Sniffing the Rigol's internal I2C bus

<< < (727/899) > >>

I have the MSO1074Z-S and I agree with your comments Manuel. The I2C decoding is almost not worth having at all, and certainly as a paid for option I'd feel short-changed.

Over all, like you, I do consider it good value for money though, there's a lot of functionality in that box when you include 4 channels, the LA and the dual signal generator.

Rigby:
Forget using a cheap scope for protocol debugging.  Get a Saleae product and live happier.  I'm not shilling for them, just a very happy customer.

I agree with Rigby, if you are measuring an already working protocol, a protocol analyzer is your thing.

If however you are prototyping a board that uses i2c, you need the scope to make sure your signals are good. The protocol analyzer will only work on clean signals.

How good is the analog mode on the Saleae analyzers, is it just a gimmic or is it eqvivalent to usb-oscilloscope with lower bandwidth?

miguelvp:
I guess you made your point :)
