Where should I upload the excel files to see the graphs as you showed? Thanks Avi --- End quote --- First post of this thread contains the files for download. Program does not need installation, running the executable is all that is required. |

Hi Great tool. Been trying a couple of components out, works fine. But it has problems with range due to the fixed reference resistor Have you considered if one added a USB controlled relay board to switch in different reference resistors over the range? Regards Klaus |
| _Wim_:
Considered, yes. But because I did not need this often, never implemented that. Also, it would then require others users to make the same hardware, which I consider a disadvantage also. It has been a long time since I even looked at this. As with many of my projects, at some point other interesting subject takes over before a project is really finished (I intended to allow for some calibration routines also, but never got around doing that). Currently no further development is planned, but maybe someday. All source code is available however, so feel free to add or modify as much as you want. |

Hi Wim, I'm using your excellent FRA Imp Viewer quite a bit. I still have a wish high on my list. When starting the program, the value of the series resistor has to be specified. However there are also probe tips attached to both sided of this resistor. The A channel side plays no role, but the probe's capacity on the B channel becomes part of the network and interferes with the measurement. That's why I always have to go to LTSpice trying to simulate a circuit giving the same characteristics including the capacity of the probe tip, to finally remove this capacity and get the real data for the DUT. You can imagine that that's quite a job. So it would be great if your program not only asked for the series resistor, but also for the capacity of the Channel B probe. Kindest regards, Hans |

Kindest regards, Hans --- End quote --- Hi Hans, To do something useful with the input capacitance, I would also need the calibration calculations (which are currently not included in the current version of the software, I never got around doing that). This would require a major update, which is currently not planned. Source code is however available, and visual studio can be downloaded for free. So it should be feasible to implement this change yourselves. If you have questions about parts of the source code, you can post them here, I will try to help you further, but for the moment, I will not be making any big changes myself. Best Regards, Wim |
