Detailed Product Description: | What brand of Zhengzhou oscilloscope widest range? Daquan] [oscilloscope Tel :0371-55676313 QQ: 2417674438 Company Profile Zhengzhou Megumi Instrument Co., Ltd., established in 2002, is specialized in domestic and imported high-quality electronic equipment, instrument sales and service agents. The reason why we named "Megumi" because "beauty" in Henan has "Heart, just right, OK" means. "Megumi" is to provide you with the economic benefits, performance excellence satisfying instrument. Instruments operated mainly divided into: electronic measuring instruments, electrical instruments, electrical equipment, environmental testing equipment, nondestructive testing equipment, safety testing instruments. Its widely used in power industry, universities and research institutions, electronic products manufacturing enterprises, communications industry, radio and television, aerospace, petrochemical, railway departments. Companies strong, talented, able to efficiently complete instrumentation engineering product support and maintenance. Principal activities include: digital oscilloscopes, oscilloscope, signal generator, Sweep, spectrum analyzers, field strength meter, metal detectors, AC-DC power supply, bridge, pressure meter, earth resistance tester, Leakage current tester, insulation resistance tester, voltage tester, electrical tester, transformer tester, power meter, thermometer, infrared thermometer, noise meter, sound level meter, anemometer, a variety of harmful gas detector, water quality tester, hardness tester, vibration meter, coating thickness gauge, ultrasonic thickness gauge, gauge / micro-pressure gauge, flaw detector, roughness and so on. Over the years, in support of the community and the tireless efforts of all staff, we have established in the field of equipment sales high visibility and credibility, now has a perfect market system, marketing management system and customer service system. Our aim is dedicated test and measurement technology, communication and advocacy, with sincere service to help users improve work efficiency and capacity, and through active struggle and the pursuit of their own development and create opportunities for profit and power. Horizontal (X-axis) direction amplification circuit as a CRT horizontal deflection sensitivity is very low, so the access to the CRT horizontal deflection plate voltage (ramp voltage or other voltage) is first amplified through level after amplification circuit, coupled to the horizontal deflection plates of CRT, the horizontal direction to obtain a pattern of appropriate size. Scanning and synchronization circuit generates a sawtooth voltage scanning circuit. The frequency of the sawtooth voltage can be continuously adjustable within a certain range. Sawtooth voltage is the role of the electron beam emitted CRT cathode formed on the phosphor screen periodic, time proportional to the horizontal displacement, which form the time basis. Thus, in order to increase the signal in the vertical direction by the time variation waveform displayed on the screen. Power supply circuit power supply circuit: supply vertical and horizontal amplifier circuit, as well as scanning and synchronization circuit and control circuit CRT required negative pressure, the filament voltage. Oscilloscope schematic functional block diagram of the visible, the signal voltage is applied to the Y-axis input of the oscilloscope, the vertical zoom circuit applied to the vertical deflection plates of CRT. The horizontal deflection voltage of the CRT, although in most cases are used sawtooth voltage (for observing the waveform), but sometimes also use other applied voltage (used to measure the frequency, phase, etc.), so the level of amplification circuit input a horizontal signal selection switch to the oscilloscope in accordance with the need to use the internal sawtooth voltage, or use in the X axis plus the other input terminal voltage as the horizontal deflection voltage. |
