Spacing
Press <SELECT> to control the spacing between collected spectra or between Phase/
Magnitude/Speed/Acceleration points.
z
Speed-Linear - Collects data with uniform spacing between the two specified speed
limits.
z
Speed-Log - Collects data with logarithmic spacing between the two specified speed
limits. More data is collected at lower machine speeds than at higher machine speeds.
z
Time - Enables you to specify that data be collected on uniform time intervals (data is
collected only if the machine speed has changed since the last data set for triggered data
collection). The time interval has a tenth-of-a-second resolution.
z
Manual - Enables you to control when data is to be collected based on pressing
<STORE>.
Frequency Max
Press <SELECT> while in this box to display a list of maximum frequencies to use during
measurement. Use the arrow keys to select an item in the list, and press <SELECT>.
Low Freq Corner
Press <SELECT> while in this box to define the frequency below which the input signal is
significantly attenuated. This selection may affect the time required for the input signal to
settle. The lower the frequency, the longer the time required for the signal to settle. Select a
higher Low Frequency Corner, and the dataPAC ranges faster. Select a lower Low
Frequency Corner, and the dataPAC gives better low frequency data, but takes longer to get
it.
