[QUOTE="vma, post: 995631, member: 256592"] Hi, Right now I don't have time to check out the datalogger issue, but I just uploaded a small video showing my HD Touch, so you guys get an idea of the spectrum refresh rate. Please read the descriptions of the video, too, for further information. [MEDIA=youtube]L4Y2bXNMbpY[/MEDIA] The spectrum can be considered real-time, it is actually pretty fast, compared to other field meters in this range. In the end of the video, I am disconnecting/connecting the F-cable. This is to show two things: [LIST=1] [*]How fast the spectrum is rendered [*]How quickly the Astra 19.2E satellite is recognized [/LIST] When evaluating the refresh speed of a spectrum analyser, never just trust the real-time spectrum, while it is being fully rendered! This will NOT give hints on how fast the spectrum is. The best is to always disconnect/connect the signal. In the past I have come across Chinese meters (low cost ones), where between sweeps they actually played an animation on the spectrum, to make it look more "real-time"! Regards, vma [/QUOTE]
