External Strobe Signal
External Strobe is an output-only signal on the EXT STROBE pin that generates either a single pulse or a sequence of eight pulses in the hardware-strobe mode. An external device can use this signal to latch signals or to trigger events. In the single-pulse mode, software controls the level of External Strobe. A 10 ms and a 1.2 µs clock are available for generating a sequence of eight pulses in the hardware-strobe mode. The following figure shows the timing for the hardware-strobe mode External Strobe signal.
 | Note External Strobe is used for signal conditioning with SCXI and is not available for use with NI-DAQmx. |
