Eddy Current Testing

Fox Eddy

Eddy-current signal analysis on the impedance plane, with I/Q strip charts.

Fox Eddy opens eddy-current data from CSV files and its own .foxeddy sessions, or starts on a clearly labelled synthetic training simulator, so no instrument is needed to try it. It shows each channel on the impedance plane with linked I/Q strip charts, groups threshold events into candidates for the analyst to review, and writes HTML and PDF reports, fully offline on current Windows.

  • CSV

    CSV import and export.

  • Plane

    Impedance plane with linked I/Q strip charts.

  • Review

    Threshold candidates with analyst disposition.

Fully offline, on current Windows, and no instrument is needed to try it: it starts on a clearly labelled synthetic training simulator.

01Data In, Data Out

How a Signal Moves Through Fox Eddy

Fox Eddy takes a CSV file, a saved .foxeddy session or its synthetic training simulator, and sends out an HTML or PDF report, a CSV export or a .foxeddy session.

  • Data in

    A CSV file, a saved .foxeddy session or the synthetic training simulator.

  • 1 Impedance plane

    Each channel on the impedance plane, with linked I/Q strip charts that follow one cursor.

  • 2 Gain and filters

    Set the gain and filters.

  • 3 Candidates

    Threshold events grouped into candidates, each with an analyst disposition.

  • 4 Report

    The inspection details, the processing used and the indication records.

  • Data out

    An HTML or PDF report, a CSV export, or a .foxeddy session that keeps the raw I/Q data.

    • PDF report
    • HTML report
    • CSV export
    • .foxeddy session
02The Toolset

From the Signal to a Report

Grouped the way an eddy-current recording is worked through.

Open the Data

Open a CSV file or a saved .foxeddy session, or start on the clearly labelled synthetic training simulator, so no instrument is needed to try it.

  • CSV import
  • .foxeddy sessions
  • Training simulator
  • Synthetic I/Q

Impedance Plane

Read each channel on the impedance plane with linked I/Q strip charts: one cursor on both, moved with the mouse or the arrow keys, with zoom and peak selection.

  • Impedance plane
  • I/Q strip charts
  • Linked cursor
  • Zoom
  • Find peak

Channel Processing

Set the gain, phase rotation, balance and moving average of each channel, normalise the display to a reference point, and apply first-order high- and low-pass filters.

  • Gain
  • Phase
  • Balance
  • Moving average
  • Reference normalisation
  • High-pass
  • Low-pass

Candidates and Disposition

Group threshold events into candidates by amplitude, minimum duration and merge gap, stage them for review, and record the analyst's disposition and reasoning. The analyst decides what each one is.

  • Amplitude threshold
  • Minimum duration
  • Merge gap
  • Candidates
  • Analyst disposition

Sessions and Replay

Save and reopen sessions as .foxeddy files that keep the raw I/Q data with the analysis, checked with SHA-256 against accidental corruption, and replay a recording at 0.25× to 4×.

  • .foxeddy
  • Raw I/Q kept
  • SHA-256 check
  • Replay 0.25× to 4×

Reports and Export

Write the report as HTML or PDF, with the inspection details, the processing used and the indication records, and export the raw data as CSV.

  • HTML report
  • PDF report
  • CSV export
03How a Recording Is Worked

Open → Review → Report

The order an analyst works in, from the data to the report.

Open

Open a CSV file or a .foxeddy session, or start on the clearly labelled training simulator.

Adjust the channels

Set gain, phase rotation, balance and filters for each channel, and read it on the impedance plane and the strip chart.

Review candidates

Set the threshold, duration and gap, stage the candidates, and record a disposition and the reasoning for each.

Report

Save the session, write the report as HTML or PDF, and export the raw data as CSV.

04Platform

Open Files, Fully Offline

Fox Eddy keeps its data in documented files and runs without a network connection.

CSV

Data in

Opens its documented CSV format and .foxeddy sessions, up to 120,000 samples.

4

Output formats

HTML and PDF reports, CSV export, and .foxeddy sessions.

I/Q

Raw data kept

A .foxeddy session keeps the raw I/Q records next to the analysis, with a SHA-256 check that detects accidental corruption.

4×

Replay

Replays a recording at 0.25×, 0.5×, 1×, 2× or 4×.

2

Training simulator

A clearly labelled synthetic simulator with two channels, so it runs with no instrument attached.

x64

Windows desktop

Fully offline, on current Windows, as a 64-bit desktop app.
