Older, second hand spectrum analyzers, HP-8562A and Tektronix 2712
xzswq21:
What do you think about HP8568A in this era? It's only $500 so it's an affordable choice for me! I have found Tektronix 2712 and the price is only $500, could you please help me to find a spectrum analyzer under $800? frequency band from 10KHz or 100KHz to some hundreds of KHz, I want to measure the linearity of some sensors and publish the results in a journal, thanks
xzswq21:
Sorry for posting again, which one is better? A new Rigol DSA705 or a used HP8560 or Agilent E4402B?
Neganur:
I think you should rather make a new post, your questions are awfully specific around your project and not so much about older second hand analyzers.
You are throwing a lot of model numbers around you while stating you only need 10 kHz or maybe 100 kHz to "some hundreds" of kHz. Perhaps those RF spectrum analyzers here in this thread are not what you need.
I would also point out that if your intention is to publish a paper (scientific...?) you better get something that is calibrated/accredited or you risk that your results are useless.
With that said, I'd take the 8560 (A? E? EL? EC? which model exactly?) if it's $500 and guaranteed working...it is the better instrument by a mile*.

*: except for absolute amplitude accuracy, in which case the ESA is better. But the ESA is worse in every other aspect.

No one can answer a question like this for you. You have to know what you want to do, then understand what you need to do it. If you are considering an instrument like HP, Tektronix, Anritsu, R&S, etc., just look at the specs. They will do what the specs say. I have an HP8642A and a E4404B. Which one I turn on (assuming I want to use a spectrum analyzer) depends on what I'm doing. If I was measuring the "linearity of some sensors" I might not use either of these but a different type of instrument.
