RX Frequency Offset N/A 6 bytes Query Only
Unit returns the value of the measured frequency offset of the
carrier being demodulated, in the form sxxx.x, where:
xxx.x=value (range from 0 to 200 kHz, 100 Hz resolution)
R999.9 if the demodulator is unlocked
Example: RFO=+002.3 (2.3 kHz) N/A RFO? RFO=sxxx.x
(see description of
arguments)
Buffer Fill State N/A 2 bytes Query only
Unit returns the value of the buffer fill state, between 1 to 99%
Returns 00 if demodulator is unlocked
Example: BFS=33 (33%) N/A BFS? BFS=xx
(see description of
arguments)
Temperature of
Modulator N/A 3 bytes Query only
It returns the value of the internal card temperature, in the form of
sxx (degrees C)
s=sign (+ or – character)
xx=value
Example: TMP=+26 N/A TMP? TMP=sxx
(see description of
arguments)
Temperature of the
Base Unit N/A 3 bytes Query only
Unit returns the value of the internal base unit temperature, in the
form of sxx (degrees C)
s=sign (+ or – character)
xx=value
Example: ITP=+26 N/A ITP? ITP=sxx
