Absolutely FREE! 8-channel Signal Generator Features

[LCR Meter Thumb]
LCR Meter Mini-App allows precision measurement of inductors, capacitors, and resistors. Shows capacitor ESR, optional DF and Q.

[Engine Simulator Thumb]
Automotive Crank and Cam Sensor Simulator uses free signal generator for testing Engine Control Units.

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

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

[Speech Sgram1 Thumb] [Speech Sgram2 Thumb]
Speech spectrograms (voiceprints) show individual syllables, glottal pulses, harmonics, etc.

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

[Pitch-to-MIDI Thumb] Pitch-to-MIDI operation, also used for DaqMusiq and KaleidoSynth (below).

[DaqMusiq Thumb] DaqMusiq and KaleidoSynth

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

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

[Freq Counter Thumb] 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 Deg C Thumb] 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.
