MEASUREMENT
Connect the signal to be measured to the input connector
RF IN (5)
PLEASE NOTE: an input voltage higher than the maximum limit value (100
V DC or
\5 Vpp) may damage the instrument.
Do not supply input DC when the LNB is powered.
Select the measurement function pressing the
MEA
key.
Fix the measurement unit.
Select analogue or digital mode of carrier to be measured, pressing the
2nd
key and then
the
D/A
key. The measure indicator on status bar changes from “LEV” (measure of
analogue level) to “POW” (measure of digital carriers).
Set the proper demodulator according to the kind of signal to be measured: TV for analogue
TV video carriers, FM for Frequency Modulation carriers, AM for Amplitude Modulation
carriers.
The instrument displays the following information:
•
the signal level in numerical format;
•
the related analogue level by bargraph;
•
TV picture (partial), if the TV demodulator is selected;
•
Waveform of TV line synch.
In audio:
•
Acoustic indicator of level, if activated.
