示波器 VP-5520B 200MHz/双通道/双扫/九成新 体积: 31×15×40 cm 重量: 9 kg 厂家: 日本松下 现售: 5500元 简介: This wide-band portable oscilloscope, Model VP-5520A(B), which is compact and light in weight, is designed to cover use in a wide range of environmental conditions through full employment of transistors and ICs. The VP-5520A(B) has a vertical amplifier circuit which permits a dual-trace display in such a wide-band of from DC to 200 MHz. The sensitivity range is from 2 mV/DIV to 12. 5 V/DIV. and by connecting channels 1 and 2 in cascade it can be increased to a high vertical deflection factor of 400 μV/DIV. The trigger circuit operates stably in the entire frequency range of measurement and has an auto trigger facility. The sweep time is wide in range of from 2 nsec/DIV to 1.25 sec/DIV, and a delayed sweep feature of the trigger circuit increases measurement accuracy. The instrument can also serve as a precise X-Y oscilloscope or triple-trace oscilloscope with the third trace to view a trigger ** in the display.
