The sampling LED will be red when scope is connected but not operating. It will
flash green when the scope is sampling data.
When in normal operating mode the channel LEDs on the front panel of the scope
are off.
Ground terminal
It may be on occasion that a computer power supply interferes with the oscilloscope,
causing noise on the trace or a BNC shell voltage overrange indication. Connection
of the rear panel ground terminal to earth or the chassis ground of the vehicle
under test will resolve this problem.
SuperSpeed USB
The SuperSpeed USB 3.1 port allows fast data transfer and is compatible with USB
2.0.
