SYMMETRICOM 8040C Rubidium Frequency Standard

The Symmetricom 8040C Rubidium Frequency Standard solves this problem by providing a stable and accurate frequency reference with multiple output signal formats in an easy to install 1U rack mountable chassis. Unlike other units, the 8040C offers configurable RF outputs, external GPS disciplining and a RS-232 interface for command and control. It has six outputs, each of which can be user configured to provide a 1 MHz, 5 MHz or 10 MHz sine, square wave, or 1PPS output. The standard configuration of the 8040C has three 10 MHz, one 5 MHz, one 1 MHz and 1PPS output.

Standard Calibration $720.00 *
*This is a Web introductory price for one calibration of the SYMMETRICOM 8040C. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Clipping
Clipping is the limiting of a signal so that it never exceeds some threshold.

Line Regulation
Line regulation is the capability to maintain a constant output voltage level on the output channel of a power supply despite changes to the input voltage level.

Peak Envelope Power
Peak envelope power is the maximum value of the envelope power. Envelope power is measured by making the averaging time much less than 1/fm where fm is the maximum frequency component of the modulation waveform. The averaging time is therefore limited on both ends: (1) it must be small compared to the period of the highest modulation frequency, and (2) it must be large enough to be many RF cycles long.

RMS
RMS or root mean square is a statistical measure of the magnitude of a varying quantity
