4.2.5 Monitor operating mode

In the Monitor operating mode the MC-377+ works like a conventional television. In
addition, when the audio control
top of the image whose length corresponds to the level/power of the tuned signal.
Below this bar, superimposed on the middle top of the TV image, the line synchronism
pulse is shown with which it is possible to easily detect any possible saturation of the
amplifiers in terrestrial bands. The following figure shows the three types of information
appearing on-screen in the Monitor operating mode: demodulated television image (the
example shown in figure 6 shows a scale of greys), measurement bar (67 dBµV in
figure 6) and a representation of the line synchronism.
To better observe and identify the tuned channel, it is possible to eliminate the
measurement bar and the synchronism pulse by releasing the audio control

4.2.6 Taking measurements

The MC-377+ enables three different kinds of measurements to be taken:
Analogue signals level measurement
Digital channels power measurement
C/N ratio measurement of analogue and digital signals.
The following sections describe how to take each one of these measurements.
