Choosing the Right Fluke Signal Generator
Signal Type & Network Activity
The most crucial aspect when selecting a Fluke signal generator is understanding what cabling you’ll be working with and whether the network is active (powered on and transmitting data) or inactive. Some generators, like the Fluke IntelliTone Pro200, excel at identifying cables on active networks using digital signals (IntelliTone). This is invaluable for tracing wires without disrupting service. Others, such as the Fluke Pro3000 series, are designed primarily for inactive networks, using analog “SmartTone” technology. Using a digital signal generator on an active network is a significant benefit as it won’t interrupt the network’s operation. Conversely, if you primarily work with unpowered cabling, an analog generator is perfectly sufficient and often more cost-effective.
Range & Loudness
Consider the distances you’ll need to trace. Fluke Pro3000 models boast a range of up to 16 kilometers (10 miles) in most cables. This is essential for long cable runs in larger buildings or outdoor installations. However, range is useless if you can’t hear the tone. Look for generators with a loud speaker, especially if you work in noisy environments. Some models, like the Pro3000, include a 3.5mm headphone jack for even clearer audio isolation. A louder and clearer tone speeds up troubleshooting dramatically.
Cable Compatibility
Fluke signal generators support various cable types. The IntelliTone Pro200 is versatile, handling RJ45, RJ11, coaxial, and even bare wire (with appropriate adapters). The Pro3000 series focuses more on standard telephone and data cabling. If you need to work with a broad range of cable types, the Pro200 is the better choice. Check the specifications to ensure the generator supports the specific cabling you encounter most often.
Other features to consider:
- Tone Cadences: Multiple tones (like the 5 distinct tones in the Pro3000) allow you to easily identify individual wire pairs.
- Continuity Testing: Built-in continuity testing helps verify connections and identify breaks in the cable.
- Polarity Indication: LEDs indicating polarity are helpful for telephone wiring.
- Probe Inclusion: Some kits, like the Fluke Pro3000 Tone Generator and Probe Kit, include a probe, saving you the cost of purchasing one separately.
