Hi,
I have a system setup with a piezo actuator and amplifier, a accelerometer and power supply attached to a cantilever beam and NI USB-6251. The aim for the setup is to see how different frequencies generated by the actuator effects the cantilever and what input the accelerometer detect for a given frequency/amplitude. My problem is that it seams clear that the waveform generated is affected by the timing settings. For instance will the actuator produce two different frequencies when I change the sample rate for the system. This is validated both by the accelerometer and notable change in pitch (sound from when the system is running). I've used the Voltage - Continuous Output.vi and simultaneously augured signal from the accelerometer. Why is that so?
Why do sample rate affect piezo actuator

Hi Jordan,
I've tested the system with a sample rate between 1000-4000 and a frequencies mainly between 100-300Hz, 600Hz at the most.
