E-7
INF
INFinity
stands for +
∞
. For queries the numerical value 9,9E37 is output.
With MSCAN, FSCAN or DSCAN, the INF value 9,9E37 is entered in the result
buffers
MTRACE
and
ITRACE
to mark the end of range.
NINF
Negative INFinity
(
NINF
) stands for -
∞
. For queries the numerical value
-9,9E37 is output. In a measured value query, this value will be output if owing
to the device setting the measurement cannot be carried out.
NAN
Not A Number (NAN) stands for the value 9,91E37.
NAN
is only sent as a
device response. This value is not defined. Possible causes are the division of
zero by zero, the subtraction of infinity from infinity and the display of missing
values (eg with
TRACe[:DATA]?
).
Boolean parameters 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. 0 or 1 is provided in a
query.
Example:
Setting
command:
OUTPut:FILTer:STATe
ON
Query:
OUTput:FILTER:STATe?
Response:
1
Text
Text parameters (character data) observe the syntactic rules for keywords, i.e.
they can be entered using the 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:
SENSe:FREQuency:MODE FIXed
Query:
SENSe:FREQuency:MODE?
Response
FIX
Strings
Strings must always be entered in quotation marks (’ or ").
Example:
SYSTem:SECurity: OPTion "123ABC"
or
SYSTem:LANGuage ’
English
’
