5.6 Communication on Data Lines
The GPIB bus is the most common remote interface for measuring instruments. It has
also been implemented in the R&S NRP2. The remote controller and the R&S NRP2
communicate by means of messages. The messages sent on the data lines (chapter A,
"Remote control interfaces", on page 349) can be divided into two groups:
●
Interface messages
●
Device-dependent messages
5.6.1 Interface Messages
Interface messages are transmitted on the data lines of the IEC/IEEE bus when the ATN
control line is active. Interface messages allow the controller and the instrument to com-
municate and can only be sent by a controller which serves as the IEC/IEEE-bus con-
troller. Interface commands can be further classified as:
●
common commands
