Response to
Query
Rx Signal Level N/
A
4 bytes Query Only.
Unit returns the value of the Rx signal level, in dBm, between –5 and –99 dBm, in
the form ccxx, where:
cc = code (GT=Greater Than; LT=Less Than, == is ‘equal to’)
xx = value (the ‘-‘ sign is implied)
Examples:
RSL=LT99 (Rx signal level is less than -99 dBm)
RSL===41 (Rx signal level is equal to -41 dBm)
