5-4-5-10 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.
