Product Information

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.

Features

This XLC Power Module is a flexible power margining and measurement tool. This version has 12V and 5V (switchable to 3V3) outputs and is ideal for SAS, SATA and PCIe based devices. Each rail can be programmed from 0 to 120% of its nominal voltage. The voltage and current of each output can be simultaneously recorded to provide accurate power consumption measurement.

The module allows programming of arbitrary voltage output waveforms which can be used to simulate power-up ramps, power failures, noisy power sources, and much more. Patterns can be created over a range of microseconds to minutes, allowing a wide range of testing options.

A high speed record feature provides an oscilloscope like function to record the output voltage, current, and power consumption of the attached device.

A range of Injection Fixtures allow the module to inject power into a variety of devices.

The QTL1824 version of the module includes external triggering, ideal for co-ordinating with an external analyser

Product Variants

QTL1847 - Basic Version

The standard version of the module

QTL1824 - Triggering Version

This version includes SMA trigger IN/OUT connections, to link to external test equipment, such as an analyser. This allows you to begin power disruptions or measurement at a precise time within the data stream. Similarly, you could trigger the analyser to record based on a signal from the Power Module; Such as the power consumption passing a set threshold.
