FTR-210R

A frequency and time reference has two requirements that pull against each other: long-term accuracy (tracking UTC) and short-term stability (low noise). A GNSS receiver alone is accurate over the long term but noisy over seconds; a rubidium clock alone is stable over seconds but drifts slowly. The FTR-210R locks the two together so that rubidium supplies the short-term stability and GNSS applies the long-term correction, and both requirements are met at once. That decides where it is used: calibration labs run it as a working standard with traceability upward; telecom and satellite ground stations synchronize equipment from it; aerospace and defense test ranges use it as the common timebase for the whole site. The output set is flexible: the standard 5 x 10 MHz, 1 x 5 MHz and 1 x 1 pps grows to as many as 11 outputs, and options add 2 x 100 MHz plus a programmable pulse output from 0.5 Hz to 100 MHz with IRIG-B DCLS, so one unit feeds equipment with different interface needs. Because traceable calibration is built in, an audit does not require separate proof of traceability. Evencat is the authorized distributor for Pendulum Instruments in Taiwan and quotes the FTR-210R with its output and software options.
