Downloading and Extracting Waveform Data

You can download I/Q data, marker files, or encrypted files into the PXB file system. For information on waveform structure, see Understanding Encrypted Waveform Structure.

You can download or extract waveform data created in any of the following ways:

• with signal simulation software, such as MATLAB or using advanced programming languages, such as C++, VB or VEE. (Refer to sample programs using Advanced Programming Languages for code algorithms using C++.)

• with Agilent Signal Studio software

Transferring Signal Studio Waveforms

When you download a waveform using an Agilent Signal Studio software product, you can use Windows file sharing, or SCPI commands to transfer the file to the PXB using one of the following protocols:

• SCPI over the GPIB or USB

• SCPI with sockets LAN (using port 5025)

• All standard Windows networking methods

Downloading Waveform Data Using SCPI Commands

You can download waveform data using the following SCPI commands:

:MMEMory:DATA "<file_name>",<data_block>

The PXB expects to see waveform data as block data (binary files). The IEEE standard 488.2-1992 section 7.7.6 defines block data. The following example shows how to structure a SCPI command for downloading waveform data (#ABC represents the block data):

:MMEM:DATA "<file_name>",#ABC

There are 3 ways to specify a "<file_name>":

1. Specify the file name "<myFile>” that will store the file in D:\User_My_Documents. 

2. Specify the file name with the full path "<D:\my_folder\myFile>” that will store the file in D:\my_folder\myFile .

3. Use the non-volatile file name: "NVWFM[1,2,3,...9]:my waveform.bin)". The file will be stored in the respective directory: D:\Waveforms\Channel[1,2,3,...9].

The following example demonstrates this structure:
