attila Posted June 27, 2018 Share Posted June 27, 2018 Hi @mary0202 I'm not sure if I understand your questions. The Scope interface can Record up to 10M samples at up to 1-2MHz: Link to comment Share on other sites More sharing options...
mary0202 Posted June 28, 2018 Author Share Posted June 28, 2018 Sorry for lack of explanation. How is record mode acquiring and recording data continuously? How is the buffer working? Link to comment Share on other sites More sharing options...
attila Posted June 29, 2018 Share Posted June 29, 2018 Hi @mary0202 The Scope buffer on Analog Discovery is 8-16k samples / channel. The single/repeated acquisition mode can capture at up to 100MHz rate a buffer of data. Then this is transferred to the software for display and processing. The record mode streams data to the software at up to 1-2MHz rate, limited by USB bandwidth. In WaveForms application the record length it is limited to 10M samples / channel, for memory usage and processing time considerations. Link to comment Share on other sites More sharing options...
mary0202 Posted July 5, 2018 Author Share Posted July 5, 2018 Does the data always stream or does it stream when the buffer is full? Link to comment Share on other sites More sharing options...
attila Posted July 6, 2018 Share Posted July 6, 2018 Hi @mary0202 Since there are multiple instruments sharing the same USB device, the streaming is actually performed by transferring chunks of data. In case the device buffer gets full, due to high sample rate or other instruments, applications, devices blocking the record process, the application will warn with "samples lost" message.
