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.

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.
