Hi Joerg,
Sorry for the delay in replying; I've been away in Europe for a few
days.
It's the same HP 8754A analyser that appears in another thread of mine
hereabouts (4-1300Mhz). Probably rather too old for commercial
development use nowadays, although I do know an RF developer in
Brighton who still rates his one very highly and uses it daily.
Best wishes, Paul.
