Waveform Analysis (Parametric)
Overview
This section describes the parametric measurement by waveform analysis. Waveform
analysis is performed by an oscilloscope. If an oscilloscope is not installed in your system,
this measurement can not be executed.

Specifies the speed at which data bits are
written on the media per second [bps].
Specifies the current applied to the write head.
Specifies the current applied to the read head.
Specifies the sampling rate of the
oscilloscope. The sampling rate of the
oscilloscope is specified by the (channel bit
rate) x (oversample rate).
Specifies the data pattern to be written on the
test track. To set the data pattern, click on the
[Configuration] > [Setup] > [Pattern Config]
buttons to open the data pattern menu.
Specifies the track number to be tested.
Specifies the number of revolutions to get the
average results.
Specifies the type of measurement sequence.
