Interface Capabilities
The interface capabilities of the oscilloscope, as defined by IEEE 488.1, are
SH1, AH1, T5, L4, SR1, RL1, PP0, DC1, DT1, C0, and E2.
Command and Data Concepts
The interface has two modes of operation:
•
command mode
•
data mode
The bus is in the command mode when the ATN line is true. The command
mode is used to send talk and listen addresses and various bus commands,
such as a group execute trigger (GET).
The bus is in the data mode when the ATN line is false. The data mode is
used to convey device-dependent messages across the bus. The
device-dependent messages include all of the instrument commands and
responses.
