LEDs
• 1-4: LEDs illuminate when that channel is active
• 5: Status LED is red when scope is first connected to an active USB port. It flashes green when
sampling data and is off when scope has finished sampling data.
Connections
• A: Input channel A
• B: Input channel B
• C: Input channel C
• D: Input channel D
• E: Optional DC power connector for Pico-approved power supply
• F: Ground terminal. A computer power supply could interfere with the scope, causing noise
on the trace or a BNC shell voltage overrange indication. Connecting the rear panel ground
terminal to earth or the chassis ground of the vehicle under test may resolve this.
• G: SuperSpeed USB port. The USB 3.0 port allows fast data transfer and is compatible with
USB 2.0.
