One of the most important features of high-speed digitizers and
digital storage oscilloscopes (DSO) is the available onboard
acquisition memory. Given the fast sampling rates of today's
high-speed instruments, it is important to store the data in the
instrument's onboard memory before transferring the data to the
PC for further analysis, data storage, and display or
distribution. GPIB-based DSOs outpaced the 1-8 MB/s transfer
rate of the IEEE 488.2 bus long ago, and today's high-speed
digitizers out perform the 132 MB/s transfer rate of the PCI
bus, especially in applications that require multiple channel or
high-resolution acquisitions. High-speed digitizers with deep
memory enable you to efficiently automate your oscilloscope
measurements while allowing you to: - Maintain high sampling
rates - Increase frequency resolution - Prevent aliasing -
Integrate with other instrumentation 2. Maintain High Sampling
