The outputs of the kits are two square waves in quadrature with a third channel that offers a 90-electrical-degree, true index pulse that is generated once for each full rotation of the code wheel.
Proposed behavioral model is obviously not suitable for high frequency operation with large signal levels (it reaches supply saturation corners in our case--see square waves in the graph), due to existence of high impedance node with large parasitic capacitance (frequency dependent impedance) of node of [V.
Rise times are important for studying square waves and pulses.
The WaveXciter provides separate or synchronized channels with 10-ps resolution, 1-GHz sine and 500-MHz square waves, and 16-M (32-M optional) waveform memory.
Square waves have shown the greatest effect on microorganisms since they operate at a maximum voltage for the duration of the pulse, whereas exponentially decaying pulses only retain the maximum voltage for a very short time.
An on-chip DC-DC step-up converter and 4 half bridge drivers to create pairs of phase-shifted square waves with ultrasonic frequency to drive the SQUIGGLE micro motors.
The switches are driven with square waves of current or voltage, and by adjusting the frequency around the resonant point, the voltage on the resonant components can be controlled to any practical voltage level.
This instrument includes a true differential digital multimeter, a counter/timer, a function generator for sourcing DC, sine and square waves, and digital I/O bits for logic sourcing, sensing and controlling external hardware and relays along with standard GPIB (IEEE-488) and USB 2.
It has the ability to drive heavy loads and to replicate even square waves because of its high slew rate.
Standard waveforms such as sine, triangle, and square waves are easily produced by loading the output memory and triggering them synchronously or separately.
