Repair with Oscilloscope

[Rodemi]

Hi guys, has anyone used an oscilloscope to service a hash board?
A friend recommended to me that use the oscilloscope to maintain the hash board. I was wondering what model of oscilloscope would be easier to use and more practical?

Can someone recommend an oscilloscope with experience? Thanks!

I think a digital multimeter (DMM) would be more useful as a first tool for servicing a hash board. A cheap DMM will probably work alright, just make sure to get some high quality, long tip probes.

You're right. Multimeter is useful and handy for most hashboard repairs. But on the hashboard of the Innosilicon ASIC miner, there are some signals whose voltage cannot be detected by multimeter. If use a multimeter, the detection result will usually show 0. That's why I asked about the oscilloscope.
