Figure 1-6 Ground loop
The handheld scope input channels, external trigger, USB, and AC/DC adapter
are electrically isolated from each other. This level of isolation allows you to:
– measure floating signal between channels without any unwanted ground loops.
– latch trigger points freely on the circuit.
– connect to the PC using the USB port for monitoring as the port is isolated
from the handheld scope.
– monitor your device-under-test while charging the handheld scope.
Figure 1-7 outlines the handheld scope channel isolation. The chassis and the
controls of an isolated-input channel are designed with plastic, rubber, or other
types of insulating material. Each input channel (CH1, CH2, and Ext. Trig) is
isolated with Keysight isolation technology architecture and the ground leads are
referred to any ground potential as shown in Figure 1-7.

V2
V1
Input 1 Input 2
+– –+
Input 1 and Input 2 negative terminals will experience a V2 potential difference between them.
If these input terminals are not isolated , there will be a short-circuit for voltage source V2.
