My Ultra has different labels on its ports #ultra

 

I just received an Ultra via R&L.? My HW version is V0.4.5.1.? I noticed that the ports on the left side are labeled differently from what I have seen in videos and images.? The top one is labeled "Cal" and the bottom one is labeled "RF."? I was expecting high and low ports.? Did the Ultra change or is this just labeling?

Ultra has always used CAL and RF as port names

Bill,

The Ultra is a complete circuit re-design and does not use high and low ports.? I

High and Low are from nanoVNA. ;-)
