The difference is voltage setting resolution: UDP3305S has 1 mV resolution; UDP3305S-E has 10 mV. For embedded prototyping, sensor characterization, and analog work where setpoint precision is part of the measurement budget, the UDP3305S Performance tier is the target. For teaching labs, multi-station deployments, and R\u0026amp;D benches where 10 mV resolution suffices, the UDP3305S-E is the same hardware at 10 mV resolution (the Education variant of the Performance Series).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-faq-item\"\u003e\n\u003cp class=\"product-faq-question\"\u003e\u003cstrong\u003eIs the front-panel USB port a data interface?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo — the front-panel USB-A connector on CH4 is a fixed 5V\/2A USB charging output for powering devices under test directly.
