1220A/26A Auto Switches
The ptf 1220A (1U) and 1226A (2U) Auto Switch is purpose designed for time and frequency applications where reliability criteria call for redundant RF and Pulse sources. Based on the latest advances in semiconductor technology, the unit accepts two input pairs consisting of an RF (sine/square) signal and a pulse (typically 1 PPS). Both primary and backup input pairs are monitored for signal health, and if either the primary RF or pulse signals are determined faulty, the unit automatically switches to the backup channel within < 3msec (typical). In addition to providing for local control from the instrument front panel, the comprehensive communications package provides status reporting and instrument control on both RS232 and Ethernet interfaces with a variety of available protocols. Range setting on the pulse and frequency inputs allows fast detection of RF signals from 20MHz and pulse ranges from 0.1second to 2 seconds, Front panel indicators include RF and fault monitoring on each of the input channels, together with active channel indication and operating mode (auto/manual). The 1226A (2&U) utilizes quad-bloc cards for additonal RF and Pulse outputs (up to 24 total).
