Commands for Downloading and Extracting Waveform Data
Commands for Downloading and Extracting Waveform Data
You can download I/Q data, the associated file header, and marker file information (collectively called
waveform data) into volatile or non-volatile memory. For information on waveform structure, see
“Waveform Structure” on page 193.
The signal generator provides the option of downloading waveform data either for extraction or not
for extraction. When you extract waveform data, the signal generator may require it to be read out in
encrypted form. The SCPI download commands determine whether the waveform data is extractable.
If you use SCPI commands to download waveform data to be extracted later, you must use the
MEM:DATA:UNPRotected command. If you use FTP commands, no special command syntax is
necessary.
NOTE On the N5182A, :MEM:DATA enables file extraction. On the N5182A the
:MEM:DATA:UNPRotected command is not required to enable file extraction. For more
information, refer to the SCPI Command Reference.
You can download or extract waveform data created in any of the following ways:
• with signal simulation software, such as MATLAB or Agilent Advanced Design System (ADS)
• with advanced programming languages, such as C++, VB or VEE
• with Agilent Signal Studio software
•with the signal generator
Waveform Data Encryption
You can download encrypted waveform data extracted from one signal generator into another signal
generator with the same option or software license for the modulation format. You can also extract
encrypted waveform data created with software such as MATLAB or ADS, providing the data was
downloaded to the signal generator using the proper command.
When you generate a waveform from the signal generator’s internal ARB modulation format
(ESG/PSG only), the resulting waveform data is automatically stored in volatile memory and is
available for extraction as an encrypted file.
When you download an exported waveform using a Agilent Signal Studio software product, you can
use the FTP process and the securewave directory or SCPI commands, to extract the encrypted file
to the non-volatile memory on the signal generator. Refer to “File Transfer Methods” on page 205.
