OneOfEleven, You probably noticed the following: 1. The VDD and BOOT pins are available as a last resort for a user that can't access DFU mode in the usual way. 2. No SanDisk pads are available, so

Thank you Herb. Am trying it with manual ref-level (-10dB) set, all appears OK now. The auto ref-level code might need some tweaking by the looks of it :) My heads full of NanoVNA code at the

OneOfEleven, Try setting LEVEL->REF LEVEL_>MANUAL.? Your video shows the reference level changing when the level shifting occur.? In rapidly changing signal environment,? manually setting the

A scan of the PCB with the covers removed.

The sudden jumps are always 10dB up/down.

Hi Erik I was wondering what you think might cause the base line to jump up and down like this. I'm using your latest firmware as of today, but it was the same with your previous firmware

Gary, What is your current application of the tinySA?? Knowing how the tinySA is being used by its users would probably help Erik to beef-up the Wiki in those relevant areas. - Herb

Thanks all for the clarification. Gary W9TD

I checked. On purpose I let the resolution filters overlap somewhat? so this helps the interpolation. There is no I/Q signal and FFT but 57 resolution filters ranging 2.4kHz to 600kHz and then a

That little bit of code I put here only really helps if the carrier of interest is somehow spread across 2 or 3 spot frequencies (bins in the FFT world). Otherwise it has little to no effect at

Line should be .. if (idx > 0 && idx < (sweep_points - 1))

You can get a better frequency estimate for a marker that is set to "Tracking the peak". I modified this bit with some extra code to estimate the actual carrier frequency .. ========= sa_core.c line

Herb, Thanks for the good explanation. Gary, Thanks for find the ACTUAL FREQUENCY was missing in the wiki. Its added now: https://tinysa.org/wiki/pmwiki.php?n=Main.SETTINGS2 I added the frequency

What does the menu item 'correct frequency' under the 'expert config' menu do? The frequency displayed by the marker is 159.861 MHz for an actual input frequency of 160 MHz. Under the same 'expert

Good suggestion

Thanks, Erik. ?No need to implement VBW - I can use the averaging functions. ?The only final comment is that if someone is coming in from a full-featured SA, they might wonder the same as I do.
