Generating Waveform
The magnetic disk reading waveform is generated based on the input data, isolated
pulse, and superpose parameters. To generate a waveform, select Superpose
(bottom)!Execute (side).
The square pattern with the period of one cell is set in Marker 1. The input data is
set in Marker 2.
Isolated pattern is calculated for only 20 cells, and the other part is considered to
be 0.
For the isolated pulse, wraparound is included in the calculation in superposition,
assuming that this waveform repeats. However, the calculation is not made for the
second and subsequent cycles of wraparound. Therefore, the correct calculation is
not made for input data shorter than the isolated pulse length (20 cells).
The NLTS calculation requires the position of the previous pulse, which cannot be
obtained from the initial part of input data. Also for this problem, information is
obtained with wraparound by using the last part of input data.
Saving to File
You can save the generated waveform to a file. If the waveform length does not
satisfy the instrument file length conventions, the instrument repeats the data
several times and regenerates the waveform to create a valid file.
NOTE. One restriction is applied to the number of input data points;
input data points > isolated puls data points / (Samples/Cell)
