Re: Spectrum analyzer Tektronix 7L13 on mainframe Tektronix 7603
This is very interesting to me, but the description of the device on the eBay sale page is very difficult to follow. They discuss spectrum analyzers as if this is one. I don't see how that can be.toggle quoted messageShow quoted text
However, even if it is only a "flat" white noise source, I can see the utility it offers. My normal MO for testing receivers is to use my Marconi generator swept over the required spectral range while observing the output of interest on my 7000 series 'scope. This works quite well, but can be somewhat cumbersome. I have considered trying to acquire a tracking generator for my 7L12, but those are relatively rare and have been somewhat expensive.
I never considered using a broadband noise source as an alternative to the tracking generator. From your post, it appears that you have done so, with at least acceptable results.
It's kind of funny, because I work more in audio than RF and for years, prior to the advent of low cost computer "sound card" based analyzers with tracking generator, used noise with an analyzer for sound system measurements. Duh.
Any comments, hints or suggestions welcome.
