You can change the frequencies in the correction table any way you like, up to any frequency?
? ?The tinySA Ultra is a great platform for experimentation as Erik allows the user access to the correction tables to improve its measurement level and frequency if the user has the prerequisite equipment and technical skill to do so.
? ?Erik is pretty much limited to 6GHz in his home lab, but Kurt Poulsen has a microwave set-up that is to die for and lent his time and expertise in developing the correction tables that are used in the production tinySA Ultra.
? My guess is that ham operators and electronic enthusiasts will see the potential in the tinySA Ultra and articles will start appearing that extend the capability of the tinySA Ultra to 12GHz and above.? The software is an area where a guru could definitely fill a void and build a multi-platform application, such as nanoVNA-Saver, for the tinySA Ultra. Erik has done a fine job modifying Cathy's nanoVNA-App program for the tinySA, but his real expertise is hardware and firmware.? That is the main reason tinySA-App is not as robust as the hardware.
