  • This instrument is intended primarily for the calibration of an oscillator by beating it with the fundamental or harmonic of a second calibrated oscillator or the internal crystal oscillator.  Two internal crystals can be used; 2 and 5 MHz.  An external crystal can be used.  The useable range of the calibrator is from approximately 200 kHz to 300 MHz.
