37 Introducing Infiniium DSO/DSA90000A Series Top Five Market Needs Infiniium 90000A Series Addresses: You have great signal integrity, but need a little more memory to capture my entire signal. I need a scope which support full BW on all channels. 1Gpts per Channel Ultra Responsive Deep Memory 13GHz BW & 40GSa/s sampling rate on All Channels Your InfiniiScan is great, but I need to capture infrequent events and signals as well. A scope is a large ADC to me. With longer memory, the speed of data transfer is critical. I want a bit more visibility with your display. Industry s Only 3 Level Sequence Trigger System combining HW Trigger & InfiniiScan SW Trigger Industry Leading Data Transfer Speed Industry leading 12.1 inch XGA Display 90000A Series Continues to Deliver the Following Values: I need a scope telling me the truth about my signal. I need accuracy and repeatability! Scopes are so expensive these days. Can anybody give me a true investment protection?
