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 wave-
forms or multicarrier signals, and all digital standards. These data sources are availa-
ble 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 base-
band section.
The setting affects the TRIGGER input and the CLOCK IN/OUT connectors (BNC con-
nectors at the rear of the instrument).
Remote command:
[:SOURce]:INPut:TRIGger:LEVel on page 744
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).
Remote command:
[:SOURce]:INPut:TRIGger:IMPedance on page 743
Impedance Clock Input
Selects the input impedance for the clock inputs. 1kOhm/GND should be selected for
high clock rates.
The setting affects the CLOCK IN connector (BNC connector at the rear of the instru-
ment).
