intersect, click the "Calc" button next to the End Frequency parameter that needs to be computed.
For example, to find the intersection between 0.002 in displacement and 0.6 in/s velocity:
1.
In the first segment, enter 0.002 for the Start Amplitude and select "in" for the units
2. Set the starting frequency (e.g. 30 Hz)
3. In the second segment, enter 0.6 for the End Amplitude and select "in/s" for the units.
4. Enter the second End Frequency (e.g. 200 Hz)
5. Click the "Calc" button next to the first End Frequency parameter. A dialog box will appear:
6. Click the "Yes" button to automatically select this frequency as the end frequency of the first
segment and to set the two lines to constant displacement and constant velocity, respectively.
The "Insert" and "Delete" buttons allow you to add and remove segments in the breakpoint table. The
currently selected segment (indicated by the small arrow on the left side of the dialog box) will be
deleted when the "Delete" button is pressed. Inserted segments will immediately follow the currently
selected segment.
At the bottom of the dialog box are the maximum acceleration, velocity and displacement requirements
for the test. These boxes will be highlighted in red if the test exceeds the
System Limits and in
yellow if the test is within 5% of the system limits.
The tabs along the top of the dialog box are used to select the following parameter entry screens:
Profile Enter the frequency and amplitude breakpoints.
Schedule Set test duration and amplitude scaling level.
Sweep Enter sine sweep rates
Parameters Enter control loop parameters.
Limits Enter the safety limits.
Channels Select tracking filters and active control channel.
Data Storage Select automatic data storage parameters.
Resonance Enable/disable the Resonance Search feature.
Extremal Enter Extremal (extreme conditions, AVD) parameters. (optional module)
Step Tests Enter sine step test parameters. (optional module)
The buttons at the bottom of the dialog box perform the following operations:
Save As... Save the current settings under a new test name.
OK Save the changes to this test and close the dialog box
Cancel Close the dialog box and abandon all changes
Apply
Apply the changes to the currently open test (does not save changes to the hard disk).
Help Get help information about these parameters.
