//00 NEEDS

What brings you here.

The situations this instrument was built for — and what it does about each one.

Need 01

Free tools will plot a serial stream — almost none will record it and give it back at the right speed.

Answer

Streamed .tsr recording, and 0.1×–10× timed replay through the same decode path the live data took.

Need 02

Ad-hoc decoding scripts quietly disagree about the wire format.

Answer

One YAML definition states framing, types, endianness and scaling — or the read fails with a line number. Nothing is assumed.

Need 03

A capture has to stay useful years later.

Answer

Recordings keep the raw frames plus timestamps, and the channel definition travels inside the file.

//00 WHAT IT DOES

UDP / serial ingestion with engineering-unit scaling

Streamed .tsr recording, crash-safe

0.1×–10× timed replay through the same pipeline

//00 IN PRACTICE

What you'll see.

Point it at a UDP port or a serial line, hand it a YAML file describing how bytes become numbers, and watch. Capture the session to disk, then play it back at 0.1×–10× through the same decode path the live data took — so what you see on replay is what the capture saw, not a second opinion about it.

The scope, replaying a capture

Many traces, a 5 s – 5 min window, min/max envelope decimation, freeze and cursor read-out. Drag the position slider to scrub; the chart fills with the window leading up to the handle rather than going blank.

Out-of-range readings, flagged as they arrive

Frames are decoded to engineering units against the valid range the definition states. Recordings capture raw frames before decoding, so a capture stays useful even if the definition turns out to be wrong.

Quick answers

Does Telemetry Scope work offline?

Yes. Like every NOKTRA instrument it is offline-first: no cloud services, no telemetry, and any AI runs locally on your own machine. It is built for air-gapped networks.
