FORMat Subsystem
FORMat commands specify the format for transferring measurement data.
FORMat[:DATA] ASCII|REAL
FORMat[:DATA]?
Specifies the format of the returned data. This is used by queries that can return a block of data. ASCII
returns data as ASCII bytes in numeric format as appropriate. The numbers are separated by
commas. REAL returns data in a definite length block as IEEE single precision floating point values. In
this case the 4 bytes of each value can be returned in either big-endian or little-endian byte order,
determined by the FORMat:BORDer setting.
Parameter Typical Return
ASCII|REAL, *RST ASCII ASCII or REAL
Sets the data format to ASCII: FORMatASCII
l The data format is used by a small sub set of queries that can return large quantities of data.
FORMat:BORDer NORMal|SWAPped
FORMat:BORDer?
Specifies how binary data is transferred. This only applies when the FORMat:DATA is set to REAL.
NORMal transfers data in normal order. The most significant byte is returned first, and the least
significant byte is returned last (big-endian). SWAPped transfers data in swapped-byte order. The
least significant byte is returned first, and the most significant byte is returned last (little-endian).
Parameter Typical Return
NORMal|SWAPped, *RST NORMal NORM or SWAP
Sets the data transfer to Swapped: FORM:BORD SWAP
l The byte order is used when fetching real data from SCPI measurements.
