IEC 625/IEEE 488 Interface
See
IEC bus (IEEE 488) interface for remote control of the R&S NRT2. Used to connect a
controller to remote control the R&S NRT2. Use a shielded cable for the connection.
Characteristics of the IEC bus (IEEE 488) interface:
●
8-bit parallel data transfer
●
Bidirectional data transfer
●
Three-wire handshake
●
High data transfer rate
●
Up to 15 R&S NRT2s can be connected
●
Maximum length of connecting cables 15 m (single connection 2 m)
●
Wired OR operation with parallel connection of several R&S NRT2s
