Goodwill spectrum analyzer is around 5000$,and Tektronix Real Time Spectrum analyzer is 24,000$ ,HP is around 50,000$ and R&Sch is around 12,000$!

What makes this differences in price? name or mark? technical diff?

What is the main parameters in selecting SA?
 

spectrum analyzer

I think durability and accuracy are the main differences. Also, after sale calibration and service.
 

Re: spectrum analyzer

Hi,

It depends on application you have. You can check the attached file to see the difference.
 

Re: spectrum analyzer

companies like agilent have a huge engineering/marketing base to support, and it is YOU that does the supporting by buying overpriced gear. Their $50K spectrum analyzer should probably be priced at $20K for the features it actually has. For that $20K "value", you would get better phase noise, bigger dynamic range, smaller frequency step size, and perhaps a little more rugged and repeatable design. For $5K you get the same circuitry, maybe 20 dB worse phae noise, 15 dB less dynamic range, a little more tendancy to drift between calibration.

If you do not need all that performance, go cheaper. If you have unlimited funds, buy the cadillac.
