If any of the supplies should trip, they are all instantly disconnected. Linden wrote: I've been using a CS328A USB MSO for a few years now and my decision to purchase it over some less expensive units has been validated time and time again.
We find it invaluable for I2S and SPI issues, and it also has CAN, I2C, SPI and RS232 decoders built into the software. Scott Whitney also likes the , and is a 34 channel analyzer via USB connection, with 500MHz timing mode or 200MHz state mode.
The cool thing about it is that it provides complex triggering, and directly decodes CAN, I2C, SPI, and RS232 data streams.
It also has a beautiful and intuitive user interface that seems leaps beyond the others I've looked at.
In particular, I find the time and voltage scales that are displayed on the edges of the graph to be very useful.
