What data would you acquire with this?

We're appraising the NI USB-6421 for a RoadTest and would appreciate some member input.

It's USB Type-C powered and has analogue and digital IO and 4 counters, analogue input channels with four input range settings between ± 200 mV to ± 10 V. The analogue output channels have an update rate of 250 kS/s/ch at up to ± 10 V.

It's compatible with some free data acquisition software from NI, but also has some professional software to use with it that's also available.

The full product specifications are available below:

  • I would use it to collect synchronized electrical, mechanical, and sensor data, including voltage, current, frequency, RPM, vibration, temperature, digital states, pulse timing, encoder position, startup behaviour, power consumption, and response to generated test signals. It would support automated testing of turntables, speakers, amplifiers, controllers, grounding systems, and other electronics, with the data logged for graphs, comparisons, fault detection, and pass/fail reports.
