| Shopping for used scope to use as curve tracer |

| Electron123:
I'm thinking of buying a used scope to connect to a go/no-go breadboard curve tracer. I have a new digital one but, from what I've discovered and read, it can't be used as a curve tracer. So before I go shopping, can anyone give me tips on what I should look for to make sure a scope can work as a curve tracer? I plan to use it for trouble-shooting and don't need anything fancy, so I'll be looking for budget equipment. |

Assuming that you just need a workable XY display mode, most any old analog CRO would work. However, many or most DSOs would also work if you configure them properly. What scope do you have that won't work with your tracer? |

I currently have a Rigol DS1102. Most of the used scopes online don't come with probes. Will any set of basic, passive probes due? And are the barrel connectors all the same or do I need to get something model-specific? |

By "barrel" connections I'm assuming you mean BNC, those are standardized across almost all scopes save for some really exotic stuff. Lots of decent dirt cheap probes, the common P6100 can be had for about $20 a pair and work just fine. I do typically glue the X1/X10 switch to the X10 position though, I have no idea why almost all cheap probes are switchable. Not all scopes have XY mode so do confirm that is there before you buy something. Does your DS1102 not have XY mode? It's pretty crap on every DSO I've tried, but should be adequate for a curve tracer. |
