8.2.4 Optional Keywords
Some keywords are optional and are only part of the syntax because of SCPI compli-
ance. You can include them in the header or not.
Note that if an optional keyword has a numeric suffix and you need to use the suffix,
you have to include the optional keyword. Otherwise, the suffix of the missing keyword
is assumed to be the value 1.
Optional keywords are emphasized with square brackets.
Example:
Without a numeric suffix in the optional keyword:
[SENSe:]FREQuency:CENTer
is the same as
FREQuency:CENTer
With a numeric suffix in the optional keyword:
DISPlay[:WINDow<1...4>]:ZOOM:STATe
DISPlay:ZOOM:STATe ON
enables the zoom in window 1 (no suffix).
DISPlay:WINDow4:ZOOM:STATe ON
enables the zoom in window 4.
8.2.5 Alternative Keywords
A vertical stroke indicates alternatives for a specific keyword. You can use both key-
words to the same effect.
Example:
[SENSe:]BANDwidth|BWIDth[:RESolution]
In the short form without optional keywords,
BAND 1MHZ
would have the same effect
as
BWID 1MHZ
.
8.2.6 SCPI Parameters
Many commands feature one or more parameters.
If a command supports more than one parameter, these are separated by a comma.
Example:
LAYout:ADD:WINDow Spectrum,LEFT,MTABle
Parameters may have different forms of values.
