protocol Analyser / Bus analyser
-
Hi to All, I wanted some information or idea on protocol analyzer (Bus analyzer).... Can anyone please give me a brief idea on Bus Analyser... I want to know what is it and how it works..like (I have read that bus analyzer comes with a hw and sw....now how anyone connects it..to USB?..and how we can analyze) One small example would be very very great... Thanks in advance.

Did you even bother to type "USB bus analyzer[^]" into Google or Yahoo before posting such a basic question?

No actually I tried...But it shows different vendors or software available for that.....I have not got any generic explanation for it...like how it works and what it does...

That's where you go to the vendor web sites and read documentation on these things so you get a better idea of what you're looking at.

A protocol analyzer sits either in the middle of a connection, passing data through, or TEE-d into the connection. In general terms there is either a hardware/software component (newer), or a hardware stand alone system (older). Some systems can be said to be software only (e.g. TCP/IP, USB), but since that puts the computer in the middle, there is still a hardware component requirement (i.e multiple ports, etc). You can get them for RS-232, RS-485, USB, I2C, etc, pretty much any type of data stream. They sit on the desired communication bus, and provide knowledge of data, and depending on the type of communications, the control signals/data as well. They are used to monitor, or debug communications between systems. The other analyzer that might be what your thinking of for bus monitoring is a Logic State Analyzer or LSA. That involves individual or bus connections to monitor logic levels (i.e. tapping into the DMA bus of a computer, and monitoring the data flow. Two different things for different needs, the LSA is far more into the hardware of the beast, while the Protocol analyzer sits between the beasts. Neither are complicated to use, just complicated to really understand and analyze what you are getting back from them. For a better explanation, try http://en.wikipedia.org/wiki/Bus_analyzer[^]. Hope that helps a bit, although the other reply thread does have a point, but hey, it's Christmas.

Yep, I guess you are. If you really want to play, then you hook the HW part of the analyser up to the bus, then you connect the analyser to another PC (normally) which has their SW on it, to capture the bus data for analysis. And a USB analyser is really, really painfull to analyse,. At a bus level the USB protocol is painfull.
