5-6 ISDB-T SFN Verification, Option 32 Option Verification
5-20 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
Level Accuracy Verification
The tests in this section verify the level accuracy of the MT821xE in ISDB-T SFN Signal Analyzer mode.
Setup
Procedure
1. Confirm that the Power Amplifier is Off.
2. Perform a Zero/Cal on Sensor A and Sensor B of the power meter. Set the calibration factor of both
sensors to 473 MHz.
3. Connect the MG3700A Signal Generator, Power Amplifier with N(f)-BNC(m) adapters, RF Limiter,
MN63A Programmable Attenuator, Power Divider, Power Meter, and Power Sensors as shown in
Figure 5-4.
4. On the MG3700A, press the Preset key (Yellow key on the upper left-hand side).
5. Press the Down Arrow key to select Yes.
6. Press the Set key.
7. Press the (F1) soft key to select “Load File to Memory”.
8. Press the (F1) soft key again to select “Select Package”.
