RF Synthesiser
The Laplace Synthesisers cover both conducted and radiated RF immunity test requirements. The frequency coverage extends from 100KHz to 230MHz for conducted tests and 30MHz - 6GHz for radiated tests. They are all controlled from the users PC via a USB link, and powerful Windows software is included to enable the user to control all the parameters of the test, to monitor the test in progress, and to view the results.

Source of Signals
CRS+
The CRS+ is a stable and calibrated source of signals which cover the 9KHz - 30MHz frequency range. The fundamental signal is a 15KHz comb and each harmonic is output as a narrowband peak of known amplitude. This signal is output on either the L and N lines, referenced to ground. A switch provides on/off and line selection.

Clean Power Source
AC1000A
The AC1000 achieves its unique price/performance ratio by actively adjusting the incoming mains waveform to produce a clean output. Other suppliers use convertor techniques to completely recreate the output from scratch. Our solution delivers an output which achieves the required THD with the minimum of hardware and expense. It includes the ability to switch the correction in or out so that the original waveform can be observed and measured if required. Overload and thermal protection systems are built-in and produce an audible warning if activated.

Near Field Probe Set
RF100
The RF100 probe set consists of a passive E field probe and H field probe, BNC adaptor and carry case. The output is via a BNC socket. These are general purpose probes which are ideal for use in conjunction with an EMC measuring system. They are sensitive to sources in close proximity, but are insensitive to background signals. This makes them ideal for the identification of emission frequencies in noisy environments... thus making measurements easier and quicker. The proximity requirement also enables sources to be located and the exit route identified.

Microrad RF Fieldmeter
Users can measure from static/almost static magnetic fields up to 6GHz utilising only two probes while remaining compliant with Directive 2013/35/EU. This solution is the NHT-3D meter plus 33P and 01E probes

LETIS
Power amplifiers that are universally used for radiated immunity testing either cover the range below 1GHz or the range above 1GHz. This means that if the test requirement extends both sides of this 1GHz point, the power amplifier needs to be changed over. Genrally, this involves three connections... The LETIS handles all these connections automatically. Each is switched via a high performance RF relay under the control of a USB interface. Software issued with the Laplace Synthesisers automatically detects the presence of a LETIS and handles the switching automatically.

CDNs
In addition to a range of 'conventional' CDNs, Laplace are unique in offering two other types. Both types are 'versatile' in that they are configurable, offering great flexibility in terms of the type of cable each model can be used with. This reduces the number of CDNs necessary to hold in stock. The final type is, in addition to being versatile, fitted with an output which monitors the RF level applied to the cable.

FaulTracker
FTR
The FTR Faultracker is a compact recording device which can be connected to up to 16 points in an electrical system. Any voltage from 12v to 240v can be connected. The FTR monitors the on/off status of each input. Any voltage above 6v is considered to be ON. An LED indicator on the front panel shows the status of each input. When set to logging, the FTR will log any and all 'events'. An event being the change of status of any input. Each event is logged strictly in the order it occurred with a date/time stamp. When logging is completed, the events can be stepped through one at a time so that cause/effect sequences can be analysed.

Emissions Reference Source
ERS
The ERS is a comb generator that radiates RF continuously every 2MHz over the range 30MHz - 1000MHz. Each 2MHz peak is precisely measured during the calibration process with the ERS orientated both vertically and horizontally. These measurements are correlated against a 3m OATS such that any fully implemented CISPR16 site, measuring at 3m and using height scanning, will read the same.

Ancillaries - Radiated
EMC emissions can be at very low signal levels and pre-amplifiers can help to improve S/N ratio. The low level of emission signals can make them difficult to identify in noisy environments. RF filters are designed to attenuate the major sources of noise, thus making the task of measurement easier.

Pre-Selectors for EMC test
These Pre-Selectors are high specification, switched band filters which track the scanning of the EMC Analyser. Control is via USB link from the Laplace EMCEngineer software supplied with SA1002 and SA3000 analysers. Installation and operation is completely automatic, and the filters will synchronise with the analyser scan without any operator intervention. A front panel switch allows manual operation if required.

Harmonics & Flicker Analyser
AC2000A
The Laplace Harmonics and Flicker analyser provides the user with a complete system for testing product compliance with IEC61000-3-2 and IEC61000-3-3. Quick and easy to use, the built-in screen provides a clear pass/fail indication of compliance status, plus a full listing of results for each harmonic, in either tabular of bargraph format. The instrument is properly configured to cope with fluctuating harmonics. The Flicker mode provides proper measurement of short term and long term parameters, using algorithms specified in IEC61000-4-15. In addition, inrush current measurements can be automated such that the product under test can be automatically cycled on/off with user entered time profiles.

ESD Test Simulator
ONYX16
The ONYX is a state of the art electrostatic discharge simulator available in 16kV or 30kV versions. It is the most ergonomic 30kV ESD gun without an additional base control unit that can be battery or mains operated. The easy to use touch screen, ergonomic design, modular RC units, multilingual interface, remote control software, built-in LED light and temperature & humidity display allows for trouble-free use of the ONYX in all types of test sites.
