DNR-IRIG-650

DNR-IRIG-650
Timing generation and synchronization board for UEI’s RACKtangle® chassis
 
Timing generation and synchronization board for RACKtangle® chassis.
 
Characteristics:
  • IRIG-A, B, E and G output allows cube to provide timing signals
  • RIG-A, B, E and G input allows cube to synchronize with external IRIG-A, B, E and G sources
  • Modulated or DC level inputs and outputs
  • 1 PPS output
  • Event input captures timing to UTC
  • DNA-GPS input
  • 10 MHz, 1 ppm time base or slaved to external 10 MHz
  • DNA-CBL-650 cable (included with purchase) provides BNC connections for Clock/IRIG signals and 37-pin connections for other I/O
