LNB LO
Frequency
(L-Band Unit
only)
LLO= 6 bytes Command or Query
LNB Receive LO frequency information in the form: xxxxxx,
where: xxxxxx is the LO frequency, in the range of 3000 to
65000 MHz.
All 0’s (000000) disables this feature.
s is the sign for the mix (+ or – character)
Terminal Frequency = LNB LO RFQ
Example: LLO=06000- (LO is 6 GHz, high-side mix)

LNB Current
(L-Band Unit
only)
N/A 3 bytes Query only.
Indicates the value of the LNB Current, in the form: xxx, where
xxx is between 0 and 999, units mA.
If not available, response is 000.
Example: LDC=210 (LNB DC current is 210 mA)
N/A LDC? LDC=xxx
(see description of
arguments)
LNB Voltage
(L-Band Unit
only)
N/A 4 bytes Query only.
Indicates the value of the LNB Voltage, in the form: xx.x, where
xx.x is between 0 and 20.0
If not available, response is 00.0
Example: LDV=18.1 (LNB DC voltage is 18.1 volts)
N/A LDV? LDV=xx.x
(see description of
arguments)
Terminal Rx
Frequency
(L-Band Unit
only)
N/A 10 bytes Query only.
Terminal Rx Frequency, where frequency = LNB LO ± RFQ
Resolution = 100Hz
Returns 00000.0000 if LNB LO is zero
Example: TRF=11650.2249
N/A TRF? TRF=xxxxx.xxxx
(see description of
arguments)
