Main components of this application:

-          Configure record settings to maximize dynamic range:  Set RFSA Record Settings.vi

-          Save record parameters on a XML header file:  RF Header File.vi

-          Simple NI PXI-5661 Record:  niRFSA Simple Record.vi

-          Simple NI PXIe-5672 Playback:  PXIe Simple Playback.vi

-          Load, save and manage the header file:  RF Header File.vi

 

The file includes a User Interface (UI) where all the components are called in the correct order. To visualize the components interaction, Figure 1 displays the hierarchy of the VI.

 

Figure 1. Hierarchy of User Interface (UI) that calls each component

This is a very simple UI to help understand how the pieces work together.

 

Instructions:

1.       Run the VI

2.       Select the destination file name where the data will be written to.

3.       Select the RFSA resource name.

4.       Press the Configure & Record Data button. A UI will pop up that will let you configure span, center frequency and input power level that you want to record your signal with.

5.       Move the Range slide control down until your saturation is in the green zone (Best Saturation Level). Set the Span you want to record and the center frequency. Furthermore, you can specify the time you would like to record for in hh:mm:ss format.

6.       Press Accept Configuration

7.       A window will pop up displaying the status of the recording:

 

 

8.       Press stop or wait for the recording to finish.

9.       You will go back to the initial UI where you can select Analyze and see the following display:

10.   Press stop when you finish (you can always perform offline analysis even if you do not have hardware).

11.   Select the correct RFSG resource name and press Playback. A window will display the status of the generation.
