Hi, Everything depends on how much you want to spend.
Think that a spectrum analyzer (SA) does not analyze protocols, but rather it will help you to check the RF front end. If you go to the IEEE 802.15.4 standard you will find a special chapter in which all the RF parameters are defined (for the TX things like distortion, or sensitivity for the RX). I do not if this is what you are thinking on... On the other hand if you want to measure the EM fields on the air, then a SA is also useful but then you need an extra option which is a filter bank, otherwise you may saturate the input mixer if the antenna has a big bandwith and the air is very populated. Regarding the protocols, I am not sure what you mean. If you want to demodulate the signal into the IQ components, then you need some kind of vector signal analysis, that may be a whole equipement or just a card that can be embedded in a regular SA. Finally, if you do not take care so much of the RF but rather you are interested in the MAC protocols, then you could use a USB sniffer that will provide much information of the packets sent between motes. I hope this helps you!
