Generating Signals with the PXI-5404 in SignalExpress

Primary Software: LabVIEW Signal Express>>Development System
Primary Software Version: 2.0
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: Signal Sources (AWG/FG/AO)>>Arbitrary Waveform and Function Generators>>PXI-5404

Problem:

The NI-FGEN Generation Steps in SignalExpress don't recognize the PXI-5404 hardware. How can I use this card in SignalExpress?

Solution:

The NI-FGEN step in SignalExpress 2.0 is based on the NI-FGEN Express VI. Unfortunately, this NI-FGEN Express VI does not support using the NI 5404. The example, 5404 User Defined Step for Signal Express, was created to accommodate this unsupported feature through the use of a User-Defined step that achieves this desired functionality.

Instructions for the 5404 User Defined Step Example for SignalExpress 2.0

  1. Insert a User-Defined Step in your SignalExpress 2.0 project.

  2. Browse for the 5404_User_Defined_Step.vi located in the 5404_User_Defined_Step.llb.



  3. Select the Configure VI tab on the Step Setup Dialog Box.

  4. Specify the appropriate device, configuration, and functionality for your measurement application.



  5. Click the Run button to begin simultaneously outputting a sine wave and clock pulse on your 5404. Notice that you can modify the characteristics of the outputs as the step is running.

  6. If you have an NI Scope card, wire the outputs of your 5404 to the inputs of your Scope card and add an NI-Scope Acquire Step in Signal Express to measure the generated signals. Otherwise, view this clock frequency on an oscilloscope or other instrument. Remember that the 5404 has an output impedance of 50 Ohms.
