:FORMat:BORDer <char1>
:FORMat:BORDer?
Description
Sets the binary numeric I/O data byte order as either Most Significant Byte (MSB) or Least Significant Byte (LSB) byte order of binary numeric I/O data where:
• NORMal = The MSB is first
• SWAPped = The LSB is first.
The query outputs the Most Significant Byte (MSB)/Least Significant Byte (LSB) byte order of binary numeric I/O data.
Cmd Parameters
<char1> NORMal | SWAPped
Query Parameters
<char1> NORM | SWAP
Range
NA
Default Value
SWAP
Syntax Example
:FORM:BORD NORM
:FORM:BORD?
 
:FORMat:DATA <char1>
:FORMat:DATA?
Description
The command sets the format for numeric I/O data representation where:
• ASCii = An ASCII number of 20 or 21 characters long with floating point notation. For example, 12345E-4.
• REAL = 8 Bytes of binary floating point number representation limited to 64 bits which is the value of the MPND (Maximum Positive/Negative Double Precision Number or +/- 1.792 631 348 6E38)
• REAL32 = 4 Bytes of floating point number representation which is the value of the MPNF (Maximum Positive/Negative Floating Point Number or +/- 3.402 819E38)
The query outputs the format of numeric I/O data representation.
Cmd Parameters
<char1> ASCii | REAL | REAL32
Query Parameters
<char1> ASC | REAL | REAL32
Range
NA
Default Value
ASC
