Command summary
Common commands supported by the Model 2651A are summarized in the following table. Although
commands are shown in upper-case, common commands are not case sensitive, and either upper or
lower case can be used. Note that although these commands are essentially the same as those
defined by the IEEE- 488.2 standard, the Model 2651A does not strictly adhere to that standard.
NOTE
Unlike other commands, such as those in the Command reference (on page 7-1), each common
command must be sent as separate lines.
