Option Verification 5-16 DVB-T/H Signal Analyzer Verification, Options 64 and 57
MT8212E and MT8213E MM PN: 10580-00255 Rev. J 5-83
26. Remove Sensor A from the Power Splitter, and then connect the Power Splitter to the Cell Master RF In
port with the N(m)-to-N(m) adapter, as shown in Figure 5-16.
27. Record the new Power Meter Sensor B reading into the “SB(–10)” box in Table A-75, “Option 64,
DVB-T/H Signal Analyzer, Level Accuracy Measurement, Channel = 21 at 474 MHz” on page A-47.
28. On the Cell Master, set the mode to DVB-T/H Signal Analyzer and preset the instrument.
29. Press the Frequency main menu key, then the Signal Standard soft key and choose Digital Terrestrial TV
UHF (Europe). Ensure that Channel 21 is selected and that the Pre Amp is Off.
30. Change the Reference Level to –10 dBm.
31. Press the Shift and Sweep (3) hard keys, then press Meas Mode.
32. Use the Up/Down Arrow keys to highlight Moving Average, and press the Enter key.
33. Change the Average Count to 50, if required.
34. After Average (50/50) appears at the top of the display, record the Channel Power from the Cell Master to
the “Pre Amp Off M(Level) (dBm)” column in Table A-75.
35. Calculate the Deviation by using the following formula:
Deviation = M(Level) – SB(–10) – ΔAB(–10) – AT(–10) + AT(set)
Figure 5-16. Level Accuracy Verification
Note Because AT(–10) is the same as AT(set), the value of [–AT(–10) + AT(set)] is equal to zero.
