3.3.5.4.1 KEYWORD
Keywords are instructions recognized by a decoder within the MBT-G Power Supply, referred to
as a “parser.” Each keyword describes a command function; all keywords used by the MBT-G
Power Supply are listed in Figure 3-4.
Each keyword has a long form and a short form. For the long form the word is spelled out com-
pletely (e.g., STATUS, OUTPUT, VOLTAGE, and TRIGGER are long form keywords). For the
short form only the first three or four letters of the long form are used (e.g., STAT, VOLT, OUTP,
and TRIG). The rules governing short form keywords are presented in Table 3-25.
You must use the rules above when using keywords. Using an arbitrary short form such as
ENABL for ENAB (ENABLE) or IMME for IMM (IMMEDIATE) will result in an error. Regardless
of which form chosen, you must include all the letters required by that form.
To identify the short form and long form in this manual, keywords are written in upper case let-
ters to represent the short form, followed by lower case letters indicating the long form (e.g.,
