Read and Write Measurement Data
Data Transfer Format
IEEE 64-Bit Floating Point Format
In this format, a numeric consists of eight bytes. Therefore, assuming that one
measurement point consists of two pieces of a numeric, when 201 measurement points are
transferred, the total data length is 3216 bytes. The numeric is transferred in the format
shown in
Figure 6-4.
Figure 6-4 IEEE 64-Bit Floating Point Data Transfer Format
Specify Byte Order (Binary Transfer)
When one of the binary formats is selected as the data transfer format, the following GPIB
command can be used to specify the order in which each byte is transferred.
• FORM:BORD on page 373
For example, when data written in the IEEE 32-bit floating point format is read on a
computer running MS-DOS, by reversing the order in which bytes are read with the above
GPIB command, reformatting the data on the computer is not necessary.
