Side Board

The side board is mounted on the side plate. It performs these functions:
• Provides the 1 MHz reference clock for the RF amplifier.
• Generates the RF component of the voltage applied to the quadrupole mass
• Generates the DC component of the voltage applied to the quadrupole mass
• Passes voltages generated on the main board and the detector focus voltage
• Generates and adjusts filament emission current and electron energy as
• Switches the filament power from one filament to the other.
• Monitors for RF faults and shuts down the analyzer if one is detected.
