Performance Verification 2 3-13 DVB-T/H Signal Analyzer (Options 64 and 57) Verification
MS2721B MM PN: 10580-00177 Rev. D 3-87
4. Connect the MG3700A Signal Generator, Power Amplifier with N(f)-to-BNC(m) Adapters, RF Limiter,
MN63A Programmable Attenuator, Power Divider, Power Meter, and Power Sensors as shown in
Figure 3-23.
5. On the MG3700A, press the MOD On/Off button to turn off Modulation, and verify that the MOD On/Off
LED is OFF (not illuminated).
6. Set the Level output of the MG3700A to –25 dBm.
7. Set the MN63A attenuation to 20 dB.
8. Turn on the power amplifier and allow it to warm up at least 5 minutes.
474 MHz Tests
9. Set the calibration factor of both sensors to 474 MHz.
10. Set the MG3700A Frequency to 474 MHz.
11. Adjust the MN63A attenuation so that the Power Meter Sensor A reading is –25 dBm ± 1 dBm. Record
the MN63A attenuation readout in Table A-132, “Readings for Sensor A and MN63A Attenuation
AT(–25), AT(–15), AT(–50), and AT(–43), Option 64” on page A-41.
12. Adjust the Level of the MG3700A so that the Power Meter Sensor A reads –25.0 dBm ± 0.05 dBm. Record
the Sensor A reading to the M(Sa) column in Table A-132.
13. Remove Sensor A from the splitter and connect the MS2721B RF In port to the open end of the splitter
using an adapter as shown in Figure 3-24.
