DRFA10Y Voltage Controlled Oscillators
Description
DRFA (Voltage Controlled Oscillators) are analog devices and are suitable for general purpose applications (raster scan, or random access…). The DRFA provides not only amplitude modulation but frequency modulation, both through external analog signals. An external power amplifier will be required to generate the RF power levels required by the AO device.
For laboratory version, the frequency source + the convenient amplifiers are integrated in a box supplied with 110-230 VAC. A switch on the front panel allows the user to select both operating modes: CW mode: internal CW modulation of RF power with front panel cursor EXT mode: external amplitude modulation controlled through external modulation input
