Beagle I2C/SPI Protocol Analyzer

Completely lived up to my expectations, just plug it in, install the software, and go. Data Center was intuitive and easy to configure, and I was into debugging my I2C issues within 10 minutes of opening the box.

Does a good job in parsing I2c packets

Does a good job in parsing I2c packets, however sometimes I see it
fails to properly parse the most significant nibble of a byte. And for some reason, it keeps picking up some glitches as a start condition.

Intuitive interface, was able to quickly find what I needed.

Works perfectly

What more is there to say. It works out of the box. Small, compact, no need to carry around a scope.

Took my new engineers less than 5 min to start capturing data - great tool for I2C or IPMI busses.

Was able to verify my writes from host processor to I²C camera, affordable price, easy to use.

A nice I2C Analyzer
2018-12-29
What I like about this I2C analyzer is that it detects errors and it shows the data for each packet. In my situation, I had nothing but good packets. What I was looking for was bad data. I had an I2C analog to digital chip sending out bogus data intermittently. The input was zero volts and ever so often it would send out a value that was not zero. You need an I2C analyzer to see what the actual value was in order to verify you had the error.
I bought the accessory cables that go with the unit. I bought both the pin version and the hook version of the cables needed to interface with the unit. The extra cost was insignificant to the cost of the issue I had which was stopping our production line. The cables were well marked with their function names on the wires (GND, SCK, SD). There were two wires marked ground; I hooked up both to my return line.
Once I started gathering data, it was easy to filter through the data looking for my error. The software was very helpful in filtering out data on the bus that was not for the address I was looking at. It also showed packet errors on my system (for which there were none in my case).
The analyzer cleaved out all the things that weren't wrong and led me to the what was wrong.
In all the analyzer and software combination was what I needed. You can buy of course O-scopes with this kind of feature, but you'd pay about $10K for it. This was quick and easy to use and was only $518.00 (including cables). To me, it was worth every penny as it solved my problem without breaking my wallet.
The software was very intuitive as I did not spend a lot of time going through the manual on how to use this analyzer. I am sure could have done a better job of filtering the data had I read the darn thing. I am glad though that the software was easy to manage.
The data log files it creates when collecting data can get quite large but not as large as I thought they would get. I actually collected data on the design over the weekend. The file ended up being 1.1g bytes. This is large but not as large as I expected. Because of all the data that it collected, the filtering part of the software became very important.
Overall, this is a good product. As I use it on other issues and become more familiar with the filtering process, I can probably give a better review. Currently though, I am quite happy with the product.

Good data rate, reliable operation

Rather a lifesaver
2018-07-01
I was recently implementing a project in which the processor needed to access a SPI memory via an I2C bus. While I wasn't able to watch both sides of the conversation at the same time, this analyzer did allow me to monitor both buses.
I would have awarded five stars but for two very annoying UI artifacts, related to "reminding you" that it's doing you a favor by changing the "protocol lens" when switching modes, and a scroll enable feature that won't stay enabled.
Would I buy another? Absolutely.

This has has not only helped to shorten our development cycle it has also enabled us shorten our communications test and validation time and ensuring a more robust/reliable product. Well worth the money.

Works as expected. No surprises

My Beagle Trace tool arrived the day after I placed the order and works as expected. I am already familiar with the Beagle tool and very satisfied with its usefulness.

Beagle I2C/SPI Protocol Analyzer Review
2016-03-21
I have had the opportunity to start using my newly purchased Beagle analyzer. As with all products from Total Phase, the unit installed without difficulty and I found it easy to use.
My only complaint is that the unit is sold without the 10-pin split cable: as I recall, my Aardvark unit was supplied with the cable included at no extra charge so I was expecting it to be included. However, no harm was done in this case as I am able to move the split cable between the two units as required.
Personally, I would have preferred a unit that combines the functions and capabilities of the Aardvark and Beagle units but I can live with having them separate.
Actually, when I purchased the Aardvark it was advertised as having a monitor function for I2C, which I have used extensively over the years. Albeit, it did not work well at 400 kHz due to its internal buffer filling up too quickly, but it was useful in many situations. At some point, Total Phase quietly issued a PC software update that removed the monitor function and so I started using two different PC software versions for different sessions: the old version for I2C monitoring and the latest version for everything else. That seemed a rather odd move and probably left quite a

It was easy getting started with Beagle, got the system analysed in minutes. Problem solved !

Excellent Tool
2016-02-24
Great job... Very nice tool. Probably the best out there.
Only one minor issue - would be nicer if you could hide "both" spi data streams when looking at miso and mosi. At present you can only display: both + miso + mosi. Would be better as: miso + mosi, or both.
Wish it was less expensive too :-)

Thank you

This did exactly as advertised. No issues installing drivers, etc., and the deep trace buffer helped us solve several issues we couldn't capture with a storage scope.

It is very helpful to analyze the I2C transaction.
Peter H.
Easily snooped an SPI interface with ten minutes of opening the box.
2014-09-07
Easy to use. Only one complaint: The timestamp on the transactions only has a single format of ss.mmm.uuu Other formats would be nice especially a microsecond only which would be easy to sort in a spreadsheet after export.
Otherwise this thing Rocks!

The tool does what I needed to do. It would be very interesting to let the user define device registry maps and populate the register values as they get captured (last written and last read).

Beagle I2C Analyzer easy to set up and take data
2014-05-07
After taking the Beagle out of the box, following the simple software installation, and connecting the board to my device under test, I was taking data in a few minutes. I ported the .csv file to Excel to analyze the data, and found my issue quickly. The device is simple, affordable, and flexible to work in a variety of applications. Thanks for a great product.
