Disk Standard Parameters
These parameters enable standard disk drive waveform parameter measurements. These
parameters are accessible by touching Measure in the menu bar, then touching the My Measure
button, and then a parameter button: P1 to P8.
DISK STANDARD PARAMETER DEFINITION
aasym
amplitude asymmetry between taa+ and taa-
p@lv
period of each cycle in an acquired waveform,
called Jitter in the parameter menu
nbph
narrow band phase of waveform Discrete Fourier
Transform (DFT)
nbpw
narrow band power of waveform Discrete Fourier
Transform (DFT)
owrt
overwrite
pw50
pulse width of peaks at 50% amplitude from
baseline
pw50+
pulse width of positive peaks at 50% amplitude
from baseline
pw50
pulse width of negative peaks at 50% amplitude
from baseline
res
resolution
taa
track average amplitude
taa+
track average amplitude of positive peaks from
baseline
taa
track average amplitude of negative peaks from
baseline
All disk standard parameters except nbph, nbpw, owrt and p@lv make their measurements on
waveform peak-trough pairs. In addition, several of the parameters determine the baseline of
peak-trough pairs in order to perform their calculations.
Note: The DDAs variable hysteresis setting is essential for identifying peak-trough pairs.
