AlexRiga Posted February 11, 2019 Share Posted February 11, 2019 Hello! Is there are any possibility to set pulse width for pattern? For example, i need to simulate 1kHz bus with 1us pulse width. See picture attached. Any tutorial about that? Sorry, i'm newbie here. Thanks in advance! Link to comment Share on other sites More sharing options...
attila Posted February 12, 2019 Share Posted February 12, 2019 Hi @AlexRiga You can use clock with 99.99% duty or configure pulse signal or custom pattern. To have more buffer for custom on Analog Discovery under Settings/ Device Manager select the 4th configuration. Link to comment Share on other sites More sharing options...
AlexRiga Posted February 12, 2019 Author Share Posted February 12, 2019 Hello @attila, many thanks for you reply! Spent half day figure out how to do that, without success I clearly understand, how to make sequental pulses (clock) with predefined pulsewidth. But how exactly to make custom pulse sequence/pattern (see pict attached) with predefined timing like captured? Maybe it is not even possible? Or maybe somehow i can use logic capture to preconfigure pattern generator? (probably in my dreams, huh ) Using Digital Discovery, not Analog Discovery...

attila Posted February 12, 2019 Share Posted February 12, 2019 Hi @AlexRiga Settings/ Device Manager/ 4th config Perform a capture with Logic Analyzer Export data Open Patterns, add signals, edit Import Select file, check column for signal adjust frequency as it was in Logic Analyzer. You may want to limit the imported signal to be periodic, like to 10k samples Do the same for the other signal. Select Auto Run and Repeat 1, or leave it with continuous if you need this way.

AlexRiga Posted February 12, 2019 Author Share Posted February 12, 2019 Thanks a lot! Will try it! Link to comment Share on other sites More sharing options...
AlexRiga Posted February 12, 2019 Author Share Posted February 12, 2019 Hi @attila Yes, it works! Export-Import super useful feature missed somehow ! But my question remains, how it possible to setup manually custom pattern with specific timings? Link to comment Share on other sites More sharing options...
attila Posted February 13, 2019 Share Posted February 13, 2019 Hi @AlexRiga The custom pattern can be edited in the interface, with mouse on the signal, prefill generated (pulse, random or counter fur bus), edited in the table on the right side, signal imported from csv, txt files. Here 1MHz sample rate, with prefill of pulse 1 low and 999 high will generate 1us low, 1kHz signal Link to comment Share on other sites More sharing options...
