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

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%.
