The links that Andy provided to inexpensive digital storage oscilloscopes were great. I was thinking of something like that. I should have provided the links. Even if you value your time as FREE, you'll save enough in wasted materials used trying to guess where the problem is and what might fix it to pay for an inexpensive digital storage oscilloscope, not to mention the cost of the products your customer scraps when an undiscovered noise glitch manifests itself while you're on your way home after guessing where to plant the ferrite magic beans. A friend would borrow me and my digital storage oscilloscope to solve his noise problems in industrial equipment he was building. Last week, he offered to give me his old Heathkit oscilloscope (the old CRT variety). He had just bought a PicoScope... a DSO module that uses a Windows notebook PC as the user interface. I declined on the old scope offer, because I didn't need it, but it would be sufficient to view noise on various CNC signals. I did a lot of troubleshooting with analog scopes before getting a DSO. Around here, analog scopes are often free to a good home. If the shipping wasn't way more expensive than the scope was worth, I'd mail it to you. Certainly you can get an oscilloscope of some sort. Maybe borrow one for this project? You're just guessing and flying blind without one, IMO. It's almost true to say that you can't fix what you can't see. If you fix it without seeing it, you guessed and got lucky. It's no way to integrate production equipment, IMO. I'll admit to doing some guessing and getting lucky in the past, but I never liked that process. I greatly prefer to know what I'm doing. I like seeing it with my own eyes. ------------------------------------------------------------------------------ Master SQL Server Development, Administration, T-SQL, SSAS, SSIS, SSRS and more.
