The IntracAction Model GE series high power acousto-optic modulator drivers include a crystal-controlled RF oscillator, fast modulation circuit, and a broadband RF power amplifier in a housing with power supply, RFI line filter, line switch, and fault/interlock circuit. The standard crystal controlled oscillator has a calibration tolerance of 25 ppm. Crystals at other than the specified frequencies can be factory installed. The standard modulation input configuration is analogue with a digital input option available.
A CW RF output level is adjusted by the front panel level control which inserts a dc offset to the input of the modulation circuit with no modulation input voltage. The class AB broadband amplifier has sufficient bandwidth for pulsed operation. RF output power capability can be up to 100 watts for some models. Configuration options include a front panel user-accessible connection between the oscillator and modulation circuit (H) so that an external source frequency can be used in place of the internal crystal oscillator.
Also available is an optional front panel connection between the modulation circuit and the RF power amplifier (N) to give the Model GE drivers capability to be used as a stand-alone RF power amplifier. The fault/interlock circuit will latch the power supply off when an open circuit condition is present and can be connected to the thermal switch of a Germanium infrared modulator or in a normally closed system interlock circuit.
