Programmable Power Modules

This module can perform full power margining from 0V to Nominal +20%, with complex voltage ramps, glitches and more. Dual Output channels (12V and either 3V3 or 5V) allow you to power most common devices.

250KHz sampling allows capture of accurate Voltage, Current and Power data. Replace your bench power supplies, scope and current probes with this powerful and cost effective alternative.

New Press Release for Quarch PPMs!

XLC Programmable Power Module

This module can perform full power margining from 0V to Nominal +20%, with complex voltage ramps, glitches and more.

250KHz sampling allows capture of accurate Voltage, Current and Power data. Replace your bench power supplies, scope and current probes with this powerful and cost effective alternative.

The XLC module can perform accurate current measurement at below 100uA, and has 8Mbit of memory buffer. A mode switch allows use with both 5V SAS and 3V3 PCIe devices.

HD Programmable Power Module

This module can perform full power margining from 0V to nominal +20%, with complex voltage ramps, glitches and more.

250KHz sampling allows capture of accurate voltage, current and power data. Replace your bench power supplies, scope and current probes with this powerful and cost-effective alternative.

The HD module can perform accurate current measurement at the same 100uA level as the XLC, has eight times the memory buffer and faster streaming modes.

The modules also support advanced fixtures and LAN control.

Multi-Device Power Testing

Quarch’s latest power module, the HD Programmable Power Module, is a fully programmable power supply and measurement tool for drive power testing.

The HD PPM supports remote control via LAN and a range of advanced power injection fixtures. The new module extends the features of the XLC, with larger recording RAM (eight times the memory depth of the XLC, at 64Mbits) and faster streaming modes. The HD board is also significantly smaller, allowing six modules to fit in a 1U rack mount.

You can use the multi-port, rack-mounted HD PPM to test multiple drives in a large test rack, instead of laboriously bench-testing one drive at a time. In addition, the HD PPM allows you to automate a wider range of tests and integrate power testing into existing test racks.

Quarch Power Studio (QPS)

Quarch Power Studio (QPS) is a unique package for recording and analyzing the power consumption of storage devices. Using Quarch Programmable Power Modules with QPS, you can gain an order of magnitude more power data, and review it quickly and easily.

Automating QPS

Quarch Power Studio (QPS) is a unique and powerful system for capturing and analysing power data from storage devices. Now you can record data for an unlimited time, then easily navigate through it, zooming in to the smallest details.

QPS works with both XLC and HD power modules from Quarch, and can handle multi gigabyte traces from long term captures. The software is built on the Quarch Instrument Server (QIS) platform.

Using Python, we have the ability to automate QPS. This allows you to gather data without user intervention. QPS also supports ‘arbitrary’ data: one or more additional channels of data from a user source, such as IO performance or drive temperature.

In this example, we use Iometer to drive traffic to a device and plot both power and performance as part of a fully automated test. This allows:

• Multiple automated test scenarios to be run, and
• A details analysis package to be created for later review.
