The Tektronix T7610 (P/N 154-0784-00, 154-0784-01) is a coding tube, i.e. a CRT with electronic output.
It was developed for the 7612D 80 MHz digitizer which had a nominal sampling rate of 200 MS/s.
According to the "Special CRTs" paper linked below,
- The equivalent maximum fullscale sine wave at the input [...] is 15 MHz for 8 bit, 20 MHz for 7 bit, and 60 MHz for 6-bit resolution.
- The 3 dB point in the rolloff due to [beam] transit time occurs at 450 MHz. At 100 MHz, deflection sensitivity has decreased by 2.1 %.
