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.

Active oscilloscope probes

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 whether measuring millivolts or upto 1000V CAT III consider also our PicoScope 4444 differential input oscilloscope

TETRIS 1000 1 GHz high-impedance active oscilloscope probe 10:1

Pico Technology presents a unique Inline Probing System – the TETRIS® active probe. The unique design of the TETRIS active probe allows for contact to adjacent square pins in 2.54 mm pitch simultaneously. This is possible due to the probe's T-shaped housing allowing many probes to be positioned next to each other, permitting multiple measurements to be taken at the same time.

The TETRIS 1000 is independent of any particular system, and with its standard BNC connector it can be plugged into any measuring instrument with a 50 Ω input. With an input resistance of 1 MΩ and an input capacitance of 0.9 pF the TETRIS 1000 probe is suitable for measurements in all frequency ranges. Compared to passive probes the TETRIS 1000 active probe offers a high input impedance into the GHz range. These characteristics make it the ideal probe for most of your daily measurements.

If the measuring instrument does not have 50 Ω coupling, an external 50 Ω terminator can be used (such as a TA051), but the system bandwidth may be reduced.

The TETRIS 1000 probe is shipped with a comprehensive set of accessories and durable soft pouch for safe storage.
