Patent ID: 7353126

Claim:
A method of determining coherent test conditions, said method comprising: receiving constraints from a user, wherein said constraints include desired test conditions, desired tolerances for said desired test conditions, and desired instrument; determining said coherent test conditions using said constraints, wherein said determining said coherent test conditions includes determining a calculated sampling frequency and a calculated analog frequency; and providing each determined coherent test condition to said user, wherein each determined coherent test condition includes said calculated sampling frequency and said calculated analog frequency, wherein said constraints include a first range of desired number of samples, wherein said desired conditions include a desired sampling frequency and a desired analog frequency, and wherein said determining said coherent test conditions comprises: selecting a sample value from said first range; determining a second range of integer number of cycles for coherency using said sample value, said desired sampling frequency, and said desired analog frequency; selecting an integer value from said second range; if said selected sample value and said selected integer value satisfy requirement for coherency, determining an ideal sampling frequency using said selected sample value, said selected integer value, and said desired sampling frequency; using a clock divider value and said ideal sampling frequency to determine said calculated sampling frequency and said calculated analog frequency; and retaining said calculated sampling frequency and said calculated analog frequency if fall within desired tolerances.
