优点
EFT 500M4 - 高于标准要求的电快速瞬变脉ξ 冲群测试设备
The wide ranges offered to adjust the spike frequency and the burst duration are well-known for many years. Of course, the EFT 500M4 meets the latest waveform requirements into load at the coaxial 50ohm output as well as at the EUT port in common mode operation unlike other generators. The EFT 500M4 is for sure a fully compliant EFT/Burst tester.
Different models of the standalone EFT 500M4 are avialable. It can be ordered with a built-in single phase coupler as well as with a built-in three-phase coupler for rated EUT currents up to 50A.
The EFT 500M4 can also be integrated in a complete test system in combination with other generators of the EM TEST 500 series and operate via a common coupling/decoupling network being equipped with the corresponding control interface.
优点
Easy to operate
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.
软件
iec.control - Software for control and documentation
Outstanding user convenience, clearly structured windows and operation features and the EM TEST standards library along with the flexibility to generate user specific test sequences very easily are the main features of the iec.control software. The software is automatically configured according to the connected EM TEST generators. Extensive reporting capabilities help the user to create test reports that meet international requirements.
iec.control is supported by Windows 95/98, Windows ME, Windows NT, Windows 2000, Windows XP and Windows-Vista. Remote control is achieved either via RS232 or GPIB. The iec.control supports a wide range of GPIB cards of National Instruments.
附属设备
CNI 503 - 3phase coupling/decoupling networks for burst and surge
EM TEST offers a range of fully automated 3-phase coupling/decoupling networks for burst and surge to extend the test capability for three-phase DUTs. The networks have a rated current of up to 100A.
附件
HFK - Capacitive coupling clamp
The HFK is a fully compliant capacitive coupling clamp as per specification of IEC 61000-4-4.
ITP - Immunity Test Probes
ITP is a tool being used for development test. It consists of a variety of electrical field probes. The probes allow to locate weak points within a system or on a PCB. The burst pulse is used to generate the disturbance signal.
CA EFT kit - Verification kit for EFT/burst pulses
As per IEC 61000-4-4 Ed.2:2004 the characteristic of the burst generator needs to be verified with two different loads, 50ohm and 1,000ohm. EM TEST offers a calibration kit consisting of the two loads and an adapter to verify the pulses at the EUT output.
