Advantest V93000 EXA Scale test platform equipment power supply DPS board XPS256

The XPS256 is a Device Power Supply (DPS) module designed by Advantest for the V93000 EXA Scale test platform. Its primary value lies in its ability to cover a vast power-delivery range—from the milliampere level to several thousand amperes—within a single module, catering to the testing of advanced chips such as those used in AI, HPC, and mobile processors.

Core Specifications

Channels and Voltage: Features 256 independent channels, each capable of outputting between -2.5 V and +7.0 V with a maximum current of 1A; supports full four-quadrant voltage and current sourcing.

Precision: Achieves voltage/current sourcing and measurement precision of up to 150 µV and 50 nA, respectively.

Scalability: Supports unlimited channel ganging; a single module can be scaled to deliver over 1000A, while the full module configuration supports an output of 256A at 2V.

Key Features

The module incorporates a background DC Profiling function, enabling zero-overhead monitoring of voltage and current throughout the entire test process. Combined with hardware-based clamping (operating at the 100-microsecond scale), it effectively protects both probe cards and the devices under test (DUTs) from overcurrent damage.
