Handheld Digital Scopemeter Model WX4451 The WX4451 handheld digital scopemeter is a new-generation handheld instrument, designed to adapt scopemeter to application on the spot, adopts the update achievements of the modern test technology with the function of digital scopemeter and multimeter and has the characteristics of stiffness, security, lightness, portability, Chinese menu and so on. It has standard communication interface. Through the RS-232 interface, the PC software can communicate with computers, analyze data and archive the test outcomes. The WX4451 adopts the update circuit technology to decrease noise. Compared with current products in world market, it has higher test sensitivity and higher electromagnetic noise resistance. So it is the ideal instrument in national defense, scientific research, industry and education. Features: Auto set function, continuous fully automatic adjustment of amplitude range and time base. Waveforms and waveform parameters can be displayed on the screen at the same time. The user can choose parameters (Such as RMS, peak-to-peak, means, frequency, period, etc.) according to actual needs. With the 100Msa/s real time sampling rate in each channel and 20MHz bandwidth, it can reflect the waveform state quickly and factually and catch the fault impulse with the least breadth of 10ns. Saving and recalling function. It can save six groups waveform data and ten groups of parameter setups. High distinguishable crystal display. It can display the details of the waveform distinctly. With compact, convenient, full functional operating menu. Portable, light and small size, only 0.7kg per piece. Supplied with Ni-battery, It can be used under all kinds of environment conveniently.
