A Cloner Sells Capability and Delivers Consistency
A multi-frequency cloner is bought for the idea that it can read and reproduce codes across many bands. What the installer actually experiences is narrower and more important: will it reproduce the same remote again next week, on the next unit, in the next city. Capability is a brochure feature; consistency is what determines whether the tool stays on the van.
What "Calibrated" Has to Mean
For a cloner to be genuinely calibrated, three things must hold simultaneously across the units it ships to different technicians:
- Frequency accuracy. Each band’s carrier must sit inside the tolerance the target protocol allows, because a receiver that rejects a 0.5% offset will reject a cloner output that a factory remote accepts.
- Timing accuracy. Pulse width and gap length are part of the protocol. A carrier at exactly the right frequency with the wrong pulse width still produces a signal the receiver ignores.
- Power consistency. Output power that varies unit to unit makes field behaviour unpredictable, because the technician learns that the tool sometimes needs to be held closer.
The Calibration Procedure That Works
| Parameter | Instrument | Frequency | Acceptance |
|---|---|---|---|
| Carrier frequency | Counter or spectrum analyser | Per unit, per band | Frequency offset against the band |
| Pulse width and gap | Logic analyser on the modulated output | Per unit, per band | Timing against the protocol |
| Output power | Spectrum analyser | Sampled per batch | Power tolerance across the band |
| Waveform signature | Capture and compare against the reference | Per unit | Exact protocol match |
Per-Unit Versus Per-Batch: Where the Cost Sits
Measuring every unit on every band is the rigorous answer, and it is expensive in test time. The pragmatic compromise is per-unit measurement on a representative band plus a sampled audit across the rest, with the sampling plan stated and auditable. What must never happen is a calibration record that was never taken and merely filed.
The failure this prevents is expensive and slow to detect: a batch that is 2 kHz off on the 315 MHz band still pairs with some receivers and not others, so the field reports it as “works sometimes” rather than “out of spec”, and the failure gets attributed to the customer’s vehicle rather than to the tool.
A calibration record that cannot be produced on request is not a record. Ask for it per serial number, not per batch.
Questions to Put to a Cloner Supplier
- Is the frequency tolerance stated per band in µA or in percentage, and is it measured or nominal?
- What is the output power tolerance across the band, and does it hold at the ends of the band as well as the centre?
- Can calibration data be retrieved by serial number for a unit you own?
- Does the firmware version get recorded against each unit, since a firmware update changes the behaviour of the same hardware?
