Abstract
Disclosed is a timing generator including a frequency generator for generating an output signal, and circuitry for providing a nominal parameter setting value to the frequency generator for setting a nominal value of a parameter of the output signal, such as frequency, delay time and/or pulse width. The timing generator further includes a memory for storing predefined parameter setting values, whereby the memory is directly coupled to the frequency generator for directly applying parameter setting values stored in the memory to the frequency generator for modifying the nominal value of the parameter.
Claims11
A timing generator comprising:
- a frequency generator for generating an output signal;
- a microprocessor for generating a nominal parameter value signal;
- a memory for storing and generating a parameter variation value signal;
- and
- a coupler for combining said nominal parameter value signal and said parameter variation value signal and providing the combined signals to said frequency generator, to cause said output signal from said frequency generator to vary over time from an ideal signal produced by said nominal parameter value signal alone.
A method for providing a non-ideal timing signal from a frequency generator, comprising:
- generating a nominal parameter value signal;
- generating a parameter variation value signal;
- coupling said nominal parameter value signal and said parameter variation value signal;
- and
- providing the coupled signals to said frequency generator, to cause said output signal from said frequency generator to vary over time from an ideal signal produced by said nominal parameter value signal alone.
A timing generator comprising:
- a frequency generator for generating an output signal, said frequency generator receiving both a nominal parameter setting value for setting a nominal value of a parameter of said output signal and a predefined parameter setting value for modifying said nominal parameter setting value to cause said output signal to vary with time in order to emulate a signal being subject to at least one deviation.
