:FORMat Subsystem
This subsystem sets the data format for transferring numeric information. This
data format is used for response data by those commands that are specifically
designated to be affected by the :FORMat subsystem.
:FORMat[:DATA] ASCii | REAL
Sets or queries the data format type. Valid types are ASCii and REAL.
When ASCii type is selected, numeric response data is transferred as ASCII bytes
in <NR3> format. The numbers are separated by commas as specified in IEEE
488.2. To indicate that no response data exists, Not a Number 9.91E37 is
returned.
When REAL type is selected, response data is transferred in a
<definite length block> as a 64-bit IEEE 754 floating point number. To indicate
that no response data exists, Not a Number 9.91E37 is returned in the <definite
length block>.
A sequence of ASCII-encoded bytes: ASC or REAL
• *RST: ASCii
• This command affects the response format of the following commands:
:CALCulate:DATA?
:CALCulate3:DATA?
:FETCh?
:MEASure query
:READ?
[:SENSe]:DATA?
:TRACe[:DATA] query
