8.3.6 Separators
The 3332 recognizes,
(1) linefeed character (LF; GP-IB and RS-232C),
(2) EOI signal (GP-IB only),
(3) LF with EOI (GP-IB only),
as message terminators.
To terminate a response message, the 3332 always provides the appropriate
EOI signal, and also sends a terminating character sequence. By the use of
the "TRANsmit:TERMinator" command either of the following can be
selected as response message terminator sequence:
The initial setting is in the column above.
A detailed explanation of the "TRANsmit:TERMinator" command is given in
Section 8.4.2, "Commands Specific to the 3332."
(1) Message unit separator
A semicolon ";" is used as a message unit separator when it is desired to set
out several messages on a single line.
"*RST ; :SCALe:CT_4 ; :AVERaging_64"
(2) Header separator
In a message which has a header and data, a space (represented by "_" in the
examples) is used as the header separator to separate the header from the
data.
":VOLTage:AUTO _ ON"
(actually, "_" is not displayed.)
(3) Data separator
If a message has several data items, commas are required as data separators
for separating these data items from one another.
":MEASure?_V , A,W,VA"
