Multiple Queries
You can send multiple queries to the instrument within a single program
message, but you must also read them back within a single program message.
This can be accomplished by either reading them back into a string variable
or into multiple numeric variables. For example, you could read the result of
the query :TIMEBASE:RANGE?;DELAY? into the string variable Results$
with the command:
ENTER 707;Results$
When you read the result of multiple queries into string variables, each
response is separated by a semicolon. For example, the response of the query
:TIMEBASE:RANGE?;DELAY? would be:
<range_value>; <delay_value>
Use the following program message to read the query
:TIMEBASE:RANGE?;DELAY? into multiple numeric variables:
ENTER 707;Result1,Result2
Instrument Status
Status registers track the current status of the instrument. By checking the
instrument status, you can find out whether an operation has been
completed, whether the instrument is receiving triggers, and more. Chapter
6, “Status Reporting” explains how to check the status of the instrument.
