Resonance Scan — Vibration Frequency & Mount Analysis

Identify vibration problems at a mounting point with your phone. Resonance Scan is useful for checking engine-bay vibration, cabin resonance, bracket flex, or whether a change in damping or mounting actually reduced the dominant vibration.

Best for

• mechanics and tuners comparing vibration before and after hardware changes
• users checking cabin or mount resonance at idle or steady speed
• anyone who needs a quick vibration comparison without extra test hardware

When to use this

Use Resonance Scan when you want to find the strongest repeating vibration, compare how strong it is, and see which axis is carrying it.

When not to use this

Do not use Resonance Scan when you mainly want an overall route or mount quality score across a complete run. For that, use Motion Quality .

What you get

• a live scan focused on dominant vibration behavior
• a saved scan with notes and optional setup photos
• comparison across repeated setups or operating conditions
• a report you can share after labeling the scans

FAQ

Can I use this to test a dashcam or phone mount?

Yes, if the question is specifically about vibration behavior or dominant resonance. If the question is overall recording smoothness, Camera Rig is usually the better first tool.

Can I use this on a bench, shelf, or 3D printer table?

Yes. Resonance Scan is useful anywhere you want to compare repeated vibration response, not only in vehicles.

This page covers both the mode and the central area because they use the same live scan panel and the same settings surface.

Mode

Open MENU > Modes > Engineering > Resonance Scan.

Use this mode when you want to inspect how a cabin, structure, engine area, or mounting point behaves under vibration.

Central area

You can also install Resonance Scan directly as the main central area: open the main panel menu, choose Pick what to show here, then in Screen area options > Engineering choose Resonance Scan.

The main readings tell you where the strongest recurring vibration energy sits, how strong it is, and which axis is carrying the strongest response.

Settings

Resonance Scan has a compact settings surface focused on session flow.

Max session duration controls how long the scan may run before it auto-stops and auto-saves.

Show saved scan details prompt decides whether the app should immediately ask for saved-scan details after the run is written. Keeping this on usually makes later review easier because the run can be labeled while the context is still fresh.

The session flow itself is also worth spelling out:

• START begins the scan after any optional setup photos are added
• STOP always opens the save or discard flow
• if the duration limit is reached, the scan stops and auto-saves
• interrupted scans are discarded, so long background interruptions should be avoided unless the scan is already saved

If you keep the saved-scan details prompt on, the app can ask for:

• test label
• mounting location
• operating condition
• note

Those details can also be edited later from the saved-scan review screen, so turning the prompt off does not lose that ability. It only moves the metadata work to later.

Good first setup

• keep the saved-scan details prompt on
• use a duration that matches the test you are running
• keep the mount fixed if you plan to compare scans later

How it differs from Motion Quality

Resonance Scan focuses on vibration characteristics. Motion Quality focuses on overall rig stability and user-facing performance comparison across complete runs.
