Talking to the Instrument
In general, computers acting as controllers communicate with the instrument
by sending and receiving messages over a remote interface, such as GPIB or
RS-232C. Instructions for programming the 1660-series logic analyzers will
normally appear as ASCII character strings embedded inside the output
statements of a "host" language available on your controller. The host
language’s input statements are used to read in responses from the
1660-series logic analyzers.
For example, HP 9000 Series 200/300 BASIC uses the OUTPUT statement for
sending commands and queries to the 1660-series logic analyzers. After a
query is sent, the response can be read in using the ENTER statement. All
programming examples in this manual are presented in HP BASIC.
Example This Basic statement sends a command that causes the logic analyzer’s
machine 1 to be a state analyzer:
OUTPUT XXX;": MACHINE1:TYP E STATE" <termin ator>
Each part of the above statement is explained in this section.
