DAQ-STC: Generating a Delayed Pulse (Intermediate VIs)

Filename: delayed_pulse-int__daq-stc_.zip
Requirements: View

This VI generates a delayed pulse on the OUT pin of the chosen counter. This VI works with devices that have a DAQ-STC counter timer chip. Examples of these devices are the PXI-6070, PCI-MIO-16E-1, and AT-MIO-16E-2.

INSTRUCTIONS:
1. Enter the device number of your board.
2. Enter the counter number.
4. Enter the pulse delay in seconds.
5. Enter the pulse width in seconds.
6. Choose the pulse polarity.
7. Make the appropriate I/O connections as explained below.
8. Run the VI.

KEY PARAMETERS:
This VI uses the Intermediate level VIs: Delayed Pulse Generator Config.vi, Counter Start.vi, and Counter Stop.vi to produce a single delayed pulse on the chosen counter. The Delayed Pulse Generator Config.vi configures the counter to output a single pulse. The Counter Start.vi initiates the delayed pulse. The Wait+ (ms).vi is used as a delay before the counter is reset. Finally, the Counter Stop.vi resets the counter.

The "actual width" and "actual delay" outputs may differ from your desired inputs because they are integer multiples of an internal timebase. It may be that your exact desired delay or width cannot be obtained.

I/O CONNECTIONS:
Connect to the OUT pin of your chosen counter for the delayed pulse.
If you choose a timebase source other than internal, wire your external clock to the SOURCE input of the chosen counter.
If you choose a gate mode other than ungated, wire your external gate signal to the GATE pin of your chosen counter.
To find the actual pin numbers, refer to the hardware user manual.

DAQ VIs USED:
Delayed Pulse Generator Config.vi, Counter Start.vi, Counter Stop.vi.
