Creating and Downloading Waveform Files

Commands for Downloading and Extracting Waveform Data

SCPI Command Line Structure

The signal generator 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

"<file_name>" the I/Q file name and file path within the signal generator

# indicates the start of the data block

A the number of decimal digits present in B

B a decimal number specifying the number of data bytes to follow in C

C the actual binary waveform data

The following example demonstrates this structure:

WFM1: the file path

my_file the I/Q file name as it will appear in the signal generator’s memory catalog

# indicates the start of the data block

3 B has three decimal digits

240 240 bytes of data to follow in C

12%S!4&07#8g*Y9@7... the ASCII representation of some of the binary data downloaded to the

signal generator, however not all ASCII values are printable

Commands and File Paths for Downloading and Extracting Waveform Data

NOTE Filenames should not exceed 23 characters.

You can download or extract waveform data using the commands and file paths in the following

tables:

• Table 7, “Downloading Unencrypted Files for No Extraction (Extraction allowed on the Agilent

MXG Only),” on page 25

• Table 8, “Downloading Encrypted Files for No Extraction (Extraction allowed on the Agilent MXG

Only),” on page 25

• Table 9, “Downloading Unencrypted Files for Extraction,” on page 25

• Table 11, “Downloading Encrypted Files for Extraction,” on page 27

• Table 12, “Extracting Encrypted Waveform Data,” on page 27
