USB 1.1. An early version of the USB standard, found on some older PCs. PicoScopes will operate slowly using a

USB 1.1 port; performance will be greatly improved by using the recommended USB 3.0 port.

USB 2.0. A USB 2.0 port uses signaling speeds of up to 480 megabits per second and is backwards-compatible

with USB 1.1.

USB 3.0. A USB 3.0 port uses signaling speeds of up to 5 gigabits per second and is backwards-compatible with

USB 2.0 and USB 1.1.

Vertical resolution. A value, in bits, indicating the precision with which the oscilloscope converts input voltages to

digital values. The resolution enhancement function in PicoScope can improve the effective vertical resolution.
