These 5 commands set the data format for array transfers in and out of
the instrument:
l-l 16 HP-IB Programmi ng and Command Reference Guide
Specifies a fixed load, as opposed to a
sliding load or offset load, when defining a
standard during a cal kit modification.
The analyzer's internal binary format,
6 bytes-per-data point. The array is
preceded by a four-byte header. The first
two bytes represent the string " #H 'I,
the standard block header. The second
two bytes are an integer representing the
number of bytes in the block to follow.
transfers, not to be modified by the
computer nor interpreted by the user, are
required.
IEEE 32-bit floating-point format, 8
bytes-per-data point. The data is preceded
by the same header as in FORMl. Each
number consists of a l-bit sign, an g-bit
biased exponent, and a 23-bit mantissa.
computer supports single-precision
floating-point numbers.
IEEE 64-bit floating-point format, 16
bytes-per-data point. The data is preceded
by the same header as in FORMl. Each
number consists of a l-bit sign, an
1 l-bit biased exponent, and a 52-bit
mantissa. This format may be used with
double-precision floating-point numbers.
No additional precision is available in
the analyzer data, but FORM3 may be a
convenient form for transferring data to
your computer.
ASCII floating-point format. The data
is transmitted as ASCII numbers, as
described previously in "Output Syntax".
There is no header. The analyzer always
uses FORM4 to transfer data that is not
related to array transfers (i.e. marker
responses and instrument settings).
