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.
