11. AVM-510A Option T
(For Transmission Monitoring)
Introduction (AVM-510A-T)
This chapter describes the following functions added to the AVM-510A in the option T:
•
Transmiter measurement set using zero carrier reference
•
1H line sweep of differential gain and differential phase
•
Incidental Carrier Phase Modulation (ICPM) display of transmitter phasing from I and Q outputs
of a broadcast quality demodulator
Transmitter Measurement Set
This section describes the following components in the transmitter measurement set:
•
Zero carrier
•
Measure line
•
Measure signal ID
Zero Carrier
In the transmitter measurement set, the measurements for PEAK VIDEO, WHITE BAR, and
BLANKING LEVEL are all referenced to a zero carrier reference pulse (see Figure 11-1). This
reference pulse must be in the vertical interval on any horizontal line from 9 to 25, inclusive.
