The HP/Agilent 66332A is a 100 W dynamic measurement DC source engineered for characterizing devices under pulsed and dynamic load conditions. Delivering 0–20 V and 0–5 A with peak current capability to 5 A for up to 7 ms, it excels at measuring battery drain and current transients in mobile communications equipment. The instrument combines high-speed programmable output with accurate voltage and current readback, enabling precise waveform capture during rapid load changes. Its transient response of less than 100 µs and settling time of 2 ms (fast mode) support applications requiring fast source transitions. Output noise and ripple measure 3 mVpp, ensuring clean supply rails for sensitive measurements.
