Angle brackets < >
Angle brackets (< >) are used to denote a parameter type. Do
not include the brackets in the program message. For example:
RATio <b>
The <b> indicates a Boolean-type parameter is required.
Therefore, to enable channel ratio, you must send the
command with the ON or 1 parameter as follows:
RATio ON
RATIO 1
Query commands
This type of command requests (queries) the presently programmed status. It is identified
by the question mark (?) at the end of the fundamental form of the command. Most
commands have a query form:
TRIGger:TIMer? Queries the timer interval.
Most commands that require a numeric parameter (<n>) can also use the DEFault,
MINimum, and MAXimum parameters for the query form. These query forms are used to
determine the *RST default value and the upper and lower limits for the fundamental
command. Examples are:
TRIGger:TIMer? DEFault Queries the *RST default value.
TRIGger:TIMer? MINimum Queries the lowest allowable value.
TRIGger:TIMer? MAXimum Queries the largest allowable value.
Case sensitivity
Common commands and SCPI commands are not case sensitive. You can use upper or
lower case and any case combination. Examples:
*RST = *rst
DATA? = data?
SYSTem:PRESet = system:preset
NOTE
Using all upper case will result in slightly faster command response times.
