Frequently Asked Questions

Common questions about XHTF1003-H Rubidium Frequency Standard

What makes the XHTF1003-H compatible with existing LPRO installations?

The XHTF1003-H is designed to be compatible with the LPRO Rb atomic clock and uses a filter-array I/O connection port, allowing it to replace LPRO units while adding RS-232C serial communication for control and monitoring.

What phase noise does the XHTF1003-H achieve?

In its high-performance grade the 10 MHz phase noise is <-80 dBc/Hz at 1 Hz, <-95 dBc/Hz at 10 Hz, <-135 dBc/Hz at 100 Hz, <-145 dBc/Hz at 1 kHz, <-150 dBc/Hz at 10 kHz, and <-162 dBc/Hz at 100 kHz.

How is the XHTF1003-H powered and monitored?

It operates from a +24 V supply and provides a 10 MHz RF output, a lock-status line, an Rb light indication, and external electric-level adjustment, with RS-232C serial communication for comprehensive monitoring.
