compatibility with the SCPI standard, the device must be able to recognize the full length
of the command. Some of the commands become considerably shorter when the optional
keywords are omitted.
Example:
[SENSe:]POWer:TSLot:COUNt 6
This command sets for sensor 1 the number of timeslots in the Timeslot mode to 6. The
following command has the same effect.
POWer:TSLot:COUNt 6
An optional keyword cannot be omitted if its effect is specified in more detail by a numeric
suffix.
Example:
SENSe2:POWer:TSLot:COUNt 6
This command sets for sensor 2 the number of timeslots in the Timeslot mode to 6.
Keyword SENSe cannot be omitted.
Long and short form
The keywords have a long and a short form. The keyword may be entered in short or in
long form; other abbreviations are not allowed. The short form uses the first four char-
acters of the long form. If the fourth character is a vowel and the long form consists of
more than four characters, only the first three characters are used for the short form. The
short form is shown by upper-case characters, and the long form is the entire keyword.
Upper case and lower case notation only serves to distinguish the two forms in the man-
ual, the instrument itself is case-insensitive.
Example:
STATus:QUEStionable:ENABle 1
and
STAT:QUES:ENAB 1
Parameters
The parameter must be separated from the header by a white space. If a command con-
tains several parameters, they have to be separated by a comma (,). Some of the com-
mands allow the specification of the parameters
MINimum
,
MAXimum
and
DEFault
. For
a description of the parameter types

chapter 5.7.5, "Parameters" , on page 177.
Example:
TIMing:EXCLude:STARt? MINimum
Response: 0
This query asks for the minimum setting value.
Numeric suffix
If a device has several identical functions or features, e.g. inputs, the desired function
can be selected by a suffix to the command. Commands without a suffix are interpreted
as having a suffix of 1.
