Creating and Downloading Waveform Files
Downloading E443xB Signal Generator Files
• Agilent Waveform Download Assistant: http://www.agilent.com/find/downloadassistant
This software provides functions for the MATLAB environment to download waveform data.
Downloading E443xB Signal Generator Files
To download earlier E443xB model I and Q files, use the same SCPI commands as if downloading
files to an E443xB signal generator. The signal generator automatically converts the E443xB files to
the proper file format as described in “Waveform Structure” on page 193 and stores them in the
signal generator’s memory. This conversion process causes the signal generator to take more time to
download the earlier file format. To minimize the time to convert earlier E443xB files to the proper
file format, store E443xB file downloads to volatile memory, and then transfer them over to
non-volatile (NVWFM) memory.
NOTE You cannot extract waveform data downloaded as E443xB files.
E443xB Data Format
The following diagram describes the data format for the E443xB waveform files. This file structure
can be compared with the new style file format shown in “Waveform Structure” on page 193. If you
create new waveform files for the signal generator, use the format shown in “Waveform Data
Requirements” on page 185.
