406 WM-OM-E Rev I
pw50+ Pulse Width 50+
Definition The average pulse width at the 50% point between the local feature
baseline and the local feature peak.
Description All local features between the parameter cursors for an input waveform
are identified. The local baseline is identified for each feature, and the
height between the local baseline and peak is determined. The pulse
width is measured at 50% of the peak amplitude. The average of all width
measurements is displayed as pw50+. Provided for histograms is the
average pw50+ value for each local feature between the parameter
cursors.
Parameter Settings Selecting this parameter displays a hysteresis-dialog for setting the
hysteresis value to a specified number of vertical divisions.
res Resolution
Definition The ratio of the track average amplitude for a high and low frequency
waveform.
Description res returns, as a percentage, the ratio of track average amplitude (see taa
parameter description) for a low frequency LF and high frequency HF
waveform:
res = (taa(LF) / taa(HF)) * 100%.
Parameter Settings Selecting this parameter displays a hysteresis-dialog for setting the
hysteresis value to a specified number of vertical divisions.
taa Track Average Amplitude
Definition The average peak-to-trough amplitude for all local features.
Description All local features between the parameter cursors for an input waveform
are identified. The peak-to-trough amplitude is determined for each
feature, and the average is returned as taa. Provided for histograms is the
peak-to-trough amplitude for each local feature between the parameter
cursors.
Parameter Settings Selecting this parameter displays a hysteresis-dialog for setting the
hysteresis value to a specified number of vertical divisions.
taa- Track Average Amplitude-
Definition The average local baseline-to-trough amplitude for all local features.
