Overview of Remote Control
Data Transfer
BINARY Format
When the :FORM:DATA REAL,64 command is executed, the E4980A/AL
transfers data in the BINARY format. This BINARY format is the 64-bit floating
point binary format specified in IEEE Standard 754-1985. The BINARY data
output format on the MEAS DISPALY, BIN No, or BIN COUNT page is shown
below.
Figure 8-23 BINARY Format 1
The BINARY data output format consists of the first four bytes (described
below), <DATA A>, <DATA B>, <STATUS>, <BIN No.>, 0 (ASCII), and the
terminator (NL).
# (1 byte): A code for the BINARY data output format
(ASCII character)
2 (1 byte): The number of the bytes for the “No. of the
bytes to transfer” (ASCII character)
No. of bytes to transfer (2 bytes): The number of data bytes of <DATA A>,
<DATA B>, <BIN No.> and 0
Data formats of the <DATA A>, <DATA B>, <STATUS>, and <BIN No.> are
common (8 bytes, IEEE754 floating point format) as follows. The meaning of
each data item is the same as that in the ASCII format.
