Digital Mode

In this mode, you can make two types of measurements. To switch between
them, you must press the rotary knob. The measurements are:
- Input Channel Power
The digital mode shows the power level of the input channel. It is represented
by a bar graph and in numeric value (dBµV). It also measures the BW (bandwidth) and
the C/N ratio (carrier / noise).
- Constellation Diagram
In this mode is shown the Constellation Diagram and other related measures
(Fig. 32).
- QAM modulation type.
- Encoding type detected.
- Symbol rate (SR).
- Error rate obtained for the Post-BER digital signal (BER after FEC) indicated
by BER
- Error rate obtained for the Pre-BER digital signal (BER before FEC) indicated
by BER.
- Error rate of modulation (MER).
- Quadrant shown
- Locked / Unlocked
To switch to the Input Channel Power, press fast and twice the rotary knob.
