Abstract

A method and apparatus for generating a desired pulse waveform including: dividing the desired pulse waveform into a plurality of line segments; assigning to each line segment at least a segment identification, a segment initial value, and a segment duration to form a waveform description; providing the waveform description to a pulse generator. The pulse generator is operable to produce a waveform corresponding to the waveform description and to output the produced waveform.

Claims (15)

1. A method for generating a pulse waveform, said method comprising:

dividing a desired waveform into a plurality of line segments;

describing each line segment by at least a segment identification, a segment initial value, and a segment duration to form a digital waveform description;

providing said digital waveform description to a digitally controlled pulse generator, said digitally controlled pulse generator being operable to produce a waveform corresponding to said digital waveform description in response to said digital waveform description; and

outputting said produced waveform.

2. A method according to claim 1 , wherein each line segment description is further assigned a trigger value, said trigger value being operable to synchronize another pulse waveform.

3. A method according to claim 1 , wherein each line segment description is further assigned an impedance state, said impedance state permitting a simulation of said pulse generator being disconnected from an output connection.

4. A waveform generator for generating a pulse waveform, said waveform generator comprising:

a digitally controlled pulse generator; and

a controller, said controller:

dividing said desired waveform into a plurality of line segments;

describing each line segment by at least a segment identification, a segment initial value, and a segment duration to form a digital waveform description; and

providing said digital waveform description to said digitally controlled pulse generator, said digitally controlled pulse generator being operable to produce an output corresponding to said digital waveform description in response to said digital waveform description, whereby said pulse waveform is output.

5. A waveform generator according to claim 4 , wherein each line segment description is further assigned a trigger value, said trigger value being operable to synchronize another pulse waveform.

6. A waveform generator according to claim 4 , wherein each line segment description is further assigned an impedance state, said impedance state permitting a simulation of said waveform generator being disconnected from an output connection.
