FORMat subsystem
The commands in this subsystem are used to select the data format for
transferring instrument readings over the bus, or measured harmonic queries.
The BORDer command and DATA command only affect readings
transferred from the buffer. (i. e. SENSE:DATA? or CALC:DATA? are
always sent in ASCII.) The FORMat subsystem commands can also be used
with OUTP:LIST:DATA?, HARM:MAGN?, and SENS:DIST:FFT:BINS?
queries. These commands are summarized in Table 5-4.
:DATA command
[:DATA] <type>
:FORMat[:DATA] <type> Specify data format
Parameters <type> = ASCII ASCII format
SREAL IEEE754 single precision format
DREAL IEEE754 double precision format
Query [DATA]? Query data format
Description This command is used to select the data format for transferring readings over
the bus. For every reading conversion, the data string sent over the bus
contains the elements specified by the :ELEMents command. The specified
elements are sent in a particular order.
The ASCII data format is in a direct readable form for the operator. Most
BASIC languages easily convert ASCII mantissa and exponent to other
formats. However, some speed is compromised to accommodate the
conversion. Figure 5-1 shows the ASCII format that includes all the data
elements.
