ABSTRACT:
A spectrum analyzer corrects for internal frequency errors in a reference oscillator using a timing control signal. The reference oscillator provides a reference signal at a reference frequency. An error detection circuit determines an error in the reference frequency using the timing control signal and produces an error correction signal for use by a frequency conversion device in adjusting an output frequency thereof to compensate for the frequency error in the reference frequency.
