466

Manuals – Specifications – Links – Pictures

The Tektronix 466 is a portable 100 MHz dual-trace CRT storage scope with dual time bases.

It is similar to the 465, but with a transfer storage CRT. Thanks to its reduced scan feature, it allows much faster storage than its 464 sibling.

Like the 465, it could be ordered with either a DM40 digital multimeter or DM43 (or the later DM44) multimeter with temperature.
