Application note AN003 - Describes the mandatory hot-swap tests required for NVMe Plugfest #4 and later.

Demonstrates how to repeat these tests, and recommends additional testing required to ensure you are compliant.

Demonstrates Python automated control of Power Modules over USB and LAN. This allows platform independent control of the device, with high speed download and streaming of measurement data. This example makes use of the Quarch Instrumentation Server (QIS) and is the recommended method of automating control over Quarch power modules

This may require Firmware updates of your module. QTL1824 (XLC Modules), must be hardware revision -03 or above to run this (Upgrades are possible for earlier units)

The Java based Stream! application allows cross platform USB streaming of data from a PPM, at up to 15k Samples/second.

This example app allows both viewing and saving to CSV file. The source code is available on request.

This may require Firmware updates of your module. QTL1824 (XLC Modules), must be hardware revision -03 or above to run this (Upgrades are possible for earlier units)

This application note includes a simple Excel worksheet that can take streamed Power Module data and allow post processing and graphing. It can re-average data (for instance allowing data to be converted to a 1 second sampling rate) and display a subset of the recorded file.

This application note is specifically for Quarch PCIe modules, though many of the ideas can be translated onto other hot-swap / breaker modules.

A customer requested our help to create a very specific series of events, to replicate an issue they were trying to debug. In this example, we show how we created the series of timed events they required, using the glitch/drive feature of the breaker module.

We demonstrate how to control PERST, REFCLK and 12V_EN in sequence with each other

This is a great starting point to understand glitch and drive logic, and how it can be used in practical tests.

Quarch modules are capable of creating a large number of physical layer faults. These fault scenarios can be used to test the ability of your design to handle likely failures.

This application note is based on creating SAS physical layer errors, but the contents are relevant to all Quarch 'Breaker' modules.

We describe how to create (and automate) fault scenarios such as lane failures, random glitches and more.

Labview can easily hook into the Quarch .NET API to control modules.

This simple example implements selection of a specific module and allows command to be sent to it.
