Upper and lower case notation of commands
Upper-case and lower-case notation only serves to distinguish the two forms in the
manual, the instrument itself does not distinguish upper-case and lower-case letters.
Parameter
The parameter must be separated from the header by a "white space". If several
parameters are specified in a command, they are separated by a comma ",". A few
queries permit the parameters MINimum, MAXimum and DEFault to be entered. Refer
to
on page 279 for a detailed description of the various
parameters.
Example:
SENSe:FREQuency:STOP? MAXimum
Response: 3.5E9
This query requests the maximal value for the stop frequency.
Special Characters
●
Vertical stroke |
A vertical stroke in parameter definitions indicates alternative possibilities in the
sense of "or". The effect of the command differs, depending on which parameter is
used.
Example
–
DISPlay:FORMat SINGle | SPLit
If parameter
SINGle
is selected, full screen is displayed, in the case of SPLit,
split screen is displayed.
A selection of key words with an identical effect exists for several commands.
These keywords are indicated in the same line; they are separated by a vertical
stroke. Only one of these keywords needs to be included in the header of the
command. The effect of the command is independent of which of the keywords
is used.
–
SENSe:BANDwidth|BWIDth[:RESolution]
The two following commands with identical meaning can be created. They set
the frequency of the fixed frequency signal to 1 kHz:
SENSe:BAND 1
SENSe:BWID 1
●
Square Brackets [ ]
Key words in square brackets can be omitted when composing the header. The full
command length must be accepted by the instrument for reasons of compatibility
with the SCPI standards.
