GENERAL
The Model RFA1170-4 is a class AB amplifier designed to drive the LS700- series of Isomet high
power Germanium acousto-optic deflectors with up to 300Watts across a 40MHz bandwidth. When
fitted with the iMS4-L synthesizer and controller cards, the RFA1170-4 power amplifier exhibits
programmable phase shift and amplitude compensation capability across the four RF output
channels.
This model is optimized for very fast rise and fall times and may be operated CW.
(Always refer to the AO device data sheet).
The RFA1170-4 + iMS4-L combo includes a number of features to aid monitoring and control:
Temperature monitoring and thermal Interlock for the Amplifier and associated AO deflector
“-Enable” control signal to enable RF amplifier (Closed contact = Active)
External
“Trigger” input, 3v3 LV-TTL compatible
External
“Clock” input, 3v3 LV-TTL compatible
Additional features are available under software control.
Please refer to the Isomet Software Development Kit available on-line.
