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.

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.

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.

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.

Voltage Probes (Power Line Interference Probe)
Emissions
-
The Voltage Probe requirement is covered by our PLIP (Power Line Interference Probe). This fully meets the requirements of CISPR16, but has additional features: Fully galvanic isolation between input and output (>1kV), for the safety of operator and analyser. hrouded safety clips for attachment to the line to be measured. Filtered frequency response matched to Band A and B. Current limiting on the output. Visual indication of high voltage input

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.

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.

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.

RF Filters
-
RF Filters block unwanted frequencies when testing electronic devices for emissions during EMC testing. They attenuate unwanted frequencies and allow the desired signals through. The RF filters isolate the device under test from external RF noise, this increases the reliability and accuracy of the EMC testing by preventing out-of-band noise and harmonics.

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.

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.
