[Milsurplus] Tektronix Oscilloscope Model 545

[Floyd Petri]

I have received so many good answers to my request about a 545 and some 
advice not to use one that I now feel it necessary to offer an explanation 
in order to get the final answers I need.

Fist of all I have a 1L20 Spectrum Analyzer plug in unit which is why I need 
a 545 scope or one that unit will plug into.  I want to buy a reasonable 
priced 545 or something that will use the plug in unit within my driving 
range for pickup if possible.  Chester, Texas 75936.

I am a poor boy operating on a shoe string so all those nice HP scopes are 
out of my reach and I actually need a spectrum analyzer.

My real goal is a Spectrum Analyzer in the frequencies that I need.  The 
1L20 seems to cover exactly what I need.

I want to use the Tektronix Oscilloscope with the 1L20 Spectrum Analyzer for 
a home Radio Astronomy project I am working on.

That being said, I am sure that advice can now be tailored to my needs. 
Thanks to everyone who is helping.  I have submitted my request to TekScopes 
on yahoo and I am now waiting for a reply to join.
