Faster-than-light beam on 7104? Using a 067-0587-02 calibration fixture at maximum amplitude produces this trace spanning 1.2 Div horizontally at 200 ps/Div and 8 Div vertically. Trace length is (1.2² + 8²)½ × 8.5 mm = 68.8 mm, travelled in 1.2 × 200 ps = 240 ps. Apparent speed is therefore 68.8×10-3 / 240×10-12 m/s or 2.86×108 m/s. Very near miss ...

P6230 Rise time without ground lead: 9.2 * 20 ps = 184 ps (equiv. to 1.9 GHz bandwidth)
-
P6230 Rise time - Effect of using the "low inductance" ground lead - rise time 400 ps, bandwidth 875 MHz
-
P6230 Rise time - Using the 250 mm alligator ground lead - severe pulse distortion, rise time ~3 ns (115 MHz)!
