DSO / logic analyzer buying advice
I have a pair of instruments that one can't live without the other:
- HP16500C with HP16505A and lots and lots of options - This is my
"heavy gun". I can connect it to my PC's bus and see what code it is
executing. But don't have I2C, serial and SPI decoding.
- Saleae (clone) - Only 8 channels, but I can decode serial, I2C,
SPI, CAN, TWI and lots of other protocols
Those little 8 channel units are just so
impressive. Since getting one,
I have gotten a second one (clone, for trips), and the 1650A and Tek LAs
have yet to be out of mothballs after the move.
I have a 2465 Tek (I think that's the model), 4 channel 300MHz analog
scope, and even if you adds all 5 units up, I have less than $600 in all
of it.
I seriously considered a 1102 (I forget the brand, but we've talked
about it here recently), but I am still debating about it and a complete
PC scope.
I like the idea of a standalone device, but it seems I am never far from
my computer anymore, and it's easier to take on computer show trips and
help people hacking on new projects if it's not standalone.
