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.

Passive oscilloscope probes

Our ergonomically designed passive oscilloscope probes are suitable for use with all major brands of oscilloscopes as well as the PicoScope range of USB Oscilloscopes. Passive probes don't require a power supply or batteries so are lightweight and easily portable.

250 MHz high-impedance passive probe 1:1/10:1 with BNC

The TA131 is 250 MHz low-cost, general-purpose passive high-impedance oscilloscope probe designed for use with oscilloscopes. It is calibrated to work effectively with instruments that have an input impedance of 1 MΩ. A two-position slide switch on the probe handle allows the attenuation ratio to be switched between 10:1 and 1:1. The small box adjacent to the BNC plug contains two adjustable resistors that enable high-frequency trimming.

The probe is equipped with a basic accessory pack including a retractable hook tip, compensation adjustment tool, IC insulation cap, insulating cap, a ground spring, BNC adapter and a ground lead.
