for Command
(Note that all arguments are ASCII numeric codes from 48 to 57)
or Query
1 byte Command or Query.
Sets or returns Rx Spectrum Invert, where:
0 = Normal
1 = Rx Spectrum Invert
Example: <0001/RSI=0{CR} (selects Normal)
5 bytes Query only.
Returns the value of the Rx signal level in the form sxx.x, where:
s = sign (+/–)
xx.x = Rx signal level value, in dBm, from +15.0 to –60.0 dBm
Example 1: >0001/RSL=+15.0{CR}{LF}
Example 2: >0001/RSL=–60.0{CR}{LF}
Note: Unit returns ∀99.9 if unit returns value beyond limits.
Example 3: >0001/RSL=+99.9{CR}{LF} (RSL >+15.0 dBm)
Example 4: >0001/RSL=–99.9{CR}{LF} (RSL <–60.0 dBm)
8 bytes Command or Query.
Sets or returns the Rx acquisition sweep range of the demodulator in
the form xxxx.xxx, where:
xxxx.xxx = value, in kHz, ranging from 0 to 60 kHz.
Example: <0001/RSW=0060.000{CR} (selects 60 kHz)
