Bank Control (Modal Locations)Panel
Note: This option is only effective when the averaging mode is used.
Auto Bank Increase
with Automatic
Saving Data: A Bank is a set of response channels. You can have eZ-Analyst
increment the banks automatically after each measurement, or
you can manually increment the banks. The number of active
channels is used as the skip factor for bank switching.
If the Auto Bank Increase checkbox is checked, then the bank is
automatically incremented, but only when the automatic saving
data option is selected at Setup Export Function Data menu.
Response Increase: If the Response Increase radio-button is selected, the reference
channel’s location doesn’t change. The response’s location(s) are
increased [or decreased] for next available location numbers.
Reference Increase: If the Reference Increase radio-button is selected, the response
channel’s location doesn’t change. The reference’s location(s) are
increased [or decreased] for next available location numbers.
Location Increment: Indicates the number by which eZ-Analyst is to increment the
response or reference location after each measurement.
Note: Decreasing location numbers are only available with the manual bank
button on the Modal Locations window. Modal Locations is accessed from the
Windows pull-down menu.
A Note About Channel Pairs
A Channel Pair is a Reference channel and a Response channel that are used to display a dual-
channel function, such as an FRF (Frequency Response Function). Channel Pairs are
automatically defined when a user selects "Reference" channel type for an input channel. For
example, if Channels 1 and 2 were defined as reference channels, then all response channels
would paired to those channels. Thus,
1,1
2,1 3,1 4,1 5,1 6,1 7,1 8,1 and
1,2 2,2 3,2 4,2 5,2 6,2 7,2 8,2
To export all of the data for the Channel Pairs, select the “All Ch. Pairs” radio button in the
Export Function Data window (see chapter 3 for window details).
