The HP/Agilent 66321B is a single-output DC power supply engineered for testing digital wireless and battery-powered devices. It delivers precise voltage and current control across a 0–15 V, 0–3 A output range, with peak current capability up to 5 A for 7 ms transients. The instrument combines low output noise (1 mV rms, 6 mV peak-to-peak), fast transient response (<20 µs), and battery emulation features—including programmable internal resistance and negative resistance simulation—making it ideal for mobile device development and system integration.
