SGA3 Signal Generator

The SGA3 is a 33kHz Signal Generator designed for use alongside the CXL3 or DXL3 Cable Avoidance Tools to optimise performance and enable the detection of more buried utilities.

The C.Scope SGA3 is an affordable Signal Generator designed for use alongside a CXL3 or DXL3 Cable Avoidance Tool to make the task of cable avoidance far more effective. The C.Scope SGA3 will optimise the performance of the Cable Avoidance Tool enabling operators to locate more buried utilities including street lighting cables.

A C.Scope SGA3 Signal Generator is a vital accompaniment to a C.Scope CXL3 and DXL3 Cable Avoidance Tool and significantly increases the number of buried services that can be detected and reduce the day-to-day risk of cable strikes.

TWO SIGNAL APPLICATION TECHNIQUES
The 33kHz SGA3 Signal Generator can energise a buried metal pipe or cable either by ‘direct connection’ to the target pipe or cable or the simpler ‘induction’ method from above ground.

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 SGA3 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 SGA3s twin wall construction is robust and durable. It also provides IP65 standard protection against dust and water ingress.

ACCESSORY TRAY
The SGA3 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.
