Tektronix P6251 TekProbe 1GHz High Voltage Differential Probe

The Tektronix P6251 is a high‑performance 1 GHz differential oscilloscope probe designed for high‑speed differential signal measurement. It features switchable attenuation (÷5 / ÷50), bandwidth selection (Full / 5 MHz), and DC Reject on/off function for flexible signal filtering and testing. Max non‑destruct voltage: ±100 V pk; Common‑mode range: 35 V (DC+pk AC); Differential‑mode range: ±4.25 V (÷5), ±42 V (÷50). Differential input impedance: 500 kΩ || <1 pF, with 50 Ω output termination requirement. Ideal for high‑speed digital circuit testing, power electronics debugging, floating signal measurement and high‑frequency electronic R&D. Used unit in excellent working condition, fully tested, stable and reliable for laboratory measurement applications.
