1.1 Description

The MC-377+ is a compact, light-weight, portable instrument which offers installers
all the basic functions needed to guarantee the good operation of analogue and digital
TV installations.
The instrument covers television bands, hyperband, cable television S channels
as well as the satellite intermediate frequency band in K/C, up to 2050 MHz.
The MC-377+ has two main operation modes: Monitor mode and Spectrum
Analyser mode:
The Spectrum Analyser mode enables all the signals present in a band to be
viewed on the monitor. The bandwidth represented in the spectrum mode can be
selected as either the complete band or a bandwidth defined by the user (from
approximately 1/3 of the band in use to almost zero).
In the Monitor mode the instrument demodulates the analogue TV signal, which
enables a terrestrial or satellite television channel to be identified and its reception
observed. The signal level in monitor mode is represented by an analogue bar at the
top of the image whose length varies in proportion to the power received. In addition it
enables the line synchronism pulse to be observed, overlaid on the top centre of the
screen.
The MC-377+ enables you to easily take the following measurements: analogue
signal levels, digital channel power and Carrier to Noise ratio (C/N) in analogue and
digital channels.
The instrument can also supply the voltage needed to power external units: aerial
pre-amplifiers and LNBs with 13 or 18 V, together with a 22 kHz signal superimposed
onto the voltage for the commutation of polarisation, band or signal switches.
A SCART connector has been also included with input/output of audio/video.
