[Test-Equipment] Landmark Instruments ?

[wolfbob]

Back when I actually did something rather than point, I 
found that the HP and later Tektronix spectrum analyzers 
were really a significant improvement over nothing and the 
Polarad stuff. The HP 8510 was such a powerful tool that I 
imagine everyone had it doing something even HP hadn't 
thought about (I made one in to an 3d imaging radar). The 
very high end frequency synthesizers capable of microsecond 
frequency switching and holding phase were also achievements 
that allowed a lot of data to be taken that could never be 
taken before. The FFT and family allowed not only MP3 but a 
raft of innovative measurements like nearfield antenna 
patterns and most all things in video/audio digital stuff 
and even cameras.
