Counter 1 Internal Output Signal

The Counter 1 Internal Output (Ctr0InternalOutput) signal is the output of Counter 1. This signal reflects the terminal count (TC) of Counter 1. The counter generates a terminal count when its count value rolls over. The two software-selectable output options are pulse on TC and toggle output polarity on TC. The output polarity is software-selectable for both options. The following figure shows the behavior of the Ctr1InternalOutput signal.

You can use Ctr1InternalOutput in the following applications:

  • In pulse generation mode, the counter drives Ctr1InternalOutput with the generated pulses. To enable this behavior, software configures the counter to toggle Ctr1InternalOutput on TC.
  • Ctr1InternalOutput can control the timing of analog output acquisitions by driving ao/SampleClock (NI 6110/6111 only).
  • Counter 0 and 1 can be daisy-chained together by routing Ctr1InternalOutput to Ctr0Gate.
  • Ctr1InternalOutput drives the CTR 1 OUT pin to trigger or control external devices.
  • Ctr1InternalOutput can drive other internal signals.
