Filename: 200109.zip
Requirements: View

This VI generates one of two continuous pulse trains on the default OUT pin of the chosen counter. The level of the gate determines which pulse train will be outputted. This VI works with NI-TIO based devices (e.g.: 6602).

INSTRUCTIONS:
1. Enter the device and counter you want use.
2. Make your Pulse Specifications and Source selections, as desired.
3. Optional controls are located on the left side of the front panel. You will have to use your scroll bar to reach these.
4. Connect your signals as described below in I/O CONNECTIONS.
5. Run the VI.

KEY PARAMETERS:
Counter Group Config.vi: task type = frequency shift keying
Counter Source (NI-TIO).vi: Source Specification
Counter Gate (NI-TIO).vi: Gate Specification
Counter Set Attribute.vi: count1, count2, count3, count4
Counter Control.vi: Program, Reset

I/O CONNECTIONS:
Connect the frequency selection signal to the gate input of the selected counter.
If you selected the Source Selection to be "PFI line", connect your event count base signal to the PFI line indicated by "Source PFI line number used". (If you selected "Internal Timebase", no source connection is necessary.)
NOTE: For actual I/O pin numbers, please refer to your hardware user manual.
