The PPS-2 is used to generate one pulse per second signals from a sine-wave input signal. The input can be a 1 MHz, 5 MHz or 10 MHz signal. The pulse-per-second (pps) output has a variable pulse width. The input frequency selection and pulse width selections are configured via jumper settings. The output pps can synchronize with an external event. The synchronization is good to +/- ½ of the input clock cycle.
The outputs are designed to drive low impedance loads and long 50 or 75-ohm cables. The channel-to-channel delay differences are less than 1 ns.
