Analog Discovery Pro 3000 Series: ADP3250/ADP3450 Record Mode Sample Rate
Hi,
I am thinking about buying one of the Analog Discovery Pro oszilloscopes (ADP3250/ADP3450). I want to make sure, that the device is suitable for my measurement application: I want to sample an analog signal with 5 MHz (1 Channel). 14 Bit resolution should be enough. I want to record the signal continiously. If this is not possible, then at least for 5 seconds. Unfortunately this is not possible with a standard oszilloscope. I want to transfer the data to my PC for further processing.
Hi @oeser
At 5MHz you could record up to 26 seconds (128Mi samples) reliably.
The samples are stored at 16bit resolution, so with sample rate below ADCs 100/125MHz averaged samples will improve the resolution.
In Standard, Linux and Embedded mode the recording length is unlimited with custom application/script.
The rate is limited by the (USB, Eth, AXI) bandwidth and latency, since a too long delay may cause device buffer overflow.
In Standard mode it will use additional 128M
