Marvin Test Solutions announces new PXI Multifunction instrument
Wednesday, 5 August 2020

Marvin Test Solutions, Inc., a trusted provider of globally-deployed innovative test solutions for military, aerospace, and manufacturing organisations anounced the release of the new GX3722 Series Multifunction Analog and Digital I/O Instrument.

The GX3748 combines 48 voltage comparator channels with windowing and precision level detection, to deliver the ideal event monitoring and control solution. Triggers can be generated, based on user programmable voltage threshold levels, enabling time-critical response when out-of-limit test conditions occur. Additionally, multiple high-density comparator cards can easily be combined in a single chassis without sacrificing performance or system response time, expanding monitoring capacity to many hundreds of channels.

The 50 V input range is ideal for a wide variety of applications, combining 16 channels of comparator window functionality with 32 channels of threshold detection. Signal levels can be monitored on any of the input channels, while event timestamp and the ability to digitize and store data on a single channel per 16 channel group further expands this card's utility.


The GX3722 delivers exceptional flexibility and utility, with a unique mix of measurement and control functionality, in a single high-performance 3U PXI hybrid slot compatible instrument. Analog measurement capabilities include four time-interval channels, each rated at 10 MHz, with channels supporting both 50 omega and 75 omega input impedance. Two digitizer channels, each with a maximum sampling rate of 10 MS/s, include programmable input impedance and sampling rates with a 24 Vpp input range.

Two channels of multifunction waveform generation deliver Sine, Triangle, Sawtooth, Square, and Arbitrary signals up to 10 MHz, while four channels of dedicated square wave generation further complement the source capabilities of this card. The addition of four 100 kHz differential TTL I/O channels and three open collector output channels (50 V, 2.0 A) enable control of external devices.

"The GX3722 delivers a unique combination of measurement and control functionality ideal for small to medium size systems" said Jon Semancik, Director of Marketing for Marvin Test Solutions. "And the ruggedized, extended temperature version is perfect for customers deploying test systems in extreme, harsh environments."

The GX3722 Series is supplied with GxFPGA, a software package that includes a virtual instrument panel, and a Windows® 32/64-bit DLL driver and documentation. Interface files are provided to support access to programming tools and languages such as ATEasy®, LabVIEW, C/C++, Microsoft C# and Visual Basic® .Net. A Linux driver is also provided with the GtLinux software package.
