High-power for complex, high-speed production test
Keysight Expert ATE power supplies come in two classes. The NS1-class includes the DP5700 Series, and the NS4-class includes the RP5900 Series. They deliver the precision, speed, and enhanced programmability required to safely test complex systems. The Expert Series architecture delivers fast dynamic response, precise control, and efficient energy recovery, optimized for demanding ATE environments that require dynamic load testing. Choose one of our popular configurations or configure one specific to your application.

Frequently asked questions
Output sequencing is a feature that allows users to program a series of voltage or current steps over time, ensuring a precise and automated power delivery sequence. This is crucial for simulating real-world operating conditions, such as power-up and shutdown sequences in complex electronic systems. Key benefits include:
1. Simulating real-world startup conditions
Many electronic devices require a specific power-up sequence to function correctly. For example, microprocessors, FPGAs, and multi-rail circuits must receive power in a controlled order to avoid damage.
2. Preventing inrush current & power surges
Gradually ramping up voltage and current helps prevent unexpected power spikes that could damage sensitive components.
3. Automating test procedures
Engineers can define complex voltage/current profiles without manually adjusting power settings. This is useful in automated test setups, manufacturing, and reliability testing.
4. Ensuring compliance with power standards
Many industry standards specify strict power sequencing requirements for telecommunications, automotive electronics, and industrial systems.
Yes. Most system power supplies support remote control through interfaces like LAN (Ethernet), USB, and GPIB. They often use standard programming languages (like Python, C++, or LabVIEW) with SCPI commands for automation.
System power supplies utilize fan-based cooling with intelligent thermal management to regulate temperature and maintain optimal performance. These cooling mechanisms ensure efficient heat dissipation to prevent overheating and extend the lifespan of internal components.
Most system DC power supplies often include built-in functions for creating custom voltage / current ramps, pulses, or sine waves, enabling users to test how their devices respond to varying power conditions.
