change clock trigger value, output delay from trigger, output delay from pulse width, output
rise and fall times, and output high and low values.
When only two co-ordinate pairs are used, the oscillator outputs a linear variation of the pulse
with respect to the control input. When the number of co-ordinate pairs is greater than two,
the output is piecewise linear.
1.26 Magnetic Flux Source
This device is used with a Hall Effect Sensor.
The Magnetic Flux Source uses the “B” key to change the density and polarity of the
magnetic flux impacting on a Hall Effect Sensor. You must specify the sphere of influence of
the magnetic flux source by entering an integer value in the Magnetic Channel field in the
Value tab of the component’s properties screen.
The Magnetic Channel field on the Hall Effect Sensor must have a matching integer value for
that sensor to be influenced by the source. No two magnetic flux sources or generators should
have the same integer value in the Magnetic Channel field. You can have as many Hall Effect
Sensors as you wish to react to any given source/generator and as many different sources/
generators as desired as long as each source/generator has a different integer value.
1.27 Magnetic Flux Generator
This device is used with a Hall Effect Sensor.
The Magnetic Flux Generator produces a continuous varying magnetic field (sinusoidal with
N and S peaks). You can define the flux density, rate of rotation (translating to frequency) and
specify the sphere of influence of the generator by putting a unique integer value in the
Magnetic Channel field in the Value tab of the source’s properties screen.
