Omicron CMIRIG-B Interface

OMICRON CMIRIG-B Interface

CMIRIG-B is an interface box enabling the connection of devices sending or receiving the IRIG-B protocol or PPS signals with CMC test sets. CMIRIG-B performs the level conversion between the CMC and the sources or receivers. The actual IRIG-B decoding and coding functionality is implemented in the CMC test set. CMGPS can optionally be used as source of a synchronizing trigger pulse or PPS signal.

Compatible test sets: CMC 356, CMC 353, CMC 256plus, CMC 850, CMC 256-6 with NET-1 Option

Applications

• Synchronization of the analog outputs of two or more CMC test sets with an external IRIG-B protocol or PPS signal. Example: End-to-end testing
• Testing of wide area protection with IRIG-B functionality using the IRIG-B time protocol generated by the CMC test set. Example: Testing of phasor measurement units (PMU). Supported standard (IRIG-B extension): IEEE C37.118 (Synchrophasor standard)
• Master/Slave Operation: A CMC test set (master) generates an IRIG-B protocol and synchronizes other CMC test sets (slaves) at the same location
