Precision Reference Devices

Apex Microtechnology Precision Reference Devices provide ultrastable sine wave outputs and a temperature coefficient over the full military temperature range. Accuracy improvement of the Apex Microtechnology Precision Reference devices is possible through a unique proprietary multipoint laser compensation technique. Significant improvements have been made in other performance parameters, including warm-up drift, line regulation, and long-term stability.
