Accelerate test throughput with industry-leading specifications

• test speeds 100x faster than standard system power supplies
• command processing speed < 2 ms
• fast up / down programming speeds up to 500 µs
• adjustable measurement rate to balance speed and accuracy

Accurately characterize your DUT’s power profile with advanced measurement capability

• dual voltage and current measurement capability with DMM-like accuracy
• power, peak power, watt hour, and amp hour measurements

Full two-quadrant operation for power storage test applications

• provides continuous smooth operation between + current and – current transitions
• Provides + and – programmable current limits, programmable + and – current waveforms, and automatic downprogramming
• full two-quadrant operation requires N7909A power dissipater units; standalone power supply offers 10% rated current two-quadrant operation

Track power events with a black-box recorder

• optional accessory N7908A black-box recorder
• works in the background, tracking power events whenever the auxiliary power supply (APS) is on
• records measurement data, trigger events, status bits, and more
