11.2.2.1 Global Connectors
The R&S SMW is equipped with six USER interfaces which can be freely assigned a
selection of signals and which can be configured as both inputs and outputs.
A common threshold and input impedance is effective for all trigger and clock signal
inputs provided at the global USER connectors. The settings influence the custom digi-
tal modulations, the generation of waveforms or multi carrier signals, and all digital
standards.
Additionally, the R&S SMW is equipped with two INST TRIG X connectors. The instru-
ment trigger setting influences all sweeps and is effective in the List mode (see also
Chapter 7.6, "Varying the RF Signal in List or Sweep Mode", on page 457).
The Table 11-1 gives an overview of the signals that can be applied to and output at
the USER connector.

11.2.2.2 Baseband Local Connectors
Apart from the multipurpose global USER connectors, each baseband coder board is
equipped with local T/M/C connectors.
