The Agilent DSO90254A 4 Ch 2.5 GHz Infiniium Oscilloscope boasts an ever-expanding set of measurement applications for serial debugging and protocol viewing, jitter testing, advanced triggering, measurement customization, and rapid automation. With 1 Gbyte of memory, low-frequency jitter components can be more quickly resolved in a single measurement. Statistical accuracy is improved with more data collection. Agilent's integrated deep memory remains responsive and allows more comprehensive testing, supporting pattern lengths up to PRBS23 for accurate transmitter and receiver results. Infiniium's built-in FFT allows users to quickly and easily analyze the frequency components of their signals. A resolution bandwidth of 6 kHz is supported with the standard 10 Megabytes of acquisition memory at the maximum sample rate of 40 GSa/s. Display: 12.1-inch color XGA TFT-LCD with touch screen.
