[DDiscovery: How to record with sample rate for duration?]

I want to record signals at 10 million samples per second for 5 seconds, but even after perusing the manual I'm at a loss on how to do this.

Apparently, base is not just the displayed duration per screen, but also the recording length, but after the fact?  Setting it to 5 s, and pressing record, 5 s is replaced by 1.6 us?!

And how to I set the sample rate?  I have "100 MHz x 32", but no other setting (unless I enable "advanced view").  With advanced view, I seem to have to compute the duration in my head by dividing samples per rate?!  Although that doesn't work, it seems to record for as long as I want it to.  So what does samples mean?

Also, having a bus with a clock, the data view seems to list every sample, not just the clock-active ones.  Is there any way to achieve this?  What I'd want is a list of values on the bus.

Well, I've seen enough to submit my order!  ?  Thanks again.

Thanks, Attila, those are excellent suggestions!  In fact, I didn't realize that the clock of a bus could be an extra signal not belonging to the bus! *duh*

But I have a silly question: Is is actually possible to use/generate mock data in demo mode, e.g., like the counter in your example?  This would allow me to really test those features.  Whenever I press Record or Run in demo mode, I only get 0s for data ...

Also, why are there Bus options to set the MSB and LSB if I cannot choose a smaller range that doesn't encompass all the signals?  What's the point?

If I could exclude a signal by narrowing the LSB/MSB range then that would solve my Bus and Clock problem described before.

What I understand by now is that I need to define a Custom "signal" that removes the Clock signal from the Bus value, but couldn't that be easier to begin with?

[Logic Analyzer and WaveForms: How does bus and clock work?]

Before buying a Digital Discovery, I decided to try out WaveForms first.  But as WaveForms doesn't provide any mock data, I cannot really confirm that my main use case is covered.

Suppose I define an 8-bit Bus DIO 0 to DIO 7 and set one of its signals DIO 0 as clock with rising trigger.  Does the clock signal become part of the bus value?  In other words, if DIO 1 through DIO 7 are constant HIGH and DIO 0 pulses, are the values shown in the data tab hFF or hFE?

If the clock signal is included in the bus value (hFF), is there any way to separate the clock signal from the bus?
