New GX3748 Series 48-Channel Threshold Comparator Card Delivers Exceptional Event Monitoring Capability


Exceptional Capability with FPGA Configurability
Marvin Test Solutions’ new 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.  

The GX3748 is a user configurable, FPGA-based, 3U PXI card. The daughter board interfaces to the GX3700 FPGA baseboard which employs the Altera Stratix  III FPGA.  Each input channel can accept input voltage signals from 0 to 50 volts, with programmable threshold levels. Three of the 48 channels are supported by the board's timestamp event feature.

No-Compromise Features
The GX3748 Series is the ideal solution for applications requiring simultaneous monitoring of 10’s to 100’s of channels, coupled with the ability to respond rapidly when an event occurs. The ability to modify the instrument’s functionality, utilizing user programmable FPGA tools, further extends the no-compromise features of this card.

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 GX3748 Series is also available in a ruggedized, conformally coated version (GX3748-M) for use in harsh environments.
