Re: Firmware font size - 2 versus 4 trace
There are two flash parts, one 96k and one 32k Assuming the 32k flash holds the data store (did not analyze yet), the 96kByte flash has maybe 1kByte left. (code + initialized data is in total 97440

Re: Firmware font size - 2 versus 4 trace
Erik, Thanks for confirming memory capacity is a factor in the font sizes. My progressive bifocals work fine with the smaller fonts, but I imagine it's just a matter of time before someone releases a

Re: Saver with Win7
Hi Rune, The group delay (GD) is obtained from the transmission phase, S21. The negated value of phase shift calculated as the small change in phase shift occurring with a small change in frequency.

Re: Saver with Win7
Thanks for the suggestion, Bryan. It sounds interesting. Do you know if/how group delay is determined from S-parameters? I'm not really an RF engineer, so I have had to figure out all these things

Re: Firmware font size - 2 versus 4 trace
Indeed, larger fonts need more memory. Prefer to spend memory on more useful features. Suggest to buy small reading glasses. I did..... Hugen does not have the large font size version on github (I can

Re: Firmware font size - 2 versus 4 trace
Erik, Is there enough firmware space on the uP for one more firmware on-screen option to display either 2 larger or 4 smaller traces? I think that would be a nice option to have. I know Hugen's
