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 5-7, “Downloading Unencrypted Files for No Extraction (Extraction allowed on the Keysight MXG
Only),” on page 237
• Table 5-8, “Downloading Encrypted Files for No Extraction (Extraction allowed on the Keysight MXG
Only),” on page 237
• Table 5-9, “Downloading Unencrypted Files for Extraction,” on page 237
• Table 5-11, “Downloading Encrypted Files for Extraction,” on page 239
• Table 5-12, “Extracting Encrypted Waveform Data,” on page 239
