Absolutely FREE! Signal Generator Features

Automotive Crank Sensor Simulator uses free signal generator for testing Engine Control Unit.

FFT Filter Mini-App demonstrates the use of a Custom Controls dialog, Multitasking Macro, and Macro Arrays to create a "brick wall" filter and apply it to various signals.

Lissajous Mini-App uses Macro Arrays and Multitasking to display two signals plotted against each other in X vs Y mode.

Phase Meter Mini-App allows precision measurement of the phase difference between two equal-frequency sine waves.

Speech spectrograms show individual syllables, glottal pulses, harmonics, etc.

Pitch Tracker shows instantaneous pitch of whistled "Deck The Halls" song, with 'piano keyboard' background.

Pitch-to-MIDI operation, also used for DaqMusic and KaleidoSynth (below).

Floating resizeable Voltmeter, with True RMS, Pk-Pk, Pos/Neg peaks, dB, dB Ref, Continuous Peak Hold, adjustable decimal places and time constant.

Floating resizeable Sound Level Meter, with Weighting and Response control dialogs, Continuous Peak Hold, and adjustable decimal places.

	Floating resizeable Frequency Counter, with Fast/Slow update rates, high-resolution Hertz, RPM, and msec modes with Min/Max track/review, Total, SpecTot, and adjustable decimal places.
	Fcal option allows voltage-to-frequency sensor readout. Supports nonlinear sensor response via calibration tables. One-button unit conversion between Celsius and Fahrenheit. Circuits included for temperature sensor, DC voltage, and thermocouple. Fcal also supports prescaler circuit to read MHz frequencies.
