sample rate for use with antenna positioning and design
Posted: Wed Oct 29, 2014 12:03 pm
Hello,
In the setup you can change the Refresh Loop of default of 1000ms(1sec) but it still samples at 1 second.
Example: 250ms = .25 second so when changed in the setup it samples three .25 samples including the forth .25 which jumps the movement in the graph at 1 second. In short, 1,2,3 jump,1,2,3 jump etc. etc.
Is it possible to smooth out the sampling when selecting a lower rate in the settings?
Why I ask is not only do I use the graph for positioning an antenna, I also do antenna design form standard dipoles to high gain antennas. A smoother and fast sample rate makes things a bit easier when working with an antenna. I do have a HP 8569 spectrum analyzer, but that thing is a quite heavy and way too expensive to be carting out side to do any range and gain testing. My SDR receiver that I use with the laptop cuts off at roughly 1.5 GHz, great for other things, but not for WiFi.
I know that this program is not meant to be for the purpose I am using it for, but it is helpful for knowing what I am looking at besides a standard 2.4GHz signal source.
Cheers
Tom
