Tektronix P7225

Accurate high-frequency, low voltage measurements.
A low voltage single-ended probe is typically used for measuring high-speed, ground referenced signals up to 12 V. These low voltage probes are the best choice for making measurements on high impedance, high frequency circuit elements which require minimal probe loading. Users should select probes with a low input capacitance specification (~1 pF) to minimize the probe’s loading effect on the circuit. A probe with lower input capacitance will offer higher input impedance at higher frequencies.
