Query only.
Unit returns the value of the measured frequency offset of the
carrier being demodulated. Values range from
100 Hz resolution.
Returns 999999 if the demodulator is unlocked.
Example: RFO=+002.3 (which is + 2.3 kHz)
Command or Query.
Rx acquisition sweep range of demodulator, in kHz, ranging
from 1 to 100 kHz.
Example: RSW=009 (selects
Demodulator Lock Status, where:
0 = Demodulator Unlocked
1 = Demodulator Locked
Example: DLK=1 ( Demodulator Locked)
Query Only.
Unit returns the value of the Rx signal level, in dBm, between
+3.0 and –99.0 dBm, where;
xxx is the Rx signal level.
Examples:
RSL=+03
RSL=-41
