T7610: Difference between revisions

Revision as of 09:21, 22 January 2022

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 %.
