Here’s my Amber 4400 test set brought back to life. It’s a sweep function generator with sweep filter , dbm meter and plotter for displaying frequency and phase. Some capacitors one cmos 4066 chip and a bunch of contact cleaner.
There are many apps that do this today on a laptop but not much in 1976 so this was an answer. The guy that developed this in Canada also made the short lived Olive console. I’ll post some more info if anyone is interested. The scope is showing a 20 to 20khz plot with some markers. I should put this on an eq but it’s a flat sweep of a sine wave with a +\- 10db window.
