HP'S NEW TIME INTERVAL MEASUREMENT SOLUTION
The HP 1726A Time [nterval Oscilloscope is a new time interval measuring instrument. Time interval counter (
and oscilloscope technologies have been synergistically combined in the 1726A to offer performance,
convenience, and value unmatched by alternative instrumentation. The contributions of the Time Interval
Oscilloscope benefit users with frequently encountered timing applications and/or precise timing
measurement requirements.
The requirement for stringent timing measurements has resulted from advances in IC design, device
characterization of custom integrated circuits (e.g., bipolar and MO5 processes), ECL circuits, and faster
clock speeds in computers and other electronic systems. For example, characterizing a'process, verifying
system operation, or troubleshooting a new design all require highly accurate and repeatable measurements.
The feature set of the 1726A provides advanced performance with simple setup and the front panel
conveniences expected from Hewlett-Packard products,
