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.

Channel Bandwidth
Channel Bandwidth is the bandwidth over which power is measured. This is usually the bandwidth in which almost all of the power of a signal is contained.

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Overshoot
Overshoot is the distortion that follows a major transition; the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude.

Rise Time
Rise time refers to the time required for a signal to change from a specified low value to a specified high value, usually 10 and 90 percent of pulse-top amplitude (vertical display is linear power).
