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 ...
