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)
Query only.
Rx Symbol rate, in ksymbols/sec, between 4.8 ksps and 3.00 Msps Resolution = 1
sps.
Example: RSR=2047.999 (2047.999 ksymbols/sec)
Command or Query.
Rx ± acquisition sweep range of demodulator, in kHz, ranging from ± 1 to
± 32 kHz (rates < 625 ksym/second) or
± 1 to ± 200 kHz (rates >= 625 ksym/second) CDM-570L only
Example: RSW=009 (selects ± 9 kHz)
