Hello! please tell me if there is a program for the Fluke-196B oscilloscope in which you can view the saved waveforms, for example, I took a freeze frame and I want to see it better, how can I transfer the picture to my computer? maybe someone has such a program, and I can download, thanks. Let me ask one more question, about the power adapter, everything works fine, there is a charge, but I noticed such a thing, when the power adapter is connected, there is some noise on the screen, if the power adapter is turned off, the noise disappears, what could be the reason? Not a great video when I connect the power adapter and when I turn it off. Do not pay attention to the flickering of the screen, this is how the camera transmits the picture. I don’t know how to upload a video here, I uploaded a video to another resource, you can watch the video by clicking the link. https://www.veed.io/view/057587d6-033f-44f3-9de5-f79fc90db25c |

Check out ScopeGrab32 (free / open source). Note that ScopeGrab32 uses screenshots - not actual waveform data. So you can't perform measurements or zoom in on your computer. You can enlarge the picture but it will not reveal more detail. Alternatively you can take a look at Sigrok (free / open source). I have never used a ScopeMeter with Sigrok but the 199B is on the list of supported hardware so I see no reason why the 196B wouldn't work. If you want more features, you'll need FlukeView for ScopeMeter Test Tools. Sadly this is not freeware. As for the noise when the power supply is connected, I noticed that you use a switched-mode power supply. I wouldn't be surprised if the noise came from that. The original Fluke BC190 power supply uses a transformer. I'm not seeing much of a difference on a 196C with or without the BC190 plugged in. PS: The voltage of your power supply is on the low side. The original BC190 outputs 17.8V / 840 mA (21 V without load). |

If I could look inside the original adapter and see what's in there, I would build one for myself. |

There is one question, is there a replacement for the 80TK thermocouple, since the native one costs crazy money. |

Hi, Check out the links for answers to your questions. https://www.eevblog.com/forum/repair/fluke-199225c-repair-blown-part-id/msg3957929/#msg3957929 ---------- https://sigrok.org/wiki/Fluke_ScopeMeter_199B https://scopegrab32.sourceforge.net/ https://scopegrab32.sourceforge.net/Fluke-RS232-reference.pdf You will need a PM9080 or OC4USB cable. Or connect directly to the scopemeter's IR transceiver via RS232 (MAX3232 TTL !) if you're confident in their actions. |
