USB. Universal serial bus.
A standard port that enables you to connect external
devices to a computer.
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 2.0 or 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 can enhance the effective vertical resolution.
Voltage range.
The range of input voltages that the oscilloscope can measure. For
example, a voltage range of ±20 V means that the oscilloscope can measure voltages
between -20 V and +20 V. Input voltages outside of this range will not be measured
correctly. However they will not damage the instrument as long as they remain within
the overvoltage protection range stated in the specifications.
