Exquisite design and manufacturing comply with CISPR 16 standards, and fully comply with CISPR 14-1 for discontinuous interference test (called "click") international standard specifications. Equipped with advanced EMI test software, multiple windows real-time display of measurement results and time domain analysis function, built-in pulse signal generator.

  DDA55 built-in PC (Windows 10 OS), combined with advanced software can quickly and accurately perform fully automatic click analysis. DDA55 is not only a GO/NO-GO tester, but also a multi-channel discontinuous interference analysis mode, which can provide real-time analysis of when, where and why the click occurred. This system is of great significance for solving such problems.

  DDA55 uses four parallel independent channels of fixed frequency (150kHz, 500kHz, 1.4MHz, 30MHz) radio frequency receiver, each test channel can perform "peak and quasi-peak" detection capabilities, fully in line with CISPR 16-1-1 standards Requirements, the quasi-peak detector is designed to be tested in accordance with the CISPR 14-1 standard, integrating the oscilloscope (time domain measurement) function, and the system also provides all, single and multiple interference pulse signal generators that meet the requirements of the CISPR16-1-1 standard. DDA55/VCCI option_According to the Japanese VCCI radiation standards, an optional 500kHz/550kHz fixed frequency radio frequency receiver module can be provided.

  The PC is connected with DDA55 through the LAN high-speed network port to realize automatic configuration test and output test result report, advanced software control analysis, and supports WINDOWS 10 operating system. All test parameter settings can be performed, fully complying with CISPR 14-1 standards or other standards. All DDA55 test messages can be displayed on the PC screen in real time, and each independent test channel can correspond to an individual measurement window.

  The DDA55 built-in pulse generator can provide four standard measurement frequencies (150kHz, 500 kHz, 1.4MHz, 30MHz) and two according to the requirements of CISPR 16-1-1 (T17) CISPR 16-1-1 (F.1) User-defined frequency to generate single and multiple time interference pulses in order to achieve the self-calibration function of the click analyzer.
