Creating and Downloading Waveform Files

Downloading Waveform Data

For advanced programming languages, this section closely examines the code algorithm for downloading I/Q waveform data by breaking the programming examples into functional parts and explaining the code in generic terms. This is done to help you understand the code algorithm in downloading the interleaved I/Q data, so you can leverage the concept into your programming environment. While not discussed in this section, you may also save the data to a binary file and use one of the download utilities to download the waveform data (see “Using the Download Utilities” on page 227).

If you do not need the level of detail this section provides, you can find complete programming examples in “Programming Examples” on page 231. Prior to downloading the I/Q data, ensure that it conforms to the data requirements shown on page 185. To learn about I/Q data for the signal generator, see “Understanding Waveform Data” on page 185. For creating waveform data, see “Creating Waveform Data” on page 212.

NOTE To avoid overwriting the current waveform in volatile memory, before downloading files into volatile memory (WFM1), change the file name or turn off the ARB. For more information, on manually turning off the ARB, refer to the User’s Guide.

To turn off the ARB remotely, send: :SOURce:RADio:ARB:STATe OFF.

Using Simulation Software

This procedure uses a complex data array created in MATLAB and uses the Agilent Waveform Download Assistant to download the data. To obtain the Agilent Waveform Download Assistant, see “Using the Download Utilities” on page 227.

There are two steps in the process of downloading an I/Q waveform:

1.Open a connection session.

2.Download the I/Q data.

1. Open a connection session with the signal generator.

The following code establishes a LAN connection with the signal generator, sends the IEEE SCPI command *idn?, and if the connection fails, displays an error message.

Line

Code—Open a Connection Session

1io = agt_newconnection('tcpip','IP address');

%io = agt_newconnection('gpib',<primary address>,<secondary address>);

2[status,status_description,query_result] = agt_query(io,'*idn?');

3if status == -1

4display ‘fail to connect to the signal generator’;
