This short video shows a cool feature of the Tektronix 1401A Spectrum Analyzer Module that helped users find signal frequencies through a unique "marker" function. This function was the way to "mark" a particular frequency for further analysis or measurements, before the advent of more fully integrated spectrum analyzers with multiple markers were developed.
I'm so glad you and others are posting information like using this old 1401A. Not only does it teach others how such old equipment works but it also makes raw knowledge available to people like myself who would never have the chance to even be exposed to such knowledge. Keep up the great videos!

@toddrharrison Todd - thank you for the nice comments. I really enjoy the technology of these pieces of analog test equipment. Hmmm - maybe I'll do a video on my Grid Dip Meter...
