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.

Coupling Decoupling Network (CDNE)CDN
Emissions
-
CDNEs are based on the CDN as specified in IEC61000-4-6 (Conducted RF Immunity test). In this test, the CDN is used for the coupling of RF onto a cable. In principle, the CDN can be used in reverse, ie coupling any RF on the cable out to an analyser. In an earlier version of EN 55015, these CDNs were specified as suitable for measuring emissions. However, the current version of the standard specifies a CDNE which is essentially a CDN refined to deliver higher accuracy particularly at higher 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.

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

Product
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.

Electrostatic Discharge (ESD)
Immunity
-
The sudden, momentary flow of electric current between two objects with different electrical charges.

Product
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.

Power Amplifiers
Immunity
-
The RF power amplifier range from Laplace is specifically designed for EMC Immunity testing according to IEC61000-4-3 and IEC61000-4-6. These are compact units with characteristics matched to the requirements of IEC standards. These RF amplifiers utilize fully isolated linear MOSFET or advanced GaAs FET devices, which provide high gain, wide dynamic range and excellent third order intercepts. High efficiency and reliable operation are achieved by employing unique RF combining circuits, RF microstrip networks, sophisticated thermal design, custom machined housing and heavy duty components. The high power RF amplifiers undergo extensive burn-in prior to final test and inspection.

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.

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.

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.
