Key Features
• Multiple RF outputs
•CsIII technology
•AC & DC inputs
•Internal battery back-up
•CE compliant
Key Benefits
• Configurable 3U rack mount chassis
allows for flexibility
• High stability, low noise RF and
1PPS reference makes it perfect for
high precision timing and frequency
applications
• Custom output signals available
The Microsemi® Cs4000 is a cesium
frequency standard platform that provides
exceptional performance in a configurable
3U rack mount chassis. The Cs4000 is
designed for high precision timing and
frequency applications requiring high
stability, low noise RF and 1PPS reference
signals. Microsemi’s advanced Cesium III
digital technology is the engine that drives
this exceptional performance. The Cs4000 is designed to provide
standard and custom output signal
formats simultaneously. Standard outputs
include, 100 kHz, 1, 5, 10 MHz and 1 PPS.
Custom output formats are supported via
a configurable custom output area capable
of supporting most custom signaling
requirements.
The Cs4000 meets the challenges of
laboratory standards, satcom terminals,
mobile communications systems and a
wide variety of test and measurement
applications.
• Standard 1 year electronics and 8-year
tube warranty
