Since 1991 we have been supplying the world with test and measurement equipment. At Pico we realize that your choice of test accessories can be almost as important as your choice of test equipment. Here you can purchase a variety of test and measurement accessories quickly and securely online.
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
The TA044 is an active differential probe suitable for high common-mode voltage measurement applications up to ±7000 V (DC + peak AC).
This differential probe extends the functionality of standard single-ended input oscilloscopes to allow a safe and accurate method of making high-voltage differential measurements. Applications include making safe measurements in power circuit applications and acquisition of low-speed balanced differential signals found in serial communications buses.
