:FORMat Subsystem

This subsystem contains commands that determine the formatting of numeric data when it is
transferred.
The format setting affects data in specific commands only. If a command is affected, it is
noted in the command description.
:FORMat[:READings][:DATA] ASCii|INTeger,32|REAL,32
:FORMat[:READings][:DATA]?
Description: This command specifies the format in which data is returned in certain
Parameter: ASCii|INTeger,32|REAL,32
Parameter Type: <char>
Default Value: ASCii
Related Command: :TRACe[:DATA]

Title: Numeric Data Format
commands.
ASCii format returns the data in comma-separated ASCII format. The
units are the current instrument units. This format requires many more
bytes so it is the slowest format. INTeger 32 values are signed 32-bit
integers in little-endian byte order. This format returns the data in
4-byte blocks.
Both INTeger,32 and REAL,32 formats return a definite block length.
Each transfer begins with an ASCII header such as #42204. The first
digit represents the number of following digits in the header (in this
example, 4). The remainder of the header indicates the number of bytes
that follow the header (in this example, 2204). You then divide the
number of following bytes by the number of bytes in the data format
you've chosen (4 for both INTeger,32 and REAL,32) to get the number of
data points (in this example, 551).
