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.

3GHz EMC emissions Analyser
SA3000
The SA3000 is a powerful, fully featured, EMC analyser. It will measure both conducted and radiated emissions according to the international EMC standards. It enables the user to assess the EMC compliance of products quickly and with good integrity.

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.

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.

Ancillaries.. Conducted
The ease and effectiveness of conducted emission measurements can be enhanced by the use of appropriate filters. In particular, broadband noise below the frequencies of interest can cause limiting (compression) in spectrum analysers, distorting the measurements.

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.

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.

1GHz EMC Emissions Analyser
SA1002
The SA1002 provides a high performance capability to measure the EMC compliance of your products. It covers the conducted emission and radiated emission bands to 1GHz, as required by most EMC standards. The included software is Windows compatible and simple to use. This powerful system automatically sets the analyser parameters to suit the test to be performed. Standard limits are available from simple pull-down menu. Results can be directly compared against these limits for easy checks on compliance status.

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.

Ultra-Compact Immunity Tester
AXOS5
The AXOS5 is an ultra-compact immunity tester that performs all the most commonly used transient immunity tests, including Surge, EFT, Dips/Interrupts and AC/Surge Magnetic Field. The simplified user interface provides quick selection of tests and test levels, and even lets you change test parameters “on the fly” while running a test.The actual EUT power mains voltage and current are indicated in the display. Using the Electronic-Fuse function, the user can set an upper limit for EUT power mains current. This feature is useful to protect the EUT from unnecessary damage.Whether you test to the IEC 61000 series “CE Mark” standards, the IEC 60601 Medical Device standards, or any number of telecom and product specific standards, the AXOS5 tester is your one stop test station for everything from precompliance to full compliance to product development testing.A wide range of cost-efficient Coupling / Decoupling Networks for symmetrical and asymmetrical data- and signal-lines is available as an option.

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.
