Userdefined function in waveform

[Yasir-z]

Hi everyone,

I dont have an electronics background so my question might sound too simple. I need to drive some piezoelectric actuators with a signal using a Signal Generator or WaveForm software (and Analog Discovery 2). The signal has to be a constant voltage signal, eg 5 volts at some frequency like 1Hz. However, it should not be a step signal but initialy a ramp signal for a short time and then just a constant voltage for the total duration, e.g 60seconds. I just don't know how to create such a signal using something like WaveForm. 

Would appreciate any help. 

Thank you.

Hi @Yasir-z

You could use DC voltage since offset on enable/disable has a few ms settle time, a ramp-up/down.

I don't understand what do you mean by "constant voltage and frequency"

Hi Attila,

Thank you very much for the reply. I have been trying to replicate what you have shown but still cant get the ramp up curve on the Scope when i verify it. I just see a straight line. You can see the images below. What am i doing wrong? For the case of a simple sign wave  i do see the correct response in Scope.

Hi @Yasir-z

Toggle the Enable checkbox in the Wavegen after the Run/Stop button.
