High-Speed Timing
Built from high-speed counters, the timing circuitry on the NI 1427 can
generate precise real-time control signals for your camera. Map the output
of this circuitry to a trigger line to provide accurate pulses and pulse trains.
Use these control signals to control exposure time and frame rate.
Note
For your convenience, the external control for cameras that support the NI 1427 has
been preprogrammed into the camera file. You can use MAX to specify the frequency and
duration of these signals in easy-to-use units.
The NI 1427 also allows you to route the external trigger inputs 0–3 onto
the camera control lines 1–4. Use MAX to select the source for the camera
control lines. You have the option to choose either the default control signal
that is specified in the camera file or the external trigger input as the source
for the camera control lines.
