Eye Width
Eye width is the measurement of eye width in seconds.
Eye Width = (tCross2Mean - 3 x pTopSigma) - (tCross1Mean + *tCross1Sigma)
Fall Time
This timing measurement is the time required for the falling edge of the first pulse in the
waveform or gated region to fall from the high reference value (default = 90%) to the low
reference value (default = 10%) of the final value.
Fast Acquisition
Force Trigger
Click this button to force the instrument to trigger and complete the current acquisition regardless
of whether any other trigger event occurs (if the acquisition is currently running). This has no
effect if the acquisition system is stopped.
Frame
A frame is a segment of the entire data record. When used with FastFrame, each segment contains
all the data of a single acquisition. Each captured event is stored sequentially in its own frame. The
frames are in the order they were captured.
Frequency
This timing measurement is a measure of the first cycle in a waveform or gated region. Frequency
is the reciprocal of the period; it is measured in Hertz (Hz) where one Hz is one cycle per second.
Frequency Span
The frequency span is the range of frequencies over which the spectral analysis is performed. The
maximum span is from DC to one half of the sample rate (the Nyquist frequency). A smaller
frequency span allows a greater range of center-frequency adjustment. If a larger frequency span is
desired, increase the sample rate.
