Canceller Operation
The round-trip time is used to calculate the time offset between the Local TX signal and the
RX data containing the Near TX signal. The more accurately the earth station
latitude/longitude, and satellite longitude configuration, or actual round trip delay
parameters are entered, the faster the acquisition time will be. After initial acquisition, a
continuous 24-hour period is required for the software to determine and store an accurate
round-trip time. If using delay, check the canceller delay graphs to ensure the maximum
and minimum excursions accurately match the entered delay parameters. If need be, the
round-trip delay parameters can be honed to ensure optimum performance.
