The rf voltage generation electronic assemblies include the following components:
• RF oscillator
• RF Voltage Amplifier PCB
• Low Pass Filter PCB
• RF voltage coil
• RF voltage detector
• Mass DAC
• Integrating amplifier
The ion detection system electronic assemblies provide high voltage to the electron multiplier
and conversion dynode of the ion detection system. They also receive the electron multiplier
output current signal, convert it to a voltage (by the electrometer circuit), and pass it to the
embedded computer.
The ion detection system electronic assemblies include the following:
• Electron multiplier power supply
• Conversion dynode power supply
• Electrometer PCB
• Acquisition DSP
The Analyzer Control PCB contains circuitry for controlling and monitoring the operation of
the ion source, ion optics, mass analyzer, and ion detection system. These circuits are in turn
monitored by the PowerPC processor of the System Control PCB via the SPI bus.
The Analyzer Control PCB controls and monitors the rf voltages for Q0, Q1, Q2, and Q3
quadrupoles. It also has lens voltage drivers that convert ±330 V dc power from the DC Rod
Driver PCB to dc voltages that are applied to the lenses.
The data system controls and monitors the TSQ mass spectrometer. The data system also
processes data that the TSQ mass spectrometer acquires. The data system is composed of the
following:
• Computer Hardware
• Data System / Mass Spectrometer / LC Communication, Contact Closure, and Line
Power Connections
• Data System / Local Area Network Interface
