What tools can be used to measure pulses and pulse width modulation
Thread Content
I have a GF 9900 controller on hand, which has two functions: proportional pulse generation and pulse width modulation. But what tools can I use to measure these functions? I only have a multimeter available. Please advise
Are you trying to measure the duty cycle? :o
To test the performance of this device, pulse width modulation, or duty cycle, I wonder what instruments can be used for that purpose
An oscilloscope certainly works for this purpose. Some multimeters have a duty cycle measurement function, but based on what’s shown on the display in your image, it seems that this device does not have such a function
I’ve never used an oscilloscope; I remember my teacher bringing in something that looked like a small TV when I was in junior high school
Use a Fluke 17B multimeter to measure the duty cycle.
What is the purpose of measuring the duty cycle? Can the average voltage measured under the same load conditions be used to estimate Ha?
Find a more advanced Fluke model. Finish the job
