Terrestrial band - Analogue channels:
Level Level measurement of the currently tuned carrier.
C/N Video carrier to noise ratio referenced to a noise frequency
defined by the user through the Reference Noise function.
Terrestrial band - Digital channels:
Channel power Integration method. It consists of scanning the entire
channel, calculating the contribution of each portion of the
spectrum to the whole.
C/N Referenced: Channel level to noise ratio referenced to a
noise frequency defined by the user through the Reference
Noise function.
Satellite band - Analogue channels:
Level Level measurement of the currently tuned carrier.
C/N Video carrier to noise ratio referenced to a noise frequency
defined by the user through the Reference Noise function.
Satellite band - Digital channels
Channel power Integration method.
C/N Referenced: Channel level to noise ratio referenced to a
noise frequency defined by the user through the Reference
Noise function.
Like in the TV mode, to select the type of measure, press key [22] then
turn the rotary selector [4] until desired mode is marked and finally press the rotary
selector [4] or key [22] to activate the new measurement mode.
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.
4.10.2.2 Measuring the Carrier / Noise ratio (C/N Referenced)
The Carrier/Noise ratio in Spectrum mode is always referenced to a noise
frequency defined by the user.
