Circuit Descriptions
Bipolar Display
The Bipolar Display board is the numeric display for the mode's power set
point, and the signals for these indicators derive from the multiplexed
display driver on the Monopolar Control/Display board. The Bipolar
Display board displays the bipolar RF indicator and the RF circuitry
generates the signals.
An audio alarm is also present on this board. Circuitry on the
Microprocessor board performs the frequency select for the alarm. A
potentiometer on the rear panel controls the volume. In the case of an
alarm condition, the board bypasses the volume potentiometer and a full
volume alarm sounds. The Monopolar Control/Display board contains
this circuitry.
Monopolar Control/Display
The Monopolar Control/Display board (also known as the CPU board)
has two major functions:
• Serve as the main control element of the generator
• Provide the user interface.
As part of its control function, the CPU board supports REM monitoring.
The board also supports adaptive REM monitoring, but only when RF is
inactive.
When functioning as the operator/generator interface, the CPU board
receives all operator keyboard inputs and performs the proper functional
response (e.g., increment power register and display, change mode, and so
forth). Further, it accepts all activation signals after the Interface board
decodes them and performs the necessary steps to produce the desired RF
output.
