Pico Technology USB Cables feature USB 3.0 and 2.0 specifications and lengths ranging from 0.5m to 4.5m. These cables utilize 20AWG conductors for minimal resistance. This also reduces the risk of voltage drop caused by inferior USB ports on some PCs and laptops. Pico Technology USB Cables prevent noise that could be caused by an unreliable ground connection and poor screening in inferior cables. The USB 3.0 cable comes in a 1.8m length and is designed and built specifically for use with USB 3.0-connected PicoScope oscilloscopes. The USB 2.0 cables range in length from 0.5m to 4.5m and are designed and built specifically for use with PicoScope oscilloscopes. The 0.5m cable is ideal for field applications or for simply reducing clutter in the work space.
