WebbFor reference, adding a 10mOhm series resistance between the AC source and the probe input places the BW at around 100GHz, and adding a 2 Ohm series resistance places the BW at around 1GHz. This makes me wonder - how do scope manufacturers actually determine the bandwidth of the probe? Webbfrequency signals sensitive outputs. These probes are referred to as ‘PDN’ probes, because of their effective use in measuring the low and ultra‐low impedances found in Power Distribution Networks. The input impedance of the Picotest probes remain nearly constant over their entire frequency range.
