the 1
st
IF frequency) as follows:
1) through the numerical keypad, press the
ENTER
key to confirm.
2) through the shaft encoder, turn it until you read the desired frequency on the screen.
The possible frequency steps (0.1 MHz or 4.0 MHz) are selected keeping the
FR
key
pressed and turning the shaft encoder to move the frequency cursor to corresponding units
or decimal number. Press
ENTER
to confirm.
When the instrument works on SCR mode the following functions remain active:
-
the usual functions of the spectrum analyzer;
-
LNB: to activate or deactivate the power-supply voltage of LNB SCR;
-
TV: to display analogue or digital pictures if MPEG4/MPEG2 module is installed;
-
MEA: to pass to MEASUREMENT mode.
-
DIGI: to activate the QPSK module to analyze the quality of digital satellite signal
with reading of BER, PVBER, MER and other parameters, as while using non-SCR
mode. Moreover, the activation of MPEG2 module enables the NIT reading and
display of pictures of free-to-air digital channels.
To exit SCR mode, press the
