AVM-510A Option T (For Transmission Monitoring)
11-6
To select the differential phase function:
1.
Set the center of the lowest point on the waveform to zero.
2.
View the center of the peak and calculate the difference in IRE/%.
3.
Calculate the differential phase as listed in the following table or use 0.573
°
/IRE if the reading is
under 20 IRE. The graticule in the IRE correlation-to-phase is 0.573
°
per IRE between 0 and 20
IRE.

ICPM
The ICPM mode lets you monitor the phasing of the transmitter usint the I and Q signals from a
broadcast quality demodulator. Two different resolutions are available for ICPM montoring. One is at
2
°
/division accessed by factory default memory 9 and the other is at 6
°
/division accessed by factory
default memory 10.
The 4 horizontal lines starting from the top correspond to the zero carrier, 100IRE (or % in PAL),
blanking, and sync levels of video. All are provided for calibration refferences.
