The TDS6604 DSO is a four-channel, real-time instrument that offers an unprecedented 6 GHz bandwidth as well as a simultaneous 20 GS/s sample rate on 2 channels. With its ability to support single shot acquisition at 6 GHz, the TDS6604 is the first oscilloscope with multiple-channel acquisition at such speeds. This exceptional performance is key to high-speed signal integrity measurement work; it enables accurate capture of the brief transients and fast signal edges that affect digital system performance.
