Tektronix T922 15MHz 2-Channel Portable Oscilloscope For Parts

The Tektronix T922 is a 15MHz, 2-channel analog portable oscilloscope from Tektronix's T900 series — a compact, self-contained bench instrument designed for general-purpose waveform measurement and signal analysis. This unit is being sold AS-IS for parts or repair. Channel 2 produces no trace on the display, and the Channel 1 VOLTS/DIV knob has failing internal contacts that cause readings to jump erratically. It is not in working order and is not guaranteed functional.

Applications

The Tektronix T900 series oscilloscopes were introduced in the 1970s as affordable, portable alternatives to Tektronix's larger laboratory instruments, targeting field service technicians, educational institutions, and small electronics labs. The T922 specifically was designed for general-purpose signal observation up to 15MHz — well-suited for audio, low-frequency RF, power supply ripple, and digital logic work of that era. The portable enclosure with integrated handle made it practical for bench or field use without a separate cart. Today, T900-series Tektronix scopes are sought by vintage electronics collectors, repair technicians sourcing spare parts, and hobbyists who restore classic test equipment. A unit like this with documented faults is a good candidate for repair by someone familiar with Tektronix analog oscilloscope circuits, or as a source of knobs, CRT assemblies, switches, and other components compatible with the T900 family.
