Response Data Types

Character strings returned by query statements may take either of the following forms, depending on

the length of the returned string:

Character Response Data. Permits the return of character strings.

Arbitrary ASCII Response Data. Permits the return of undelimited 7-bit ASCII. This data

type has an implied message terminator.

String Response Data. Returns string parameters enclosed in double quotes.

Response Messages

A response message is the message sent by the instrument to the computer in response to a query

command program message.

Sending a Response Message

After sending a query command, the response message is placed in the Output Queue. When the

electronic load is then addressed to talk, the response message is sent from the Output Queue to the

computer.

Multiple Response Messages

If you send more than one query command in the same program message (see the paragraph entitled,

“Multiple Command Messages”), the multiple response messages for all the queries is sent to the

computer when the electronic load is addressed to talk. The responses are sent in the order that the

query commands were sent and are separated by semicolons (;). Items within the same query are

separated by commas (,). The following example shows the response message for a program message
