What is dynamic range?

re:What is dynamic range? 
The dynamic range specification determines whether or not low-level signals will be visible in the presence of large signals and therefore is one of the most important performance figures for a spectrum analyzer

re:What is dynamic range? 
Dynamic range limits the range of signal amplitudes that we can measure with a spectrum analyzer.

re:What is dynamic range?Best Answer!
Two types of noise contribute to dynamic range: phase noise and sensitivity. The Displayed Average Noise Level (DANL) or noise floor (sensitivity), determines the smallest signal that can be measured on the spectrum analyzer. Phase noise (also know as sideband noise) is the key parameter when measuring two signals that are close in frequency.

Which Spectrum analyzer have you used that has the best dynamic range?

re:What is dynamic range? 
There is a lot of good spectrum analyzers out in the market today with good dynamic range. The key really is what testing you are doing with your spectrum analyzer. The Agilent X series has quite a few good units. Today I use the high end PSA or the Agilent E4440A. it has a dynamic range down to -156dBm with a analysis Bandwidth of 40MHz

I have the PSA E4440A too. I was looking into the MXA series as a cheaper solution but the PSA still works for our needs. The new PXA looks interesting though.

re:What is dynamic range? 
Ya. I have seen the PXA. Really nice box. My Agilent guy brought it over for a demo. It has the best DANL and Phase noise and is like 2x faster than a PSA. I am looking at trading in our PSA for the PXA as Agilent is offering an attractive offer for a trade up.

re:What is dynamic range? 
thank is good to know. I will ask my Agilent rep about the trade in. Thanks.

What is the model number of the PXA?

re:What is dynamic range? 
The PXA model number is N9030A and you have to choose your frequency option like the MXA. Option 526 is 26GHz. So it would be a N9030A-526

Thanks for the info!
