5.3.16 STHRESHOLD Control Signal Thresholds

This command controls signal acquisition and steady-state-lock signal thresholds. The sigchan, acqui, lock and
crosscorr fields must have values. They set the thresholds for the specified signal channel.
See also on Page 122 for the mapping of signal channels.
