5.2.3.12 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.
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 waveforms
or multicarrier signals, and all digital standards. 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.
Threshold Trigger/Clock Input
Sets the high/low threshold in volts for the trigger and clock signal inputs of the baseband
section.
The setting affects the TRIGGER input and the CLOCK IN/OUT connectors (BNC con-
nectors at the rear of the instrument).
SCPI command:
[:SOURce]:INPut:TRIGger:LEVel on page 635
Impedance Trigger Input
Selects the input impedance for the external trigger inputs. 1 kOhm/GND should be
selected for high clock rates.
The setting affects the TRIGGER input connector (BNC connector at the rear of the
instrument).
