Amplified Probe
(Detects magnetic field and generates an audible tone)
Amplified Probe Antenna
Cable under test
Magnet Field around Cable (caused by Tone generator )
Tone Generator The probe will amplify all signals detected on cable including voice conversation, noise, data etc. This may cause the generated tone not to be heard.
INFINITY CABLING FLUKE Intellitone Tone Generator Operation
Amplified Probe Detects data word and turns on green Sync light. As the probe gets physically closer to cable being searched for an audio tone is generated and signal strength lights turn on.
