EVRA Series (Extended Voltage Range Adapters)
Challenge: When selecting data acquisition hardware, test systems engineers optimize against three competing parameters: precision, sample rate, and voltage range. When [precision + sample rate] are important, we might reach for a DAQ card. Conversely, oscilloscopes provide [sample rate + voltage range] while DMMs supply [precision + voltage range].
In other words, of the three core measurement metrics, we could historically choose two.
Solution: Introducing the EVRA series, which offers 16-bit precision, 2 MS/s sample rate, and up to ±300 V range... across 8, differential channels with 0.1 % linearity. EVRA modules are attached as front ends to NI PXI FlexRIO cards, so channels can be synchronized across modules and custom programmed via the FlexRIO FPGA.
