Differential Impedance TDR Probe 18GHz, 1X,
Impedance: 50Ohm odd mode, 100Ohm differential
The Tektronix P80318 is an 18 GHz 100 Ω input impedance differential TDR hand probe. This probe enables high-fidelity impedance measurements of differential transmission lines. The adjustable probe pitch enables a wide variety of differential line spacing and impedances. The P80318 probe also includes two precision SMA cables with parallel control lines that provide the 80A02 the control for EOS/ESD protection.
The P80318 probe can be used as a stand-alone high-resolution probe, but it is specially designed to be used with two 80A02 EOS/ESD protection modules.
