CWS 500N1- SERIES

The CWS 500N1 is the most compact single box test equipment for testing conducted rf immunity as per IEC 61000-4-6 and related standards. Apart from the 1kHz 80% AM signal the CWS 500N1 also generates a 2 Hz 80% AM signal to test medical appliances and a 1 Hz PM signal with 50% duty cycle required to test safety equipment like fire alarms. Equipped with a 1 GHz current monitor the CWS 500N1 can be used up to 1 GHz by means of an external amplifier.

EM TEST supplies a large range of CDNs, EM clamp and current injection clamps as well as the corresponding calibration accessories. Full compliant levelling can be run from the front panel of the CWS 500N1 storing the results in one of the 5 memories.

One single box replaces five dedicated items. Hence setting up for testing is much easier and faster, saves space, is much more reliable and you achieve a higher reproducibility of the test results.

The CWS 500N1 offers the best benefit-to-cost ratio. Calibration/levelling of the test set-up has never been easier; terminate the DUT port with the calibration adapter, connect this to the 150ohm-to-50ohm matching impedance and lead its output to the Cal Input. Start the calibration routine and you are done in a minute.

The signal generator delivers signals up to 300MHz for the internal amplifier while the frequency range can be extended for 9kHz to 1GHz using an external amplifier.
The powerful, top-performance built-in class A amplifier allows to test up to 30V using any kind of coupling/decoupling device (CDNs, EM clamps, current injection clamps). The built-in 1GHz current monitor offers the ability to control the injected current signal while using injection clamps.

The EM TEST specific Quick Start test routine complemented by pre-programmed Standard Test routines make the CWS 500N1 completely independent from operation by software. icd.control software extends the capabilities of the CWS 500N1 to a complete rf test system, e.g. performing enhanced calibrations (customised voltage level or frequency range) through the built-in power meter.

Front panel menu and function keys enable the user to program his test routines quickly and accurately. The cursor allows fast control of all test parameters of the programmed routine, thus test procedures are simplified and confidence is generated that every step is carried out correctly.

By means of the powerful icd.control remote and documentation software the CWS 500N1 is extended to become a complete rf test system. Offering a library of standard test routines tests can be performed as easy as ever possible. Calibration can be performed in selected frequency ranges, at any desired test level and with a resolution as accurate as 0.1% or with the minimum frequency step width available.

But icd.control would not be an extraordinary tool without its outstanding and unique capability to implement up to four different measuring devices. These measuring instruments can be used for any kind of data acquisition controlling the entire test procedure. DUT monitoring is easier then ever before. Even most complexe test routine can easily be programmed based on vector-defined test points.

Continuous wave simulation over 9 decades! The CWS 500N family not only covers the frequency range mostly required for industrial test applications based on IEC 61000-4-6 but EM TEST also offers dedicated solutions for the low frequency range as well as for BCI (Bulk Current Injection), TEM cell or Stripline applications in the automotive, aerospace and military area.

The CWS 500N4 is the state-of-the-art solution in a compact single-box design to test for immunity to conducted, common mode disturbances in the frequency range 0Hz (DC) to 150kHz. Such test requirements are specified in IEC 61000-4-16 and cover continuous mode testing as well as short term testing with DC, 16 2/3Hz, 50Hz and 60Hz with 4 test levels each plus a sweep mode from 15Hz to 150kHz.
