Rear panel connectors for the first RF path (option R&S SMW-B81/-B83) and the sec-
ond RF path (option R&S SMW-B82/-B84). These options are recommended for use of
the instrument in a 19" rack.
See also "Mounting in a rack" on page 40.
IEC 625/IEEE 488
GPIB-bus interface for remote control of the instrument.
The IEC 625 interface is in compliance with IEEE488 and SCPI. A computer for remote
control can be connected via this interface. To set up the connection, we recommend
that you use a shielded cable.
Note: To avoid electromagnetic interference (EMI) caused by open lines, always termi-
nate any connected IEC-bus cable with an instrument or a controller.
See also Chapter E.1, "GPIB-Bus Interface", on page 1241 and Chapter 12, "Network
Operation and Remote Control", on page 702.

Input/output for external reference signal.
The external reference is used for both paths.
See Chapter 7.4, "Reference Oscillator", on page 441.
INST TRIG X
Input for external trigger of sweeps and list mode.
For detailed information on the sweep modes and the triggering, see Chapter 7.6.1,
"Signal Generation and Triggering in the Sweep and List Modes", on page 459.
