Command or Query
Sets or returns valid Operating RF frequency, in MHz.
For Ku BDCs:
FRE values: 10950-11700 MHz an LO of 10000 MHz is activated
FRE values: 11701-12250 MHz an LO of 10700 MHz is activated
FRE values: 12251-12750 MHz an LO of 11300 MHz is activated
Example: FRE=11300.000

6 bytes, numeric Query only.
Returns the LNA/LNB Current Source Level in mA in the form s_xxx.x,
where:
s=1 (LNA A) or 2 (Bias Tee)
xxx.x= LNA Current Source Level in mA
Example:
<0001/LCM?2

Sets or returns LNA Current Source Enable in the form sx, where:
s=1 (LNA A AUX COMM) or 2 (LNB Bias Tee)
x=0 (Disable) or 1 (Enable)
Example: LCS=20 (turns off the LNB Bias Tee current)

numeric
Command or Query.
This command allows the user to set the alarm window in ± % of the
calibrated LNA/LNB Bias Current in the form sxx, where:
s=1 (LNA A AUX COMM) or 2 (LNB Bias Tee)
xx=Valid inputs are 20 to 50 in increments of 1%. Setting the value to 99
disables the alarm function.
Default is Disabled.
Example: LCW=230 sets alarm window for LNB Bias Tee to ± 30%.
