special numerical values.
In the case of a query, the associated numerical value is provided.
Example: Setting command:
SOURce:IMPairment:GAIN:I MAXimum
Query:
SOURce:IMPairment:GAIN:I?
Answer: 0
MINimum and MAXimum denote the minimum and maximum value.
DEFault denotes a preset value. This value conforms to the default setting,
as it is called by the *RST command.
UP, DOWN increases or reduces the numerical value by one step. The step
width can be specified via an allocated step command for each parameter
which can be set via UP, DOWN.
INFinity, Negative INFinity (NINF) represent the numerical values
-9.9E37 or 9.9E37, respectively. INF and NINF are only sent as device
responses.
Not A Number (NAN) represents the value 9.91E37. NAN is only sent as
device response. This value is not defined. Possible causes are division by
zero, subtraction or addition of infinite and the representation of missing
values.
Boolean parameters represent two states. The ON state (logically true) is
represented by ON or a numerical value unequal to 0. The OFF state
(logically untrue) is represented by OFF or the numerical value 0. ON or OFF
is returned by a query.
Example: Setting command:
SOURce:EQUalizer:STATe OFF
Query:
SOURce:EQUalizer:STATe?
Answer: 0
Text parameters observe the syntax rules for key words, i.e. they can be
entered using a short or long form. Like any parameter, they have to be
separated from the header by a white space. In the case of a query, the short
form of the text is provided.
Example: Setting command:
SOURce:TRIGger:SOURce MANual
