Command Description R&S SMC100A
1411.4060.32 6.12 E-1
FORMat Subsystem
The FORMat subsystem contains the commands which determine the format of the data that the
R&S Signal Generator returns to the controller. This affects all query commands which return a list of
numerical data or block data. Reference is made to this in the descriptions of the commands.
Command Parameters Default unit Remark
FORMat[:DATA] ASCii | PACKed
FORMat:BORDer NORMal | SWAPped
FORMat:SREGister ASCii | BINary | HEXadecimal | OCTal
FORMat[:DATA] ASCii | PACKed
The command determines the data format which the R&S Signal Generator uses to return data.
When data is transferred from the control computer to the instrument, the instrument detects the
data format automatically. In this case, the value set here is irrelevant.
Parameters: ASCii
'Numerical data is transferred as plain text separated by commas.
PACKed
'Numerical data is transferred as binary block data. The format within the
binary data depends on the command. The various binary data formats are
explained in the description of the parameter types.
*RST value Resolution Options SCPI
ASCii - Compliant
FORMat:BORDer NORMal | SWAPped
The command determines the sequence of bytes within a binary block. This only affects blocks
which use the IEEE754 format internally.
Parameters: NORMal
'the R&S Signal Generator expects (with setting commands) and sends (with
queries) the least significant byte of each IEEE754 floating-point number first,
and the most significant byte last.
SWAPped
'the R&S Signal Generator expects (with setting commands) and sends (with
queries) the most significant byte of each IEEE754 floating-point number first,
and the least significant byte last.
Example:
FORM:BORD SWAP
'the data is transferred with the most significant bit first.
*RST value Resolution Options SCPI
NORMal - Compliant
