The October 2026 Ad of the Month is titled “Engineering Expression at Tektronix.” It was published on February 18, 1962 in The Oregonian in honor of Engineer’s Week. The photos feature Tektronix engineers demonstrating several oscilloscopes: the Type 567 sampling scope at the upper left, the Type 545 in the upper right, a Type 533 at the lower right and a Type 535 in center right. On the lower left there is a Type 315 (upside down) being calibrated using what appears to be a Type 533. At the center left, an unidentified transistorized scope is shown. In addition, the iconic east-facing entrance to Building 81 at the Sunset Plant is found at the bottom. During the 1950s a sketch of the entrance was on the letterhead of Tektronix stationery.
