.3.5 Separators
(2) Query program headers
These headers are used to query the operation results, measurement results,
or the setting state of the unit.
As the example below, the commands are recognized as the query by the
question mark "?"which is put next to the program header.
Example :FUNCtion?
:RESIstance:RANGe?
The 3227 accepts LF, EOI, and LF with EOI, as the message terminators.
The "TRANsmit:TERMinator"command is also able to select followings as the
response message terminator.
(1) EOI + LF
(2) CR, EOI + LF
When the power supply is turning on, (1) is selected.
(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 ;
*
ESE 255 ;
:HEADer ON"
(2) Header separator
In a message which has a header and data, a space is used as the header
separator to separate the header from the data.
":HEADer
ON"
(3) Data separator
If a message has several data items, commas are required as a data separator
for separating these data items from one another.
":CSET:PARAmeter 10100 ,
9900"
