Redundant Reference Generator REFGEN RED 10354 5 / 10 MHz, 1 PPS, IRIG, GPS receiver, NTP server TCP Command & Data Output Interface, and Serial Interface The References Generator supports a management and control interface (M&C) on its TCP/IP ports #2000 and #2001. The same function is also available via a serial RS232 interface. Regularly issued status reports as well as status reports on request are provided. For the data being available for such state reports see the list of monitored parameters below. UDP Interface The state reports can be made available also at UDP ports. This allows any external station controller for getting the REFGEN-RED state just by listening to this port. Monitored Parameters The Reference Generator monitors all essential states of its internal hardware as well as the states of the inputs signals, the states of the output signals, the state of the internal oscillator control loop, and the states of the time interval counters.

In addition to the well known IRIG codes, a IRIG B code with a 5 MHz carrier frequency is available. IRIG codes are output as modulated codes and as DC shift outputs. The IRIG generator supports 4 independent IRIG channels transporting IRIG codes. Each channel can be configured for an individual IRIG code. The generator provides 4 channels with configurable modulation property at external output interfaces and distributes these IRIG channels internally to the IRIG distributor modules. Each IRIG distributor is configured for distribution of one of these channels providing 4 equal IRIG outputs according to the selected IRIG channel.

Redundant Reference Generator REFGEN RED 10354 5 / 10 MHz, 1 PPS, IRIG, GPS receiver, NTP server Both redundant IRIG generators are configured equal. The REFGEN-RED provides two types of IRIG outputs, non-protected outputs from the IRIG generator and protected outputs from the IRIG distributors.

The generator modules have non-protected outputs being printed in normal face here. The slot 7 of the REFGEN-RED standard configuration is still unused. It can be equipped with optional distribution modules. Oscillator options are available on slot#1. The Ultra Low Phase Noise Oscillator output is 5 MHz instead of 10 MHz as for the standard REFGEN-RED, the Rubidium Oscillator output is 10 MHz.
