Microsemi’s Time & Frequency systems offer picosecond measurement, hot swap power supplies, hitless switching, dual cooling fans, and redundant capabilities that make these products ideal for high reliability applications. Built on a modular platform, the highly accurate, precise generation and distribution of time and frequency output signals can help meet the highest precision and most complex timing and frequency requirements.
The TSC MM delivers cost-effective measurement of the phase difference between multiple continuous wave RF signals.
The TSC MMS is a multiple mixer measurement system designed to measure the phase difference between an RF signal from the clock under test and a reference RF signal shared by the measurement channels on a four-channel measurement module. The TSC MMS samples all inputs once every second and computes the phase difference relative to the 32 MHz internal oscillator. The system can also be configured to measure as many as three different frequencies simultaneously, with a frequency range of one to 20 MHz.
Designed to expand from a base configuration of four signal inputs to a full 28 in a single chassis, the TSC MMS samples all inputs once every second and computes the phase difference relative to the 32 MHz internal oscillator.
The TSC MMS can be configured to measure as many as three different frequencies simultaneously, with a frequency range of one to 20 MHz.
With a base system designed for mounting in a 19-inch rack, expanding capacity is easy. Customers can increase the number of additional inputs simply by adding more standard modules, with four inputs available per module.
Powerful relational database from Microsemi enables storage and rapid data retrieval of as many as three years of one-second data in an ODBC/SQL interface.
The Precise Time-Scale System (PTSS) is a fully integrated, world class timing system capable of providing timing accuracies comparable to the best national laboratories. It can combine up to six high performance cesium frequency standards or Active Hydrogen Masers (AHMs) in a time scale that drives the local Real-Time Clock (RTC) signal. A high performance timing quality GNSS receiver provides the information used to steer the system output to UTC and generate GPS Common-View (CV) data. This allows the frequency standards to be reported to the International Bureau of Weights and Measures (BIPM) for inclusion in the international time scale.
The PTSS is a fully integrated solution that provides industry leading frequency stability, phase-noise performance, and time scale availability in a unit as small as one instrument rack.
Microsemi's single rack Precise Time-Scale System provides a real-time local UTC time scale. It can also apply the most accurate GNSS and Two- Way Satellite Time and Frequency Transfer (TWSTFT) techniques for measuring offsets between geographically dispersed clocks.
As the international standard time scale, Universal Coordinated Time (UTC) is the composite of clocks throughout the world. The time of each clock is reported to BIPM using either GNSS CV or TWSTFT. National laboratories also compute a local time scale steered to agree with UTC designated as UTC(lab), where lab is the BIPM assigned name of the laboratory producing the time scale. Local UTC Time-Scale systems have state-of-the-art frequency stability, phase noise performance, and system availability.
The Microsemi Precise Time-Scale System meets those requirements using Microsemi manufactured precise timing products. The PTSS offers faster deployment, ease of use, lower ownership cost, higher product quality, reliable operation, and a single point of responsibility for all system support.
