个人感觉20M的很多地方的波形都不可以测量啊

那就不要，，等研究透了再买不晚，

我认为不值
20M的，带宽太小了点

性能：

The Hitachi V-422 (R) [V-222] * is a portable-type, advanced-class oscilloscope with a bandwidth of? DC to 40 MHz[20 MHz] designed with the emphasis on operability and port-ability and has a following features.?
[ ] * : Specifications of V-222
(1) Wide bandwidth:The instrument has a bandwidth from DC to 40MHz[20 MHz.]
(2) High sensitivity:Sensitivity is 1 mV/div
(3) Large 6" screen:Employment of a large square CR1 makes waveformseasier to observe.
(4) Internal graticule:Employment of an internal graticule CRT permits wave-forms observation to be made without parallax error.
(5) DC OFFSET: Allows a proportionate observation of any part of an input waveform even when it is in a large amplitude.
(6) ALT MAG Allows simultaneous observation of? X1 and X10 sweeping waveforms.
(7) ALT TRIGEven an observation of two waveforms of different fre- quencies, the waveform of the each cannel is stably trig-gered.
(8) TV synchronization:Employment of a new TV sync separator circuit allows theinstrument to observe TV signals stably.
(9) Auto focusing:Focusing shift is automatically corrected.
