Title: Rigol DS1054z and I2C, RS232 and SPI
Post by: skyjumper on March 25, 2015, 09:10:41 pm
Hi All...

I have watched Dave's videos about the 1054z and its spiffy it is, so I just ordered one. One of the interesting features mentioned is that it can decode RS232, I2C and SPI which would be great for me. But in Dave's teardown video he showed where two buttons were omitted from this model, and those were the two related to logic analyzer features. 

So I'm confused... What can this DSO not do? I have a Salee Logic 16 I use extensively to help debug embedded code I write but I find it annoying having to use my PC. Would I be correct to think that the DSO can decode the data but not measure logic pulses?

The DS1054Z comes without logic port and logic probe. they are available on MSO1000Z series.
From what we know the MSO1054Z will not be available.

Okay, so how does it decode I2C and SPI?

probably RTFM would help.
MATH > DECODE and then use the probes on clock/data

In Europe:
RIGOL SA-DS1000Z, RS232/UART,I2C,SPI Trigger and Decoding function
Euro 136 + VAT

by the way, you should have all options active for certain time

I did a video on I2C decode on the DS1000Z series here http://youtu.be/HxpSYlnEDos (http://youtu.be/HxpSYlnEDos)

SPI and RS232 follow the same principles.

Don't expect to decode lots of RS232 data. It seems to decode only the waveform data visible on the scope display. At 115200 baud, I was able to decode about a max of 30 characters. The Saleae is *so* much better at this sort of thing, it's not even funny. If you want to sync the two up, run the trigger out on the scope to one of the unused digital inputs on the Saleae.

Your pretty good at that video thing.
