@attila To clarify, what we're really looking for is something like a single buffer acquisition in which the buffer size is 134,217,728 instead of 131,072? If this is not possible, then how do we achieve the recording of 134,217,728 samples at 50MHz? Thanks, Rob

Thanks @attila Using the Waveforms SDK, how do I setup the device in order to use this mode and additional recording buffer? We're not using the GUI. Thanks. Rob

Hello @JColvin and @attila As mentioned earlier in this thread, I'm using the AD Pro to measure and log data. It appears to have two configurations: We're using Config 2 with the larger AnalogIn buffer. I'm curious, the device is advertised as having 128MS total, yet adding up all the buffers in Config 2 totals about 410k. Is there a way for me to record data at a sampling rate greater than what can be streamed back to my PC via USB, and use a larger Analog In buffer than 131072 samples? I was under the impression I would have a much larger buffer to be able to utilize while logging data. Thanks, Rob

Thanks @JColvin. Where in the SDK documentation can I find the definitions of the different idxCfg options to use with FDwfDeviceConfigOpen? Thanks, Rob

Hi @JColvin. Thanks for the response. I'm prototyping with the Analog Discovery 2 and Waveforms SDK right now. It's really cool and easy to use. One question for you: I noticed the max buffer size is 8192 (using the FDwfAnalogInBufferSizeInfo function). We're using a minimum acquisition frequency of 1MHz, and filterDecimate, so every 100th ADC acquisition is stored (100M / 1M). Does this mean the maximum amount of time data we can store is 8192 * (1/1M) = 8.192ms? Just want to double check my math. If we need to capture and store more data, and cannot change the acquisition frequency or filter type, how do we go about doing this? Is there another piece of hardware to use, or some other API call I should look into? Thanks, Rob

Hello, I'm looking to buy a piece of hardware that can do the following: -USB2.0 bus for communication to my PC -At least one analog in channel (single ended or differential), >=1MS/s, >=12 bit resolution - Python compatible SDK Can you confirm the Analog Discovery 2 is the right one to use? The Python API just needs to start and stop a reading, and send the data back to the host. Thanks, Rob
