SCPI Parameter Types

The language defines several different data formats to be used in
SCPI
program messages and response messages.

Numeric Parameters Commands that require numeric parameters

will accept all commonly used decimal representations of numbers
including optional signs, decimal points, and scientific notation. Special
values for numeric parameters like MINimum, MAXimum, and DEFault
are also accepted. You can also send engineering unit suffixes with
numeric parameters (e.g., Mhz or Khz). If only specific numeric values
are accepted, the function generator will automatically round the input
numeric parameters. The following command uses a numeric parameter:
FREQuency {< frequency
Discrete Parameters Discrete parameters are used to program
settings that have a limited number of values (like BUS, IMMediate,
EXTernal). They have a short form and a long form just like command
keywords. You can mix upper- and lower-case letters. Query responses
will always return the short form in all upper-case letters. The following
command uses discrete parameters:
SWEep:SPACing {LINear|LOGarithmic}
Boolean Parameters Boolean parameters represent a single binary
condition that is either true or false. For a false condition, the function
generator will accept "
generator will accept "
instrument will always return "0" or "1". The following command uses a
boolean parameter:
AM:STATe {OFF|ON}
String Parameters String parameters can contain virtually any set of
characters. A string must begin and end with matching quotes;
ASCII
either with a single quote or with a double quote. You can include the
quote delimiter as part of the string by typing it twice without any
characters in between. The following command uses a string parameter:
DISPlay:TEXT <
quoted string
>|MINimum|MAXimum}
" or "0". For a true condition, the function
OFF
" or "1". When you query a boolean setting, the
ON
