FNIRSI 3 in 1 Oscilloscope 2 Channel Multimeter Signal Generator 2MHz Bandwidth 250 MS/s Sample Rate

水晶振動子の動作確認用に使いましたが正確に発信周波数をとらえています。

I bought this to set up my audio equipment in my car and so far I’m more than please with the results, after playing around with and seeing what I can do with it I’m hoping that I can inject a 40Hz signal and take a voltage reading at the same time I’m just not sure this meter will do just that but if it doesn’t I do have another voltmeter to get that measurement. We will see as time goes by and I play around with it to see what this thing will do. Of course I’ll give an update if after time it does more than expected or starts to disappoint. But either way I believe for what I know it can do at this point it’s well worth the money just having a handheld oscilloscope and voltmeter combined.
