Works like it should within limits Checked it on the Rigol 1052e also with FFT. The sine waves are ~ flat ~ 20Hz-17kHz ; frequency is stable then drops quickly. Some waveforms generate small spurs 3-4x the fundamental about - 30dB. The triangle wave distorts above 1kHz and the square has a lot of ringing. Other functions work as expected within the above limitations and the constraints of the menu items [ e.g. sweep rate or modulation %]. It can be recommended as a pocket signal generator for gross testing whenever you need an audio signal such as troubleshooting speakers, headphones or testing gross frequency response. The menu system is workable but crude, no bugs immediately noticeable. The triangle & square waveforms are of limited usefulness due to distortion. Generated using a Droid 2 on a 100 ohm resistive load to emulate headphones.

Good. Good duty cycle slider doesn't do anything though niether does amplitude bar.

TESTED IN MY LAB... DONE WITH MY TEK 200MHz OSCILLOSCOPE, WITH A 100 OHM LOAD ON PHONE OUTS... I AM USING A NEXUS7 32G TABLET. 1. GREAT SIGNALS, SINE VERY CLEAN ALL THE WAY, TRANGLE AND SQUARE DEPEND ON SAMPLING RATE. FINE UP TO 6KHZ, THEN THEY ROUND OFF. LOGICAL. 2. LIKE THE LOG SWEEP OPTION AND OTHERS, LOVE TO DO LONG SWEEPS TO CHECK STANDING ROOM WAVES. 3. Wish the keyboard did not pop up all the time... 4. Wish it did not revert to 440 Hz every time BUT KEPT MY LAST SETTING. Otherwise, CLEAN, VERY LITTLE JITTER, GOOD DESIGN, THE BEST FREE OUT THERE ! KEEP IT UP GUYS, blessings from Caracas.
★★☆☆☆
Actual waveforms are poor Observed on a scope - square wave definitely does not even resemble a square wave. Sinewave not evenly biased and negative peaks dampened on one channel.? But deserves an extra star cause its free.

Froze my HTC desire. Needs more work.

Total crap Doesn't work on my LG lucid 2 every time I press a button I says that it stopped working Uninstalling
