IntraAction ME Series Modulator Driver
Electronics designed to drive an IntraAction acousto-optic modulator. 30 nsec rise time.
The IntraAction Model ME series Modulator Drivers include a crystal-controlled RF oscillator, fast modulation circuit, and a broadband RF power amplifier in a housing with a power supply, RFI line filter, and line switch. 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 10 watts for some models. Configuration options include a front panel user-accessible connection between the oscillator and modulation circuit (N) 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 (H) to give the Model ME drivers capability to be used as a stand-alone RF power amplifier. Drivers with option E provide a CW +10 dBm crystal oscillator reference output.
