refers to window 1.
In order to refer to a window other than 1, you must include the optional
WINDow
parameter with the suffix for the required window.
DISP:WIND2:MAX ON

6.3.3 SCPI Parameters
Many commands are supplemented by a parameter or a list of parameters. The
parameters must be separated from the header by a "white space" (ASCII code 0 to 9,
11 to 32 decimal, e.g. blank).
The parameters required for each command and the allowed range of values are
specified in the command description.
Allowed parameters are:
● Numeric Values .....................................................................................................486
● Special Numeric Values ........................................................................................487
● Boolean Parameters ............................................................................................. 488
● Text Parameters ....................................................................................................488

6.3.3.1 Numeric Values
Numeric values can be entered in any form, i.e. with sign, decimal point and exponent.
Values exceeding the resolution of the instrument are rounded up or down. The man-
tissa may comprise up to 255 characters, the exponent must lie inside the value range
-32000 to 32000. The exponent is introduced by an "E" or "e". Entry of the exponent
alone is not allowed.
Example:
