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 ...
7104 rise time measurement. 150 ps risetime pulse from 067-0587-02 at 100 Hz repetition rate. Measured 240 ps (corrected for 150 ps fixture rise time: 190 ns = 1.8 GHz)
7104 rise time measurement as before, 1000 Hz repetition rate at same brightness settings.
7104 recording a single shot pulse (from 067-0587-02) at 200 ps/Div. Camera: Nikon D7000, 50 mm f/1.4, ISO 3200, 1/2 s. CRT filter not removed.
7104 recording 1 GHz sine, single shot at 500 ps/Div. Camera: Nikon D7000, 50 mm f/1.4, ISO 3200, 1/2 s. CRT filter not removed. CRT amplification loss is evident around the center line.

P6202 rise time measured with 7S12, S-4, S-52
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 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)!
