Measurement and Instruments

Signals, filters, and how flowRS talks to laboratory instruments safely.

Who this is for: Test, measurement and lab engineers.

01

Signals and spectra

Acquire, transform, and look at a signal in both domains.

Older IDE Filmed on the IDE as it was in late August 2026. The editor has changed since, so some screens look different. The written walkthrough is current.

  1. Sources, sample rates and buffers.
  2. Time domain against frequency domain.
  3. Reading a spectrum honestly — windows and what they cost you.

Outcome: You can take a signal apart and know what you are looking at.

02

Filter design

The IIR families, what each is for, and zero-phase filtering.

  1. Butterworth, Chebyshev I and II, elliptic, Bessel — the trade each one makes.
  2. Order, cutoff, and reading the response you actually got.
  3. Zero-phase filtering when phase distortion is unacceptable.

Outcome: You can choose and defend a filter for a real measurement.

03

Instrument protocols

SCPI and its transports — and where a language model's authority stops.

Older IDE Filmed on the IDE as it was in late August 2026. The editor has changed since, so some screens look different. The written walkthrough is current.

  1. SCPI as a language, and the framings that carry it.
  2. Setting the instrument's parameters yourself, or letting an agent propose a configuration for you to review.
  3. Constraints, validation, and the deterministic path to the wire.

Outcome: You can compose an instrument program and explain why it is safe to run.
