Gen5 PCIe x16 PAM Fixture w/AUX Power (GPU / AI analysis)

Gen5 PCIe x16 PAM Fixture w/AUX Power (GPU / AI analysis)

Part Number: QTL2983

Product Details

GPU / AI analysis: PCIe devices keep increasing in power consumption, and auxiliary power is required for many modern devices.  High power consumption entails high operating costs, high heat output, and the requirement for large power supplies.

Understanding and optimising power consumption can make a huge difference in lifetime operating costs.  The latest generation of GPUs, AI accelerators, FPGA accelerators, and more can benefit from high-quality power analysis testing, and this device makes it simple.

Power Analysis Module Fixtures (PAM Fixtures) are calibrated measurement devices with digital sideband capture. Allows for a detailed investigation of the interaction between the host and device under test.

This fixture allows easy power performance and sideband timing analysis for x16 PCIe devices, running up to Gen5 speeds.  A variety of options will be available for the different AUX power layouts on PCIe devices.

Accurate voltage and current measurements are taken on all power rails, and selected sidebands have digital capture, giving a full picture of host/device interaction. (Now includes REFCLK_LOSS)

High resolution, long-term recording and the choices of visual analysis software and simple python automation make this a very powerful product

This fixture requires a PAM controller to operate.
