Test Cells
Emissions
-
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 \re calibrated according to the methodology of IEC61000-4-20, thus affording compliant testing to IEC61000-4-3 and pre-compliance testing for radiated emission testing.

Pre-Selectors for EMC test
Emissions
-
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.

EMI Filters & Adapters
Emissions
-
The commonality in this section is conducted noise. Noise is not just a consideration when complying with EMC legal requirements, its is also potentially damaging and/or cause of failure of product performance or communications, even if the noise level is below EMC standards limits.

Product
Power Meter (LSPM)
Immunity
-
The LSPM series of RF Power Meters from LUMILOOP provides fast, accurate, and versatile power measurement across a wide frequency range. Designed for high-resolution time-domain analysis, pulse characterisation, and seamless integration with EMC test systems, these meters are ideal for modern labs requiring reliable RF power monitoring across multiple channels and applications.

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.

Clean Power Sources
Harmonics & Flicker
-
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.

Antennas
Emissions
-
Laplace offers a Comprehensive range of antennas. These cover all the radiated emissions and immunity test requirements. All antennas are supplied with calibration and AF data.

Product
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.

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.

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.

Amplifier Systems
RF Amplifiers
-
Systems are complete. They plug into an outlet and are ready to go. Our standard systems are 3U, which is 5.25″ and 5U, 8.75″. Systems are available with or without IEEE-488, RS-232 and Ethernet connectivity. Amplifiers Systems are available in both Broadband and Band-Specific frequencies.

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.

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.

Servo And VFD Filters
-
Operation of PWM-driven motors – servo motors and variable frequency drives (VFD) – causes several problems in equipment, including damage to the motor’s bearings due to leakage current causing electrical discharge machining (EDM) and damage to motor’s insulation. PWM motors also are a major source of EMI in equipment. These motor drive systems use pulsed power to drive the motors. As we are aware, the sharp edges of the pulses inevitably include high frequency components which can couple or radiate as noise to other parts of your system and cause unreliability, communication/control problems and EMC compliance issues.
