Claim 1
Independent Claim
120 words
A method for producing a low-speed pulse output channel synchronized with a full-speed pulse output channel, the method comprising the steps of: storing a first pattern in a pattern RAM of a first channel, the first pattern representing a desired full-speed pulse output; storing a second pattern in a pattern RAM of a second channel, the second pattern representing a desired low-speed pulse output and having N times as many bits representing each part of the first pattern, where N is a power-of-two; and employing a common controllable timebase to clock both the first and second patterns through a digital means for changing a data pattern to a pulse by a process that is synchronized by the common controllable timebase.
Claim 2

Claim 4
Independent Claim
80 words
A method for controlling the timing of a burst of pulses synchronized to an external timebase, the method comprising the steps of: synchronizing an internal timebase to the external timebase; receiving a frame sync input; opening a gate to permit distribution of the internal timebase signals to pulse generation circuitry in response to receiving the frame sync input; and generating the burst of pulses synchronized to the external timebase when the pulse generation circuitry receives the distributed internal timebase signals.
Claim 5
Independent Claim
80 words
A method for controlling the timing of a burst of pulses synchronized to an external timebase, the method comprising the steps of: synchronizing an internal timebase to the external timebase; receiving a frame sync input; opening a gate to permit distribution of the internal timebase signals to pulse generation circuitry in response to receiving the frame sync input; and generating the burst of pulses synchronized to the external timebase when the pulse generation circuitry receives the distributed internal timebase signals.
Claim 6
Dependent Claim
71 words
A method according to claim 3 wherein the synchronizing step comprises the steps of: frequency dividing the external timebase by a first constant; frequency dividing the internal timebase by a second constant; generating a voltage indicative of a phase frequency comparison between the frequency divided external and internal timebases; and controlling an output frequency of a voltage controlled oscillator with the voltage from the generating step to produce the internal timebase.
Claim 7
Dependent Claim
60 words
A method according to claim 3 wherein the generating step comprises the steps of: storing a pattern indicative of a pulse's period, width and phase; determining a timing of edges of the pulse from the stored pattern according to synchronization with the internal timebase; and repeating the determining step a specified number of times to produce the burst of pulses.
Claim 8
Dependent Claim
74 words
A method according to claim 5 wherein the determining step comprises the steps of: accessing the pattern and producing a serial bit stream indicative of the pulse's period, width and phase; producing a leading edge signal and a trailing edge signal from the serial bit stream; adjusting edge placement of the leading edge signal and the trailing edge signal; and creating a pulse from the adjusted leading edge signal and adjusted trailing edge signal.
