Introduction
Computers communicate with the instrument by sending and receiving
messages over the HP-IB bus. Programming commands are normally sent
as ASCII character strings embedded inside output statements of your
programming language. Input statements are used to read in responses from
the instrument.
For example, HP 9000 Series 200/300 BASIC uses the
OUTPUT
statement for
sending commands and queries. After a query is sent, the response is usually

Introduction
Program Message Terminator
The instructions within the program message are executed after the instruction terminator is received.
The terminator may be either a New Line (NL) character, an End-Or-Identify (EOI) asserted, or a
combination of the two. All three ways are equivalent. Asserting the EOI sets the EOI control line low
on the last byte of the data message. The NL character is an ASCII linefeed (decimal 10).
The NL (New Line) terminator has the same function as an EOS (End Of String) and EOT (End Of Text)
terminator.

Sending Commands to the Instrument
It's easy to send a command to the instrument. Simply create a command
string, and place the string in your program language's output statement. For
commands other than Common Commands, include a semicolon (;) before
the subsystem name.For example, the following string sends the DELAY
command in the Timebase subsystem.

Sending common
commands
You can send commands and program queries from dierent subsystems on
the same line. Simply precede the new subsystem by a semicolon (;) followed
by a colon (:). In the following example, the colon before CHANNEL1 allows
you to send a command from another subsystem.
OUTPUT 707;":TIMEBASE:REFERENCE CENTER;:CHANNEL1:OFFSET 0"
If a subsystem has been selected and a Common Command is received by the
instrument, the instrument remains in the selected subsystem. For example,
