067-0587-02

Template:Plugin Sidebar 2 The Tektronix 067-0587-02 is a signal standardizer (calibration) plug-in for 7000-series scopes. It is a complete redesign of the 067-0587-01 standardizer. It provides a calibrated staircase at 1 line/Div in Gain mode, a fast-rising pulse in Step Resp mode, an input for a CW signal to test bandwidth, and an input for a common mode test signal.

Input range	0.5 to 1 V_p-p
Flatness	± 3% from 3 MHz to 1 GHz

Internals

The 067-0587-02 is based on a number of Tektronix custom ICs from the 1 GHz 7104 scope generation, such as the 155-0160-00 trigger amplifier + source select chip and the 155-0175-00 trigger amplifier chip.

The mode selector switch is a special elastomer-based cam switch. The manual warns that while it can be cleaned if proper procedure is followed (note some screws are labelled "do not remove" on the cover!), only at the factory can (could ...) it be repaired/re-assembled completely.
