Yes, that's always been its big selling point. 1GS/s real-time. > If not > (like other sampling scopes), perhaps they're just sliding the phase > of the A-D's while still clocking them within their rated specs. It also has a selectable equivalent time sampling mode (up to 10GS/s), but you have to specifically select this through a menu. In this mode the 1Mpoint memory comes in at 100ns/div. > Did you ever measure the clocks to the A-D chips? No, I haven't open my unit. But bet your bottom dollar they are 100MHz, simply no other way to do it.
