old 5g spectrum analyzer, from before it was called 5g. communications in the mm wave spectrum arn't a new thing, they are just new to cell phone consumers. Not to be confused with 5g wifi, that refers to 5ghz. There is also a variant of what the cell phone companies are calling 5g which is in this range, it's referred to as 'sub-6.' This is microwave, but not the tiny 'millimeter wave' action of 28ghz where we are playing around. This older machine can handle that kind of high frequency, and non-consumer tech has existed taking advantage of this band since the 90s. That said, it's so exotic that we have to pay thousands to rent even this older unit. Periodically there is a chorus of clicking relays as it self calibrates and aligns filters inside. It's pretty magical. Holler if you want to see me boot it to hear and see this mysterious process.
