Overview
The HP 1652B logic analyzer is a legacy portable test instrument combining a general-purpose logic analyzer with a built-in digitizing oscilloscope. Originally manufactured by Hewlett Packard and now supported by Keysight, the 1652B is widely used in embedded systems development, microprocessor debugging, and digital circuit troubleshooting. This used unit provides cost-effective access to a proven analyzer platform for maintenance, repair, and educational applications.
