Line Impedance Stablisation Networks (LISN)
Emissions
-
All commercial LISNs include an artificial hand connection and a transient limiter. This adds a 30dB insertion loss. A 30dB pre-amplifier is included which can be connected in the RF output feed to return the insertion loss to 0dB. All bar the heavy current LISNs are constructed in a flanged aluminium enclosure that can be bolted directly down to a ground plane (as required by standards). The underside of the enclosure is left unpainted to ensure good conductivity with the plane. The 16A and military/automotive LISNs have an RF output for each line, thus allowing parallel measurements of the emissions. This facilitates measurement of common mode and differential mode components of the emissions if required.

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.

Emissions Reference Source (ERS)
Emissions
-
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.

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.

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.

CDNs
Immunity
-
Laplace supply a wide range of CDNs that are fully compliant to IEC61000-4-6. 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.

DC Filters
-
This DC filter provides substantial noise reduction on DC power lines of up to 50V 9A. Filter provides noise suppression in both directions protecting your DC lines from noise generating by a particular piece of equipment or protecting your sensitive equipment from noise coming from DC power supply or other loads. DC filter provides noise suppression for both power lines – positive and negative, plus common-mode noise vs. ground. Filter uses plug-in terminal block for connections and mounting flanges for easy installation. Its rugged construction makes it easy to fit in many industrial tools.

Synthesisers
Immunity
-
The Laplace Synthesisers cover both conducted and radiated RF immunity test requirements. The frequency coverage extends from 100KHz to 500MHz for conducted tests (RFIC-4-6) and 30MHz – 6GHz for radiated tests (RF3000/RF6000). 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.

Test Cells
Immunity
-
LaplaCells provide a facility for the rapid and efficient testing of the EMC compliance of products. These cells offer a calibrated and screened environment in which radiated emissions can be measured and immunity to RF radiation can be tested. They exceed the requirements of IEC61000-4-20, thus affording compliant testing to IEC61000-4-3 and pre-compliance testing for radiated emission testing. The Cells are a modified form of GTEM cell, using a balanced dual septum design which maximises EUT volume for a given external size of cell, and dramatically improves field linearity. The EUT volume is fully lined in structural polycarbonate capable of supporting heavy products and access is via a large, full height door at the end of the cell. Adjacent to the door is the I/O filter compartment which can be customised to suit the users requirements. USB, RS232, Parallel, Ethernet, co-ax and other product specific filters can be added at time of ordering.

EMC Analyser
Emissions
-
Apart from the maximum frequency, these analysers are identical. Both analysers are available with a band A option to cover the range 9KHz-150KHz. They offer the ability to perform pre-compliance testing and compliance measurements. If measuring conducted emissions, use of a pre-selector is recommended owing to the impulsive nature of conducted signals.These analysers are supplied complete with PC software, fully compatible with Windows versions from XP to Win11.
