ABSTRACT:
A remote calibrated power source system comprises an instrument for generating power, the instrument being positioned at a first location, and a remote calibrated power source module for outputting calibrated power, the remote module being positioned at a second location that is removed from the first location. The remote module includes power sampling means for sampling the power generated by the instrument and generating a sampled voltage, the power sampling means having inherent frequency errors, a compensation circuit for generating a frequency-varying correction voltage, and summing amplifier means for receiving both the correction voltage and the sampled voltage and generating a compensated sampled voltage. The instrument includes oscillator means for generating the power, reference voltage means for generating a reference voltage, comparison means for receiving both the reference voltage and the compensated sampled voltage of the remote module and generating a modulating signal, and modulator means for receiving the modulating signal and modulating the power generated by the oscillator means, whereby the instrument and the remote module cooperatively generate the calibrated power.
