10.2.2.1 Global Connectors
The R&S SMBV100B is equipped with User x 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 User connectors. The settings influence the custom digital mod-
ulations, the generation of waveforms or multicarrier signals, and all digital standards.
The R&S SMBV100B is also equipped with Inst Trig connector. The instrument trigger
setting influences all sweeps and is effective in the List mode.
See Chapter 6.10, "Varying the RF Signal in List or Sweep Mode" , on page 310.
The Table 10-1 gives an overview of the signals that can be applied to and output at
the User connector.
