Tektronix TM503 Three-Slot Power Supply Chassis

Description:

The Tektronix TM503 Three-Slot Power Supply Chassis is used to provide regulated power and mechanical housing for up to three Tektronix TM500 Series plug-in test and measurement modules. Commonly installed in electronics laboratories, manufacturing test stations, calibration facilities, research environments, and field service applications where multiple TM500 Series instruments are configured into a compact modular system. Maintenance technicians, calibration engineers, and system integrators use this power supply chassis for instrument expansion, bench test systems, equipment repair, and replacement of legacy TM500 Series power modules.

Applications:

The Tektronix TM503 is designed as a modular mainframe that powers and supports TM500 Series plug-in instruments, including digital multimeters, function generators, counters, power supplies, pulse generators, amplifiers, and calibration modules. Its three-slot configuration enables flexible bench-top test systems for electronics manufacturing, service centers, educational laboratories, product development, and automated test environments where multiple measurement functions are required from a single chassis.
