Cable SIGNAL GENERATOR
Signal Generator
Utility Cable Testing & Tracing Device for KSA & GCC Infrastructure Projects
How a Signal Generator Works
Signal generators work by creating an electric or electromagnetic signal that is under control and is passed through the intended utility. The following steps are most commonly involved in the process:
Connection to the Cable
First, the generator is connected to the utility cable that could be either active or inactive.
Signal Transmission
Then, the unit sends either a low-frequency or a high-frequency signal through the cable.
Detection
A compatible cable locator or receiver is used to find the signal above ground.
Tracing and Mapping
The operator moves the receiver along the way of the signal to find the cable route.
Fault Detection (Optional)
In this way by tracking the signal strength or continuity, it is possible to detect faults, breaks, or open circuits.
Types of Signal Generators
Signal generators are categorized based on application, frequency range, and functionality:
1. Passive Signal Generators
Detect signals from active lines without connecting to the utility.
Useful for tracing live power cables or telecom lines.
2. Active Signal Generators
Inject a controlled signal directly into the target utility.
Ideal for inactive cables, conduits, and fiber optic ducts with conductive tracers.
3. Multi-Frequency Generators
Provide variable frequencies to improve detection accuracy in dense utility corridors.
4. Battery-Operated / Portable Generators
Lightweight and portable for field use in construction, telecom, or municipal projects.

Connect to Utility
Direct connection clamps, an inductive clamp, or a tracer attachment can be used to connect the device to the utility.
Select Frequency
The frequency should be adjusted based on the type of utility, distance, and detection requirements.
Activate Signal
The wire shall be signaled by the signal generator, which is made to send signals through it.
Trace with the Receiving Unit
A suitable cable locator or receiver should be employed for the detection of the signal and the mapping of the route.
Analyze Faults (if needed)
Signal strength changes should be closely monitored to identify breaks, open circuits, or insulation damage.
Data Recording
GIS or utility management will record the location, depth, and fault info.
