- Features & Specification
CScope SGV4 Signal Generator
The C.Scope SGV4 is a One Watt dual-frequency (33+131kHz) Signal Generator with in-built Data Logging can be used to enhance the capabilities of C.Scope Cable Avoidance Tools. It produces a signal with adjustable power up to one watt which can be used to energise underground metal pipes and cables via direct contact, wraparound or induction from above ground. The one-watt maximum power is ideal for energising longer, deeper pipes/cables which allows greater accuracy in cable locations.
The SGV4 produces a pulsed/continuous energising signal which is more accurate in crowded or noisy environments whilst an automatic daily self test helps ensure accuracy without the need for regular calibration.
As a datalogging signal generator, the C.Scope SGV4 saves all activity which can be recalled on the digital screen at any time. Activity data can be saved to a PC via a USB cable for analysis with the C.Scope PC Toolkit, which can be downloaded separately for free.

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 SGV4 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 SGV4 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 SGV4 means that deeper and less conducting pipes and cables can be effectively energised and then traced over ever longer distances.
It also features a FOUR position power level adjustment so the operator has total 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 SGV4 has a clear audible signal output to indicate when it is in operation.
A useful in-built audio mute control is also included.
To compliment and support in-built data logging on the Cable Avoidance Tools, the SGV4 Signal Generator also has full data logging capability. A years worth of data can be stored, in normal usage, on both the Locator and Signal Generator. This can be conveniently transferred at any time via a USB to a supervisors PC for analysis.
The SGV4 Signal Generators do not require periodic recalibration. A fully Automatic Daily Self Test (ADST) tests and confirms that they are functioning at their optimum level each day.
Automatic Daily Self Test (ADST)
The SGV4 Signal Generators perform a comprehensive Automatic Daily Self Test (ADST).
At the start of each day of use, a positive Automatic Daily Self Test result gives confirmation to the operator that the kit is working at the optimum level.
The result of this test is recorded and stored on memory within the products in-built data files and can be downloaded onto a PC at any time within the following 12 months*.
Pproduct Validation Certification
These test results can be used to produce a Product Validation Certificate using the C.Scope PC Toolkit. In addition, any results of the Self Test that have been carried out in the last twelve months* are available. The PC Toolkit can also be used to view and print a copy of the original factory Calibration Certificate.
C.Scope authorised Service Centres are also able to provide third-party Test and Calibration Certification should you require it to comply with client or internal requirements.
High Resolution Backlit Digital Display
The SGV4 has a large, clear and easy to read backlit LCD mounted behind a protective polycarbonate lens. The display indicates functions selected, power level, connection quality and battery condition. It also displays the Automatic Daily Self Test results.
Robust Durable Construction
The SGV4s twin wall construction is robust and durable. It also provides IP65 standard protection against dust and water ingress.
The SGV4 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.
Three Year Warranty
The SGV4 comes with a three year Warranty (conditions apply).
