Frequently Asked Questions
Common questions about XHTF1003-C1 Rubidium Frequency Standard
What environments is the XHTF1003-C1 designed for?
It uses an anti-vibration, shock-prevention design and is suited to airborne and military-truck environments, communicating over an RS-422 serial port and powered from a +28.5 V (±3 V) supply.
What phase noise performance does the XHTF1003-C1 offer?
In its high-performance grade the 10 MHz single-sideband phase noise is <-80 dBc/Hz at 1 Hz, <-105 dBc/Hz at 10 Hz, <-135 dBc/Hz at 100 Hz, <-140 dBc/Hz at 1 kHz, and <-148 dBc/Hz at 10 kHz.
Is the XHTF1003-C1 compatible with existing LPRO-based designs?
Yes. It is designed as a high-performance rubidium frequency standard compatible with the LPRO Rb atomic clock, providing an SMA RF output and a J14A-9 interface for a straightforward upgrade path.
