OK we have  3rd order intercept for mixers & amplifiers but when evaluating a spectrum analyser i would probably not measure any of its internal signals  nut compare shoulder width and noise levels on signals

All but direct sampling spectrum analyzers are built around mixer(s). So you want to know not only max input power limit, but also 3rd order intercept and 1dB compression point.

regarding  VNA  i decided i did not require a full VNA system at home  as it takes up a big chunk of space  but the NanoVNA is defiantly worth looking at regarding the line

Proper VNAs are usually out of reach for most hobbyists. Well, perhaps except mentioned SVA1015X? NanoVNA looks like toy, but actually it is very capable device, especially considering it's price.

I do run 2 systems of  HP 70000 spectrum analysers that are not budget items but the big problem with lab equipment is it is BIG

Better have big old "boat anchor" instrument rather than something small that only pretends to be one.

Again - spectrum monitoring thingy. Can it do spectrum analysis with following settings: RBW=9KHz, VBW=10KHz, Start=150KHz, Stop=30MHz, Detector=Quazi-Peak? The same question for SDR's mentioned.

But SVA1015X is a SA and VNA however the latest fad is to get the bit cheaper SSA3021X Plus and enhance it to SVA1032X.
Well featured benchtop 3.2 GHz SA and VNA in a single package for $1600, what's not to like ?
And you can use all its functionality on a PC anywhere on the globe via the inbuilt webserver.

Hi all how do you do the reference to earlier posting  as in the part that is in a Blue Frame

for less than $ 1000 you can get a real spectrum analyser pre selected to 22 GHz
regarding VNA these are also available including generator to 1300 Mhz for about $1000
but we can talk about second hand equipment on a different / new Topic

You use the 'Quote' button, then edit the text so it looks like this:

Ja, i can use a cheap SDR dongle as a simple spectrum analyzer.
Thanks a lot !
