Programming Getting Started

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 and then display

them:

ENTER 707;Result1,Result2

PRINT 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.
