IEEE-488.2 Programming Manual Requirements

Certain programming requirements are specified for GPIB interfaces by the American National Standard Institute (ANSI) document, ANSI/IEEE Std. 488.2- 1987, which are detailed in this section.

Power-on settings

The GB1400 will restore the device settings to their same values from when it was last powered off. No remote commands affect this. The only exception to this is when the non-volatile RAM becomes corrupted (which should never happen during normal operation). RAM corruption, if it occurs, will be displayed on the unit’s LCD display. When this happens, the GB1400 will revert to its factory-default settings.

Message Exchange

The message exchange options are as follows:

∙The input buffer is command line oriented. There is a new input buffer for each command line or program message. The maximum input buffer length is 80 characters.

∙The only remote commands that return more than one response message unit are: *lrn?; sta?; rdm?; rfm?; all?

∙All queries immediately generate their own response messages when parsed. No queries wait until the responses are read for them to be generated.

∙No commands are coupled.
