Computer Interfacing<br />
4.1 General Guidelines<br />
The 2832-C has two computer interface ports: GPIB and RS-232C. The GPIB<br />
port conforms with the IEEE Standard 488.1 hardware standard and the IEEE<br />
488.2 software standard. The protocol for the RS-232C port conforms as<br />
much as possible to the IEEE 488.2 software standard.<br />
As specified by the IEEE 488.2 standard, there are two command types; device<br />
independent commands and device dependent commands. The device<br />
independent commands have the same meaning to all devices and are defined<br />
as part of the IEEE 488.2 standard. All device independent commands start<br />
with an asterisk (*). Device dependent commands do not start with an<br />
asterisk and have meanings unique to the Model 2832-C. A query is a command<br />
that invokes a response from the meter. All queries are terminated by a<br />
question mark (?). It is recommended that when a query is made, that the<br />
response to that query be read before other commands are issued. When a<br />
query is made to the GPIB interface, the MAV bit in the status byte should be<br />
checked by means of a serial poll to make sure that the data is available<br />
before reading the response. (See Appendix C.4 Status Byte)<br />
4.2 Computer Interface Terminology<br />
Listed below are key abbreviations and concepts used in the command<br />
reference section of this manual.<br />
Delimiting Punctuation<br />
For the purposes of this manual, any string enclosed by is considered to<br />
be a command, a string or a numerical argument. The punctuation is<br />
used to symbolize the typographic limits of the command, string or argument<br />
in question.<br />
End or Identify<br />
An IEEE 488.1 signal sometimes sent with the end-of-string character.<br />
Individual Status<br />
This status is generated by the status byte and parallel poll enable register. It<br />
is used in responding to parallel polls.<br />
