IQD Evaluation Board

Designed by IQD Frequency Products utilising over 50 years of oscillator testing measurement experience, the oscillator evaluation board is intended to facilitate basic testing of standard oscillators, voltage controlled oscillators and temperature compensated oscillators. The board can provide a regulated power supply to the oscillator between 1.8V and 5.0V. A buffered output with the correct loading is provided for CMOS output devices or clipped sine wave output devices. There is also an unbuffered output for further testing. There is capability to test the enable disable function, and also to control the voltage input of a voltage controlled crystal oscillator product.
