Troubleshooting Manual

.

The exciter/control stage performs many critical functions for the transmitter. The primary 
component of this stage is the exciter/control PWB (A1).

The exciter portion of the exciter/control PWB performs the following functions:

•

accepts the audio inputs and generates the RF drive signal required to modulate the audio 
signal at the desired carrier frequency.

•

measures the audio input level.

•

provides the status of any exciter fault conditions.

The control portion of the exciter/control PWB performs the following functions:

•

contains monitoring and protection circuits to prevent transmitter damage under adverse or 
fault conditions, including high speed SWR protection and interlock/muting.

•

monitors the current value of various parameters including cooling fan tachometer outputs, 
transmitter output forward and reflected power, PA temperature, PA current levels, and PA 
power supply status signals.

•

measures and monitors the the output voltage from the power supply module as well as the 
low voltage supplies (+15 V and +5 V) and +48 V power supply.

•

generates the dc bias signals for the pre-amp and PA PWBs.

•

generates the signals that enable the power supply module and control its output voltage.

•

provides the status of any controller fault conditions.

•

an integral DSP performs all audio processing including filtering and FM baseband 
modulation.

•

interfaces with the RF and power supply sections of the transmitter to perform control and 
monitoring functions.
