I own a Hantek DSO2C10 digital oscilloscope. The machine came with one probe, and that one needs to be replaced. I was able to find the appropriate replacement. However, Amazon doesn't have them in stock.

Suggested Replacement Probe

I can find them on Ebay. However, those would be shipped from China, and would take forever to arrive.

After doing some searching, I've learned that I can purchase a different brand, as long as the input capacitance and bandwidth freqencies are the same.

According to the specifications of the replacement probe, the input capacitance is supposed to range from 85pF to 115pF.

Probe Specifications

Digikey seems to sell some that have an input capacitance of 120pF. Is this close enough, or do I need to keep looking for something else?

What Digikey Offers

This may seem like a silly, simple question. However, I've never bought oscilloscope probes before, and would hate to buy something that isn't right.

Thanks for your time.

 

After looking at the actual datasheet, it shows that the input capacitance can range up to 120pF. This is different than what the specifications show, on the Digikey website; which is a hard value of 120pF. Because of this, I think this should work.

I would delete this thread. However, I don't know how.

 

That input capacitance value is the probe capacitance in the 1X mode.
It is only partially related to the oscilloscope input capacitance.

You need to know your oscilloscopes input capacitance and buy a probe that's rated for that.
It's this spec you are concerned about:
Compensation scope: 15pF-35pF
So, for example, to use that probe, the 'scope input capacitance should be within that value.

The Digikey one doesn't specify that.

Thanks. I reached out to Digikey, and have learned that this probe has a compensation range of 10-35pF.

I realize that the input capacitance, that I mentioned before, only relates to the probe for 1X. I was only concerned about that value, because it seemed to be the only corresponding value that didn't match that of the PP-150. The corresponding values, for the probe in 10X, match.

Thanks, again, for responding. Like I've said, I'm new to this, and haven't had to replace an oscilloscope probe before. At least, I now know, more about this.

The value is of interest for doing measurements with the probe, but it's not generally pertinent to selecting a probe.
