2.4.1 Receive IF Carrier Acquisition Range
The terminal will automatically lock to a correctly formatted carrier, which is within
35 kHz of the display receive frequency.
2.4.2 AGC Output (IDU)
A programmable DC output, proportional to the IDU receive signal level is located at the
rear of the panel at 10 mA maximum, 0 to 10V. Default levels are 0v for minimum signal
condition, and 10V for maximum signal condition. The low level can be programmable
from 10 to 0V in 0.1V increments.
