It has been confirmed by HP officers (in the enthusiast’s forum hpmuseum.org) that previous versions of the HP Prime cannot work together with the Smartstream 410. To be clear, hp Prime revisions A and B, with product code NW280AA, don’t work with the data acquisition unit; and the only version that guarantees to work is revision C, with product code G8X92AA.

By the way: to make the decision easier and safer, we have created a pack with an hp Prime and a Streamsmart 410, guaranteed to work together.
We have also posted a number of Fourier probes here. Please remember that you need a cable for all of them, although you only need at most 4 cables, if you want to measure 4 magnitudes in parallel.
