FAQ

Product-specific questions

Product-specific answers based on available technical information.

What signals does the NI WSN-3202 measure?

It measures four single-ended analog voltage input signals through a 16-bit ADC. Nominal ranges are ±10 V, ±5 V, ±2 V and ±0.5 V.

Can its digital channels be used as outputs?

Yes. NI documents four bidirectional channels that can be configured for input, sourcing output or sinking output.

Does the WSN-3202 work without a WSN gateway?

A compatible NI WSN gateway is needed to operate the node as part of a wireless measurement network.

Does the calibration manual mean the offered unit is calibrated?

No. The manufacturer document describes a verification procedure; a particular unit’s calibration status must be confirmed separately.
