4.10.2 Selecting the Measurement Mode
The Spectrum Analyser mode permits to make different measurements at the
same time you see the signals present in the band. The types of measurements
available are:
Terrestrial band - Analogue channels:
Level
C/N
Terrestrial band - Digital channels:
Channel power
C/N
Satellite band - Analogue channels:
Level
C/N
Satellite band - Digital channels
Channel power
C/N
Like in the TV mode, to select the type of measure, press key
turn the rotary selector [4] until desired mode is marked and finally press the rotary
selector [4] or key
4.10.2.1
Measuring Carrier Levels (Level)
(Only for analogue channels). When selecting this mode on the lower part of the
image appears the tuned frequency (or channel) and the signal level at this frequency. If
dual marker function is selected, tuned frequency and signal level are showed for each one
of the markers and, on the far right, the frequency difference and the level between them.

Level measurement of the currently tuned carrier.
Video carrier to noise ratio referenced to a noise frequency
defined by the user through the Reference Noise function.
Integration method. It consists of scanning the entire
channel, calculating the contribution of each portion of the
spectrum to the whole.
