Table 4–1 GPIB Command Terminator
A terminator informs GPIB that it has reached the end of statement.
Normally, this is sent automatically by your GPIB programming
statements. In this manual, the terminator is assumed at the end of
each example line of code. If it needs to be indicated, it is shown by
symbol (nl); which stand for “new line” and represents ASCII code byte
the OA Hexadecimal or 10 decimal.
Semicolon ”;“ :The semicolon “;” is a back-up command, the semicolon allows you to
combine command statements on one line to create command
message.
Table 4–2 presents a summary of the GPIB/RS-232 Setting commands, and Table 4–3
