Model 1201B/C delivers better than 100 ns accuracy and includes the most highly sought after features in a precision time clock as standard plus many enhancements.

Three terminal strip outputs are jumper selectable to unmodulated IRIG-B, modulated IRIG-B, 1 PPS, programmable pulse, or event input. The Model 1201B/C is capable of driving multiple loads in parallel.

Like other Arbiter clock models, various options are available to add features such as NTP/PTP (Network Time Protocol/Precision Time Protocol [IEEE 1588]) support, four additional configurable outputs, high drive IRIG-B outputs, Power System Time, Frequency, and Phase Monitor functions, one Form C (SPDT) fail-safe, LOCKED relay that is compatible with 129 Vdc digital fault recorder inputs; plus many more.

Model 1201B/C is available with two front panel configurations (see photos and Key Features tab). Each product includes the GNSS antenna and cable, a terminal power strip, and a rack mount kit, all backed by a Ten Year Limited Warranty to the original owner/purchaser.
