The Tektronix TM5003 is a 3-slot mainframe designed to house and power single-width TM500 and TM5000 series modular test instruments. It provides a flexible platform for custom test system configuration, combining manual and programmable plug-in modules on a single benchtop unit. The mainframe integrates a built-in switching DC power supply with electronically regulated outputs, forced-air cooling, IEEE-488 (GPIB) control, and optional rear interface connectivity. Carry handles enable portable deployment across laboratory environments.

– Typical Applications
Benchtop test system integration; modular instrument configuration; automated test cell deployment; field measurement platforms.
– Compatibility & Integration
The TM5003 operates only with single-width TM500 and TM5000 series modules. TM5000 instruments cannot function in TM500 mainframes. GPIB connectivity enables integration into SCPI-controlled test automation frameworks. The optional rear interface board extends inter-module and external system interconnection capability.
