If a query has a parameter, insert a space after the question mark and continue to
code a parameter.

Response
A response is made for a query. A response is a message that is always sent from the
device to the computer. The status of a device and measured values are posted to the
computer.
•
When two queries are sent in separate lines, read the response to the first query
before transmitting the second line after reading the first response.
•
GPIB, USB
If two lines of queries are sent at the same time, an SCPI error (-410, “Query
INTERRUPTED”) may occur.
•
RS232C
If two lines of queries are sent at the same time, an incomplete response may
be received and then a complete response may be received.
String termination
Every command must be terminated with a valid terminator.
Terminators include <new line> (ASCII 0x0A) and EOI (end or identify). When
either one is specified, it works as a terminator.
Always use <new line> for the RS232C because EOI is not available.
EOI is not available for USB either. However, a terminator other than <new line> is
automatically assigned. <new line> may or may not be assigned.
When a command string is finished, the path is always reset to the root level.
•
CR (ASCII 0x0D) is not a terminator.
Common commands
The IEEE-488.2 and SCPI standards define a series of common commands used for
resetting and self-diagnosis. Each of the common commands always begins with an
asterisk (*) and may have one or more parameters.
