The Model 46.32 Voltage Controlled Oscillator is a companion module which interfaces to the Model 42.70 Seismic Amplifier for analog telemetry requirements in the Compact Remote Station Model 45.50. The Model 46.32 is designed to convert signals from the seismic amplifier to narrow-band telemetry channels. The outputs from multiple VCO's can be summed together (multiplexed) to permit transmission over a single pair of wires. The following standard center frequencies are supported, each with a bandwidth of ±125 Hz.: 340, 680, 1020, 1360, 1700, 2040, 2380, 2720, and 3060 Hz. Special channels and deviations are available on request. The Model 46.32 needs ±12 V, while the Model 46.32-1 needs only +12 V to operate.
