Bandwidth, channel count, sample rate, accuracy class, interface. Buyers here are comparing instruments across a handful of parameters with real trade-offs between them. They abandon a selector that asks questions in the wrong order.
Evaluation interest captured separately from a pricing request, and tracked as its own lead.
In most technical catalogs a sample request is a useful early signal. In test and measurement it is often the decisive step: the instrument gets evaluated on a bench against a specific application, and the evaluation decides the purchase. Treating that request as just another form submission throws away the most important event in the funnel.
The second difference is that buyers compare across trade-offs rather than filtering to an exact match. Bandwidth against channel count against price is a judgement, not a filter, which is why a side-by-side comparison matters more here than a longer list of filters.
Instruments side by side on the parameters that trade off, with differences highlighted rather than implied.
The questions an application engineer would ask, in the order they would ask them, ending in a shortlist.
Demo units and evaluation requests handled separately from pricing enquiries, with their own routing and their own follow-up.
Buyers arrive with a measurement problem, not a product category. The catalog should accept that as an entry point.
Every sample request is a tracked lead.
Engineers select by attributes, not by category tree.
