Features wanted for NanoVNASharp software

dk1vi All Messages By This Member #802 There are several features missing in current version: * Two permanent markers. There is only one marker displayed when hovering with mouse over graph. Not so easy to make a screen shot and still displaying marker value. * With two markers a delta marker funktion would be fine. * Sometimes the plots are rather noisy, so an averaging funktion would help.

And j+/-? :D toggle quoted message Show quoted text On Wed, 7 Aug 2019 at 15:10, dk1vi <dk1vi@...> wrote: There are several features missing in current version: * Two permanent markers.

Mike Brown All Messages By This Member #814 TDR. Other VNAs seem to have the feature. It would really help me with an iffy feeder I have running down the garden. toggle quoted message Show quoted text On Wed, 7 Aug 2019, 16:34 SPACE OPQA, <spaceopqa@...> wrote: What about coax cable length calculation?

Larry Rothman All Messages By This Member #816 You read my mind, Mike - I second the TDR function! Maybe the next version of the NanoVNA could also have a broadband noise source to act as a pseudo 'tracking generator' so we can do additional swept measurements? Just a thought.

F4WCV All Messages By This Member #822 Yes this will be good but most software assumes lossless cables so that? you can deduce the antenna Z from measurements from the shack end. The equations are there for the lossy cable cases but I don't? know any good software that can do that. Why?Sent from my Samsung Galaxy smartphone. toggle quoted message Show quoted text -------- Original message --------From: SPACE OPQA <spaceopqa@...> Date: 07/08/2019 18:54 (GMT+01:00) To: [email protected] Subject: Re: [nanovna-users] Features wanted for NanoVNASharp software Knowledge: also second the TDR :DOn Wed, 7 Aug 2019 at 17:35, Larry Rothman <ac293@...> wrote:> You read my mind, Mike - I second the TDR function!>> Maybe the next version of the NanoVNA could also have a broadband noise> source to act as a pseudo 'tracking generator' so we can do additional> swept measurements?>> Just a thought.>> Larry>> On Wed, Aug? 7, 2019 at 11:43 AM, Mike Brown wrote:> >> > TDR.
