Also, LTspice from Linear Technology (now part of Analog Devices) has been freely avaiable for a long time. There is a Yahoo group, LTspice, which provides excellent support and information. DaveD

Sean,Are you aware that the simulation software call MicroCap is now free? http://www.spectrum-soft.com/ Try simulation first to give you a rough idea of your component values, then prototype and

With respect to matching networks, have you seen W2AEW's Youtube channel? https://www.youtube.com/watch?v=IgeRHDI-ukc Also, do follow the link to W0QE's Youtube channel: SimSmith is very nice

Yes, I meant correction.You have a save menu after the correction button.. shouldn't be one. Correction is on or off.I still think reset should be at the top of the list and save after calibrate

I am aware of that, like I said, I'm new to RF, but I understand that without a non reactive part of impedance in the antenna, there's no power going into the antenna right? If the LC is at resonance,

Hi aa--something Cables length as such has basicly no influence. Consider the cable as part of the hardware system, they are calibrated away. The only effect is small potential phase variation if the

Thank you Erik, that explains it, an image.? So I just ignore the lower frequency of the two peaks.? And it's possible to calibrate the amplitude.? I will try the test of seeing the FM BC band with

I tried my nanovna as a spectrum analyzer and it is interesting.? Amplitude isn't calibrated.? I measured my signal generator and it shows me two responses fairly close together; I verified on my

Hi Larry - OK, I never dared press DFU and anyway added a slide switch for hard DFU, too often required for hangs.. OK, I see "CORRECTION", not "Calibration" Maybe raw data helps understanding impact

I wanted a printed chart that I can hang on my wall so I changed the color scheme. I hope there will be no objection to me sharing an ink-saving chart.

gin & pez @ arg; I am comforted that I seem to be approaching a conceptual understanding of your work. It has elevated my interest. I am responding to your question with an expanded definition that is

When you click the DFU menu button, you get the next menu with 2 items: Reset and Enter DFU and Cancel.? The full word:. Calibration is a switch that can be inverted text to show calibration is being

Since ohms are obviously not watts, please give us the formula that you are using for that conclusion.

Hi Larry - I totally agree and can rearrange that on the tree.. Actually, I calibrate pretty often, nearly every time before measurement, to consider everything except DUT as "ideal". Yes, but my CSS

Also, touch screen seems much less responsive than Gen Hu releases, and hung repeatedly (requiring power off/on) when trying to set START stimulus.. ... back to NanoVNA-H__900_ch_20191003.dfu

It eventually hung at power-on for me WITHOUT doing touchscreen calibration, fortunately after capturing mostly legible menu screens. Took this opportunity to exercise starbuck5250's DFU-from-Hex
