US Navy AUTEC Program: Vintage Tektronix 321A Battery Powered Oscilloscope

Description

This Vintage Tektronix 321A Battery Powered Oscilloscope is a piece of equipment retired from the
US Navy's Atlantic Undersea Test and Evaluation Center (AUTEC)
and has been in storage for 20 years since the original auction of Charles Bell's Estate in 2000.
The device measures 15" X 6" X 8".
From the user manual: "The Tektronix Type 321A is a high-performance, dc-to-6 mc, transistorized oscilloscope. Its light weight, small size and ability to operate from a variety of power sources make it a versatile field and laboratory instrument. The oscilloscope can operate from its internally-contained rechargeable battery pack, an external dc source or from a 115/230-volt 50-800 cycle ac line. Regulated power supplies in the instrument, accurate calibration, and precise linearity assure exact time and amplitude measurements despite normal voltage-source and power-supply-load changes that occur under actual operating conditions."
