The measurement handbook

Evidence and methodology

Sources, calculations and physical tests carry different kinds of evidence.

Three labels, with distinct meanings

Source-based guide
An explanation grounded in linked technical documentation or attributed external work. It does not mean ScopeBench has reproduced an experiment.
Calculated example
A result from a stated formula and assumptions. Our tools and diagrams identify their model and limits; an ideal curve is not an instrument capture.
Bench-tested
Reserved for a future physical test with a documented setup and supporting records. No launch page claims this label as its evidence status.

How we use sources

We link the specific page supporting a claim, identify its publisher and preserve the distinction between manufacturer documentation, independent experiments and review material. External authors’ measurements remain theirs. A product description is not a test. Consulted sources are not proof that search engines or AI systems cite ScopeBench.

What an original test must include

A publishable test needs its question, circuit and operating state; instrument and firmware; probe and reference connection; input, sample, memory and trigger settings; raw files where available; repeat observations; and limitations. Calculated expectations are kept separate from observed readings. The recording guide and templates define these fields.

References and uncertainty

A more expensive instrument is not automatically ground truth. Accuracy comparisons require a relevant reference, its calibration or uncertainty basis, and a method whose own errors are understood. Without those, we describe relative observations and do not claim calibrated performance. Fast-edge tests may require equipment beyond an entry-level bench.

Publication and revision

Sources and editorial content were reviewed for this edition on 22 September 2026. A revision date changes when content is substantively reviewed, not on every build. Missing information is labelled as unknown. We correct inaccurate claims and retain the conditions needed to understand an earlier result.
