Fw: Re: Fw: Re: [Test-Equipment] Spectrum Analyzer BW measurement

[Gary Schafer]

I have an old HP 141 analyzer. Filters are probably not that sharp. My 
filter switch is dirty and acting up now so could not measure all. Here 
is what I measured on a couple:

100 kc filter -3 db   600 kc @ -50 db
10  kc filter -3 db   100 kc @ -50 db
30  kc filter -3 db   275 kc @ -50 db
  3  kc filter -3 db    30 kc @ -50 db
