SCPI parameters
Many commands are supplemented by a parameter or a list of parameters. The
parameters must be separated from the header by a whitespace (ASCII code 0 to 9, 11
to 32 decimal, e.g. blank). If several parameters are specified in a command, they are
separated by a comma ",".
Allowed parameters are:
●
Numeric values
●
Special numeric values
●
Boolean parameters
●
Text
●
Character strings
●
Block data
The required parameters and the allowed value range are specified in the command
description.
Numeric values
You can enter numeric values in the following form. Values exceeding the resolution of
the instrument are rounded up or down.
Example:
VOLT 10V
=
VOLT 10
VOLT 100mV
=
VOLT 0.1
Special numeric values
The text listed below are interpreted as special numeric values. In the case of a query,
the numeric value is provided.
●
MIN
/
MAX
●
MINimum
and
MAXimum
denote the minimum and maximum value.
Example:
VOLT:PROT? MAX
Returns the maximum numeric value.

●
On
(logically true), is represented by "On" or the numeric value "1"
●
Off
(logically false), is represented by "Off" or the numeric value "0"
The instrument returns the numerical value when queried.
