The Siglent SDS2000X series of oscilloscopes supports samplerates of 2GSa/s, up to 4 analog channels with up to 300MHz bandwidth, and up to 16 logic channels with up to 500MSa/s.
See Siglent SDS2000X series/Info for more details (such as lsusb -v output) about the device.
Hardware
The Siglent SDS2000X series oscilloscopes are capable of sampling up to 2GSa/s 140 Mpts/CH memory for the analog channels. Due to the fact that the 2 channels are shared, if both channels are on the sampling is limited to 1GSa/s and 70 Mpts/CH memory per channel. This is also true with the 4 channel devices. The analog channels have history memory where 80000 frames are stored and can be viewed via the scopes History function.
All devices have the logic analyzer and DDS arbitrary waveform generator built-in. Keep in mind that for the logic analyzer and waveform generator an extra software option must be purchased. For the logic analyzer an additional probe device (SPL2016) must also be purchased. The logic analyzer is capable 500 MSa/s with 140 Mpts/CH memory.
The older series SDS2000X Logic Analyzer function does not support acquisition of the LA channels over VXI or USB. Due to flash memory program limitations the code for this function does not fit. Its not clear if newer "E" scopes will come functionality for the SDS2000 series scopes.
An extra software option to decode serial protocols is also available on all devices.
