Configuring a 1PPS Input

To configure a 1PPS Input:

  1. Navigate to INTERFACES > REFERENCES: PPS Input 0 (or: INTERFACES > OPTION CARDS: PPS Input 0).

  3. Apply your settings for:
    • Edge: [Rising, Falling] The on-time point of the 1PPS input can be configured to be either the rising or falling edge of the 1PPS signal (by default, the rising edge is the on-time point).
    • Offset: [-500000000 to 500000000 ns = ±0.5 s] Allows to offset the system's 1PPS on-time point, e.g. to compensate for cable delays and other latencies
