The USB-6421 is a USB Type-C bus-powered mioDAQ device with analog I\/O, digital I\/O, and four counters. It features analog input channels with four input range settings from \u00b1 200 mV to \u00b1 10 V, and analog output channels that can output \u00b1 10 V with update rates of 250 kS\/s\/ch. Additionally, the USB-6421 digital I\/O channels can function as static input or output channels, hardware-timed channels up to 10 MHz, or as triggers, clocks, or I\/O for the four onboard counters. The USB-6421 also supports FlexLogger Lite, free data acquisition software from NI, and includes documented APIs and examples for LabVIEW, Python, C\/C++, and more.<\/p>\n
