The C.Scope SGA4 is an affordable Signal Generator designed for use alongside a CXL4 or DXL4 Cable Avoidance Tool. It enables significantly more underground utilities to be detected including street lighting cables.

SIMULTANEOUS DUAL-FREQUENCY
The simultaneous dual-frequency 33kHz and 131kHz signal output of the Signal Generators is ideal for maximising the number of buried services that can be energised and then detected.

The SGA4 Signal Generator can apply the dual frequency signal without direct connection to buried services, using either a Signal Clamp or the simple induction method from ground level, providing a significant improvement in the detection of the smaller diameter or poorly earthed cables.

THREE SIGNAL APPLICATION TECHNIQUES
The SGA4 offers three alternative ways to apply a Signal Generator signal:

Direct Connection allows specific pipes or cables to be individually traced, identified and their depths measured. The use of Signal Clamps, Signal Injectors and Direct Connection leads make this mode the most effective method for pinpointing pipes and cables.

If it is difficult or inconvenient to use Direct Connection, then the Wraparound technique can be utilised to successfully energise a street or car park lighting cable.

Induction allows the Signal Generator to induce a detectable and traceable signal to previously unknown, undetected or inaccessible underground metal pipes or cables.

HIGH POWER SIGNAL
The fully adjustable One Watt Power Output of the SGA4 means that deeper and less conducting pipes and cables can be effectively energised and then traced over ever longer distances.

It also features a two position power levels so the operator has some control of how much power is in use and when.

PULSED/CONTINUOUS SIGNAL OUTPUT
A Pulsed or Continuous signal output allows operators to switch to the Pulsed Mode at the push of a button in high interference situations and keep on tracing. The SGA4 has a clear audible signal output to indicate when it is in operation.

A useful in-built audio mute control is also included.

ROBUST AND DURABLE CONSTRUCTION
 The SGA4s twin wall construction is robust and durable. It also provides IP65 standard protection against dust and water ingress.

ACCESSORY TRAY
 The SGA4 Signal Generator has a large detachable accessory tray as its base. It can house not only the standard accessories (Direct Connection Leads, Earth Stake, Connection Magnets, 10m Auxiliary Earth Lead) and the Instruction Manual but also many of the optional extras such as Signal Clamps, Sondes and Signal Injectors.
