The 067-0587-01 Calibration Fixture is designed to standardize the | |||
horizontal and vertical deflection factors of 7000 series mainframes. | |||
It provides a uniform step calibrated deflection factor, a fast risetime | |||
step response function and a common-mode input test for both the | |||
vertical and trigger systems. | |||
It uses one custom Tektronix IC, the [[155-0078-00]]. The manual says it | |||
is a high frequency push-pull amplifier. | |||
It uses one tunnel diode, the [[152-0177-00]], a 10 mA, 4 pF diode in | |||
a DO-17 package. It also uses 12 Tektronix custom Schottky diodes, part [[152-0442-00]] | |||
(speced as matched pairs) in the tunnel diode pulse shaper and in the CW peak-to-peak | |||
detector. The service manual | |||
calls them "diconnect diodes", physically they look like snap-off diodes | |||
found in other Tektronix fast risetime pulsers. Note that there is a typo | |||
in the service manual for CR80, CR84, and CR85 in the peak-to-peak detector. | |||
