14-2 FORMat and Misc SYSTem Commands Model 2700 Multimeter/Switch System User’s Manual
FORMat commands
The commands in this subsystem are used to select the format for transferring data,
Table 14-1, over the bus.
FORMat[:DATA] <type>[,<length>]
Parameters ASCii = ASCII format
SREal = Binary IEEE-754 single precision format
REAL, 32 = Binary IEEE-754 single precision format
DREal = Binary IEEE-754 double precision format
REAL, 64 = Binary IEEE-754 double precision format
NOTE <length> is not used for the ASCii, SREal, or DREal parameters.
The response to READ?, FETCh?, MEASure?, TRACe:DATA?, CALC1:DATA?, or
CALC2:DATA? over the GPIB can be returned in either the ASCii or binary format. All
other queries are returned in ASCii, regardless of the selected format. Over the RS-232
interface, only the ASCII format is allowed.
NOTE Regardless of which data format for output strings is selected, the instrument
will only respond to input commands using the ASCII format.
