This range includes high-voltage probes that extend the input range of your scope, and high-frequency probes that boost its input impedance for more accurate measurements.
All active probes require a power supply or batteries. Our battery-powered probes are supplied complete with batteries, while optional AC adaptors are available for the externally powered types. Read our application note: Choosing the right Pico Technology active differential probe.
For making differential measurements from millivolts to 1000 V CAT III also consider the PicoScope 4444 differential input oscilloscope
