Sample Rate (Digital Input)
Digital data from the Logic analyzer represents a numerical quantity sampled at periodic time intervals. The VSA can not determine the true from the Logic Analyzer, so the must be entered. The establishes the maximum measurement Span for the VSA as follows:
(real data)
Maximum Span = Sample Rate / 2.56
(complex data)
Maximum Span = Sample Rate / 1.28
The may be set to a value lower than the maximum value. The software filters and resamples the incoming data to reduce the span.
Whenever the or Center properties are changed, the of the measurement is reset to the new maximum value and the Center Frequency is set to equal the property.
The property is the same for all channels. Setting the value for any channel sets the same value on all other channels.
