Agilent Technologies 89600 manual Operating region with span and memory constraints

In full rate sample mode with the use of appropriate lowpass filtering (Table

3)signal aliasing is completely avoided. In this case the “Operating Region” is renamed “Alias Exposure Free Zone” to indicate this special condition. NOTE: Does not apply to HF operation.

Although the operating regions for all digitizer models are similar, each model or model family may have important differences in their operating region curves due to differences in maximum sample rate, front-end analog performance, and memory option. Appendix C provides the operating curves for all supported digi- tizers and most memory options.

Figure 6. The true operating region is fully described when constrained by all the previous parameters: number of frequency points, span, and digitizer memory. See Appendix C for operating region charts for the various supported digitizers.
