Signal level measurement mode tuned by frequency is shown in Figure 4.3.7.
In this mode neither the digital D, analogue V/A ratio or C/N ratio indicators
In the signal level measurement mode, a signal level is measured at the tuned
frequency. This mode is indicated by a Hz message in the command line. Tuning by
frequency is performed in 125 kHz steps by ◄ and ► arrow keys.
By toggling the F2 key you have the option to measure by Hz or Ch
To control AMP power supply, enable the corresponding mode by briefly pressing the

1 – Channel number indicated by marker
2 – Command line with commands activated by F1, F2 and F3 keys
3 – Channel name (when working with selected channel plan)
4 – Measured level of channel indicated by marker, in dBmV, dB V or dBm
5 – Status of AMP power supply (Section 4.3.8)
6 – Marker
7 – Channel status: A – analog, D - digital.
You can navigate the marker by means of ◄ and ► keys.
If no channel plan has been selected, all the channels of the standard channel
allocation will be displayed on the screen. Channel modulation type is determined
automatically when you enter the mode and each time the signal is connected to the input.
It is shown by the progress indicator «channels scanning». The modulation type of the
