if you are a beginner...

hello my unknown friends,
if you are a beginner what oscilloscope you'll buy ? conditions :
- for hobby (ham utility)
- enough monney (1000 pounds)
- new/used
-or maybe a spectrum analyzer
thanks
janoc:
There are plenty of "Which oscilloscope should I buy" threads around, just search the forum.
Spectrum analyzer you are not likely to need if you are only starting (or more likely - not have the money for - even old used ones still go for $1500-$2000 ...). Get a decent scope instead and either use the FFT function on it or capture the data on an USB stick and analyze it on the PC. It is less "real-time" than a real spectrum analyzer but you can do a lot more e.g. in Matlab or with something like Python.
tggzzz:
As jaonc said, read the posts on the forum, and then you will be able to ask interesting questions that can be answered.
First work out what you need to measure. Then choose the best tool for that.
Hams "work" in the frequency domain, where low noise, wide dynamic range and low distortion are very important. Scopes are a poor fit for each of those attributes; spectrum analysers are a better fit.

many thanks for your answer
I don't understand the type/name of oscilloscope, do you ?
you said nothing (I have search engines , I want an answer not words )
Rerouter:
If you are a beginner, go to your local ham meetups, get familiar with which tools the other members use, and once your familiar with them, you can better define what will suite your needs.
any of us saying to get a 100Mhz rigol, while good for an electronics beginner may not meet the same criteria as for Ham activities such as tuning filters, and following modulation / demodulation paths. this is more the role of a spectrum analyser, but these still tend to cost significantly more than beginner level scopes.
Oscilloscope FFT displays of spectrum may get you by, but i personally have not even got a DSO, nor do I do ham activities, so I cannot answer with your limited requirements
The best thing you can do to get a solid answer is spec out what you need to measure, with this knowledge, people without ham experience can then chime in.
