5.2.3.10 Global Trigger/Clock/External Input Settings
The "Global Trigger/Clock/External Inputs" menu can be opened using the SETUP or
MENU key under the "Setup" menu as well as in all clock and trigger menus of the
"Baseband" function block.
This menu is used to determine the physical characteristics of the input connectors for
trigger, clock and control signals.
The user inputs/outputs (BNC connector and pins of the AUX I/O connector) are
assigned in the dialog
"User Marker AUX I/O" .
A common trigger threshold and input impedance is effective for all trigger and control
signal inputs. The settings influence the digital modulations, the generation of wave-
forms or multicarrier signals, and all digital standards. Irrespective of this, a common
threshold and input impedance is effective for the serial and parallel data input. These
data sources are available for digital modulation ("Custom Digital Modulation").
The instrument trigger setting influences all sweeps and is effective in the List mode.
