PLEASE NOTE
: some program may be not broadcast as declared, so the corresponding
line may be green when the signal is encrypted instead, or vice versa.
9.2.2. Program display
Highlight the line of the desired program through the shaft encoder, then press
ENTER
or
the
TV
key.
Do the same to select a radio program.
The MPEG module takes a few seconds to select the chosen program among those available
and to decode it before displaying it.

NOISE GENERATOR
10.1.
Introduction
Noise, spreading by nature over a wide spectrum range, may be helpful, in some cases, as
a substitute of expensive wide-range frequency generators. The most frequent applications
of the noise generator are: calibration of channel amplifiers, check of standing waves,
impedance, integrity of coaxial cables.
PLEASE NOTE
: The NG96A, due to its high output power (approx. 1 mW), may easily
saturate the input stages of the measuring instruments; therefore it is necessary to
check this does not occur and, if required, to place a proper attenuator at the input
of the measuring device.
10.2.
Use
The signal of noise generator, when this is activated, is present at the
NG OUT
connector.
To activate and deactivate the generator press keys
2nd
+
NG
or keep the
MENU
key
pressed for long; in this way the “MAIN MENU” appears. Under NOISE GENERATOR, its
status (ON or OFF) is indicated. Once the item has been selected through the shaft
encoder, press
ENTER
and select the desired status through the shaft encoder; press
ENTER
to confirm selection.
To exit the Main Menu, press
MENU
or select EXIT through the shaft encoder and press
ENTER
.
