Nope... I just have a couple old Tektronics scopes.
You're just an old-fashioned guy, Roscoe.

Looking for someone who can reliably repair analog oscilloscopes. I have two that are now making different types of noises, though the display and functionality seem OK, and I think I have one more with other problems. DC area would be nice but I could ship. |

analog o-scopes are very cheap now, might not be worth repairing |

Yes, I was going to say that I bought a portable analogue 'scope in perfect working order for $65 on eBay. I see a few BK's and Tek's there right now for $100-150. On the other hand, a base model Picoscope USB scope is only $130. That's what I use most of the time now. The software is free and has plenty of automatic features. |

Definitely a little more money but some of the new digital scopes are within striking range pricewise and offer very important features. Here is a smaller brother of one I have that works great. First, the horizontal size of the display is larger which allows more cycles to be viewed. Second, a section of signal is stored so you can chose the parts before and after what is displayed initially to analyse. Third, the displays use color which is very helpful when overlaying traces. Fourth, the scopes perform measurements like voltage (RMS, peak, average) frequency, etc. Fifth, they are storage scopes. Sixth, there is a USB port that allows use of a flash drive to capture a jpg image of the trace for reference. Etc, etc, etc. If you would like to see it in action I could bring mine to one of the meetings. I believe Roscoe has a similar version under the Rigol brand. https://www.amazon.com/Siglent-Technolo ... 702&sr=8-1 |

I agree that the digital scope offers many valuable things - especially if we read the manual! - and it is possible we'll switch over. It does seem like getting a new one is the best option financially. I was hoping to avoid that out of principle, since we have these repairable things, but they'll probably have to wait for someone else to save them in the future. Thank you for the recommendations. |
