BUC Current N/A 4 bytes Query only N/A BDC? BDC=xxxx
(L-Band Unit
only) Indicates the value of the BUC Current, in the form: xxxx, where: xxxx
is between 0 and 9999, units MA. (see description of
arguments)
If not available, response is 0000
Example: BDC=3100
BUC Voltage N/A 4 bytes Query only N/A BDV? BDV=xx.x
(L-Band Unit
only) Indicates the value of the BUC voltage, in the form: xx.x (see description of
arguments)
Where: xx.x is between 0 and 64.0
If not available, response is 00.0
Example: BDV=43.6 (BUC DC voltage is 43.6 volts)
