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).

Trigger Input Slope
Sets the polarity of the active slope of an applied instrument trigger.
This setting affects the INST TRIG input (BNC connector at the rear of the instrument).
"Positive" The rising edge of the trigger signal is active.
"Negative" The falling edge of the trigger signal is active.

Automatic Delay Compensation
While working in a master-slave mode, the instruments are connected as daisy chain
(see also
​
chapter 5.8.2.4, "Synchronous Signal Generation" , on page 277). The settings
for automatic delay compensation enable each of the slaves to calculate and compensate
the expected timing delay caused by the used cables. The calculation assumes an ordi-
nary BNC cables that have a dielectrics with a permittivity of
Ɛ
r = 2.7.
