The Frequency define my adjuste.
I need a frequency counter or way to get frequency for a continuos
signal (TTL).
the Standar frequency is  732.4220  but i neead steps at least from
0.004 Hz.
I mean I nead most have the ability to see the diference for:
732.4236,  732.4220Hz,  732.4204 and 732.4187
Actualy we are using a counter model 53131A Universal Frequency
