Siglent's SDS1000CFL family of scopes offer faster sampling rates and higher bandwidths than other Siglent SDS1000 families of scopes. The CFL's provide up to four channels with an external trigger input channel and bandwidths up to 300 MHz. With a set of separate vertical controls for each input channel, you don't need to worry about accidentally modifying the wrong trace. No more switching between channels as found in some other 2 and 4 channel oscilloscopes. Powerful triggering and analysis capabilities make it easy to capture and analyze waveforms, greatly improving the test efficiency.
