Let me get one eye open simultaneously first, cold, half a pot of yesterdays coffee hasn't kicked in yet. Usually takes 2 to 3 cups to get me started right.
I'm also well pleased that I'm not being chastised for winders here, thank you very much for that. I bought this machine to serve as the web browser/administrator for a stemlab "redpitaya" because its one of the only bits of test gear I could find that can measure the impedance and reactance of a radio stations antenna tower and draw whats called a smith chart showing how that antenna is tuned. They all have a matching network at the base of the tower, and as other gear gets hung on the tower, it goes out of tune. The make has both windows code and linux code but the linux code doesn't work, something wrong in the comm protocol. Its taken me 3 weeks to convince the maker that his web page serving up this stuff is broken because it feeds a linux user following those directions, a windows .exe, which of course does run on linux. Backing up one directory I found the linux code kit, buckets smaller than the windows .exe, an all written in python3. I've apt-get installed all the linux stuff, python3 wrapped around matplotlib. It opens its own window when run, and draws the basic chart on-screen, but its missing the right hand column of buttons and isn't talking to the redpitaya. Its actually an stm32 running ubuntu in a cig pack case, and the rf bridge in a similar case. But the web server seems disconnected from the app even though the ap is running on another workspace of the linux box running ff and accessing it. Take a look at: <https://redpitaya.readthedocs.io/en/latest/appsFeatures/apps-featured/vna/appVNA.html> scrolling all the way to the bottom, you'll see a chart of a moderately well tuned antenna. Still isn't 100% centered on frequency, but a transmitter feeding it wouldn't be getting more than 1 or 2% of power reflected back to it. The tower I'll tune first is reflecting a good 20% back at the transmitter, making it run hot. The transmitter maker has sold the owner a handfull of big toroid cores to install on the feedline where it leaves the transmitter, but the ferrites have a "curie" temperature that can be below the boiling point of water in some formulations, that causes a loss of magnetic properties and makes the toroid run hot, hot enough he's shattered 2 of them like hitting glass with a hammer. At about $110 a core so busted. All that will go away if the antenna is "properly tuned", and this is the gear that can tell me which way to move coil clips and what have you to do this to achieve a chart, hopefully even better than the one at the bottom of the above page. That center dot should be closer to the horizontal centerline than it is. Ideally the center dots should be even closer to the 50 ohm mark at the center. This of course changes with the weather, phase of the moon and which side of your mouth you've got a chaw of Kentucky Twist parked in. :) All this is a dying art because the engineers that did do this tuning have largely died of old age. And with the General Radio gear of the day, would have to spend hours in the middle of the night logging data, and hours the next day drawing a chart from that data, before they could make an adjustment, repeat each night and day till it was close enough for the girls he went with, something this device can do in ten or less minutes per adjustment/measure cycle. My biggest problem will be in getting from the sma connector marked DUT for Device Under Test, on the bridge to the point on the matching network where the feed line from the transmitter is bolted into it. Those connections will need to be as short is possible. Thats what this is all about. A ticket to participate in the show will cost maybe $1100.
