If you encounter problems with GPIB communications, the terminator string can
sometimes be the cause.
Command Separators
You can put more than one command on the same line (same command string) if
you separate them with a semicolon.
Note:
The semicolon can be preceded by one or more spaces. Examples:
TEC:DIS 1; tec:set:t?;
TEC:MODE:t ; TEC:T 25 ; TEC:Const 1, 2, 3.5 ; TEC:OUT 1g1
Parameters
Some commands require a parameter. The parameter must be separated from
the command by at least one space.
The syntax symbol
<nrf value>
refers to the flexible numeric representation
defined by the GPIB standard. It means that you can represent numbers in
integer or floating point form, or in engineering/scientific notation. The IEEE-488.2
standard uses the names NR1, NR2, and NR3 respectively to denote "integer",
"floating point", and "scientific notation". For example the number
twenty
may be
represented by any of the following ASCII strings:
There are no default values for omitted parameters. If a command is expecting a
parameter and none is entered, an error is generated.
For further clarity in programming, the (Boolean) values of one (1) and zero (0)
may be used or their names as indicated in the following table.
