Here is a list of helpful things you might want to know:. Now we’re ready to proceed to real-time continuous systems. What’s happening just as you increase the drive frequency but before the plot becomes jittery? Moreover, you should think about a policy of choosing a proper target folder for the binaries created. A “bundle” is a LabView data-structure that is a convenient way of collecting several things into one.

Note that, due to the oscillations of the cantilever, the frequency shift approach experiences snap down sooner than the DC level approach. Vary it between and 10, Hz. Using a function generator Stanford Research Systems Model DSadjust its output to produce an approximately Hz sine wave, 5 Volts in amplitude 10V peak-to-peak. Now we’re ready to proceed to real-time continuous systems.

Stanford Research DS345 Signal Generator

Your first assignment is to make a simple VI. Outside the loop, the arrays are “bundled” into a form that the XY-graph module will accept: Approach and retract curves are shown, demonstrating snap-down and off.

What happens if the sample rate is a multiple of the frequency of the cosine? Panel b shows a the line-cut indicated by white dashes in awhile d represents the line-cut from c.

After you look at the algorithm in Ref. Again, try to do this on your own. Sensitive dependence on initial conditions is one of the defining features da345 chaotic behavior.


When a is zero, it’s a two-dimensional uncoupled harmonic oscillator and its trajectories are confined to a torus in phase space c.

Be sure to look at quad. Try to come up with one of your own. What effect does changing the sample rate have on the shape of the trajectory?

If you find yourself spending more than an labviiew or so xs345 it, you should look at the solution in the appendix.

Connecting the scope to see the phase portrait of the PN-junction. Both circuits, as well as most of the supporting electronics are located behind the large panel marked “Nonlinear Dynamics Laboratory. LabView is a graphical programming environment designed to facilitate lab-instrument control, data-acquisition, and rudimentary numerical analysis.

Next, expand the “Build array” icon to three inputs and start the cobweb part. Experiment and Procedure III. For example you can wire an array and a constant to the “add” function and the result is a new array whose elements are the old array with the constant added to each of them.

We’ll discuss these options later. Close the build specification by pressing “OK”. See the article by Theiler for full details and Ref.

It is simple to add procedures, data collection and manipulations, etc. We’ve already written a VI, named quad. Calculate, or look-up in a reference, the Fourier series of a triangle wave.


Read what these modules do, and then make a block diagram on paper illustrating how you would use ds435 functions to make the necessary x and y arrays for the cobweb. See if you can explain what’s happening. Then get the wire tool and wire up the Array input to the output of the AI Wave.

The phase-portrait becomes jittery and then it should jump to behavior that is periodic at twice the drive frequency. We stress that it’s the discrete transform because, while it is closely related to the continuous Fourier transform, there are some important differences that we hope you’ll discover.

The scan settings include the origin; scan size, resolution, angle rotation ds3345 fast and slow axes with respect to the piezo tube x and y axesand rate; slope correction controls; choice of imaging variable; and estimated scan time indicator. As you experiment with the parameters of the exercise, you may want to change the range of the graphed data.

The bouncing ball circuit and the PN-junction.
