Abstract
A method, and circuit for implementing the method, allow a deep memory digital oscilloscope or logic analyzer to rapidly display large data records. Incoming signals are "dually" processed through multiple data compression circuits so as to create and store at least two data records. A smaller record is available for immediate and rapid display. A larger record is available for subsequent panning & zooming. By storing sequential data records in alternating memory divisions and eliminating data moves, the larger record may also be viewed more rapidly.
