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. Tektronix Low Voltage Single-ended Probe solutions offer: Bandwidths up to 4 GHz. Very high input impedance with low input capacitance (
