FORMat Subsystem
FORMat Subsystem
The FORMat subsystem sets a data format for transferring numeric
and array information.
Byte Order
:FORMat:BORDer NORMal|SWAPped
:FORMat:BORDer?
Selects the binary data byte order for numeric data output. It controls
whether binary data is transferred in normal or swapped mode. In
normal mode the most significant byte is sent first. In swapped mode
the least significant byte is first.
Factory Preset
and *RST: Normal
Numeric Data format
:FORMat[:DATA] ASCii|REAL,32|REAL,64
:FORMat[:DATA]?
This command changes the format of the data output. It specifies the
format used for trace data during data transfer across any remote port.
REAL and ASCII formats will format trace data in the current
amplitude units. The format of state data cannot be changed. It is
always in a machine readable format only.
NOTE This command specifies the formats used for trace data during data
transfer across any remote port.
For corrected trace data (:TRACe[:DATA] with parameter
<trace_name>), REAL and ASCii formats will provide trace data in the
current amplitude units. INTeger format will provide trace data in
mdBm. The fastest mode is INTeger,32.
For uncorrected trace data (:TRACe[:DATA] with parameter
RAWTRACE), UINTeger and INTeger formats apply to RAWTRACE
queries, and return uncorrected ADC values. The fastest mode is
UINTeger,16.
