Spectrum analyzers' prices

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

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

What is the main parameters in selecting SA?

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

Hi,

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

companies like agilent have a huge engineering/marketing base to support, and it is YOU that does the supporting by buying overpriced gear. Their S50K spectrum analyzer should probably be priced at S20K for the features it actually has. For that S20K "value", you would get better phase noise, bigger dynamic range, smaller frequency step size, and perhaps a little more rugged and repeatable design. For S5K 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.
