Fig. 6-1 The LEVEL Measurement Mode Screen
The following information is displayed in the Level measurement mode
screen (numbers correspond to callouts in Fig. 6-1):
1. Channel number or frequency
2. Channel label, video carrier frequency, and level dBmV (or dBuV—
this is a configuration parameter)
3. Audio carrier frequency in MHz and level
4. Delta between audio and video levels (dB)
5. Graphical display of carrier levels (dBmV)
6. Forward test point compensation (only if a non-zero value is
programmed during setup) compensates for the test point loss or
probe loss from the measurement result to show the signal level on
the system. (20.0 dB in this instance.)
Fig. 6-2 shows the display for tuning by frequency. With only a single
frequency involved, there is no Delta value. The display is a graphical view
of the Level measurement, referred to dBmV.
