The Agilent/Keysight N3280A is a compact, four-output bipolar DC source engineered for component testing in Automated Test Equipment (ATE) environments. Delivering 5 W across four isolated outputs, this instrument excels in low-power RF and mixed-signal semiconductor characterization. The N3280A reduces test time by at least five times compared to previous Agilent DC sources through optimized command processing and measurement acquisition, while its half-rack form factor minimizes physical footprint in multi-site test scenarios.
