P6230-rt1.jpg | P6230 Rise time measured on a [[7S12]] with [[S-52]] and [[S-4]] heads, P6230 ground sleeve connected directly at S-52 output (no ground lead) | |||
P6230-rt2.jpg | P6230 Rise time without ground lead: 9.2 * 20 ps = 184 ps (equiv. to 1.9 GHz bandwidth) | |||
P6230-rt3.jpg | Effect of using the "low inductance" ground lead - rise time 400 ps, bandwidth 875 MHz | |||
P6230-rt4.jpg | Using the 250 mm alligator ground lead - severe pulse distortion, rise time ~3 ns (115 MHz)! | |||
