R&S PR100 User Manual
INF INFinity stands for +^. For queries the numerical value 9,9E37
is output.
NINF Negative INFinity (NINF) stands for -^. For queries the
numerical value -9,9E37 is output. In a measured-value query,
this value is output if the measurement cannot be carried out
(e.g. due to a wrong device setting).
NAN Not A Number (NAN) stands for results of calculations that are
not number. Possible causes are the division by zero, the
subtraction of infinity from infinity and simply missing values..
SCPI outputs the value 9,91E37 where NAN is meant. NAN is
only sent as a device response, it cannot be entered in a
command.
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: SYST:COMM:SOCK:DHCP:STAT ON
Query: SYST:COMM:SOCK:DHCP:STAT?
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: FORMat:BORDer SWAPped
Query: FORMat:BORDer? Response SWAP
Strings
Strings must always be entered in quotation marks (' or ").
Example:
PROGram:PRESet:DEFine “User Preset 1”
PROGram:PRESet:DEFine ‘User Preset 2’
Block Data
Block data (Definite Length Block) are a transmission format which is suitable
for the transmission of large amounts of data. A command using a block data
parameter has the following structure:
Example:
HEADer:HEADer #45168xxxxxxxx
