Chapter III Vertical System
This oscilloscope provides 4 analog input channels CH1
CH4, and each channel can be separately controlled.
The vertical system is mainly used to decrease the large signal and increase the small signal, so as to satisfy the
requirements of the ADC input scope.

When any channel key CH1
CH4 is pressed down, the menu of the corresponding channel will pop up at the
bottom of the screen:

Probe
3.2.1 Probe port
There are 4 analog channels on the front panel of the 4456 series digital oscilloscope, which have 4 BNC input
connectors. To ensure reliable connection, ensure that your probe or cable connector is pushed in and locked.
This oscilloscope supports passive voltage probe, high voltage single end probe, high voltage differential probe,
current probe and active voltage probe. When the passive voltage probe, high voltage single end probe, high
voltage differential probe and current probe are used, the input impedance of the oscilloscope shall be set to 1 MΩ
and the probe attenuation coefficient shall be consistent with that of the selected probe. When the active voltage
probe is used, the input impedance of the oscilloscope shall be set to 50Ω and the probe attenuation coefficient
shall be consistent with that of the selected probe.
