TX Power Supply Management
The TX Power supply has two separate voltage outputs, as follows:
•
TX Power Supply #1 (TX1)
- generates voltage levels for pulsed TX operations
•
TX Power Supply #2 (TX2)
- generates voltage levels for both pulsed and CW operations
The RFI sets the voltage level for the two TX Power Supply outputs (
TX1
and
TX2
) and also measures
the voltage levels and current drain from the two TX outputs. If any of the values
exceed
the limit for a
given mode, the RFI will turn OFF power to the probe.
