Actually i have a bimorph piezoelectric material (piezo-film deposited in Stainless steel substrate), and based on simulation the resonant frequency is around 20Hz.

I'm sorry i didn't tell the whole story. So first i have experiment in piezoelectric material. I will apply AC voltage (using pulse generator) and then i will measure the output voltage using oscilloscope. From that i need to determine the resonant frequency, by sweeping the frequency. When i...

So First, your saying using "External Width Mode" we can program the frequency, but we need an external sweep generator? (can you provide brand and model?). Second, if we set the frequency in 2Hz, based on my experiment the generated voltage is not stable (range from 20mV-10mV), but as your...

May you suggest an external trigger (brand and model, the cheapest one) that works in my pulse generator?

The parameter that i used are: Amplitude voltage = 5V, delay =0.0ns, Resistance = 50 ohms, cycle =50% and frequency = 1 to 100 with an 0.1 interval and have 2 seconds delay. Thank you very much for your help!

My problem is, how to vary the frequency automatically.

Hi there! is anyone here working with a pulse generator? I have Agilent 8114A Pulse generator i want to vary the frequency automatically like 1.1Hz to 10.1Hz with 1-2 secs delay. This pulse generator have a HP-IB bus at the back that can connect in a PC. Base on the Manual it can program using...

This one sir?

So this is the set-up your trying to say? if i set the resonant frequency i will detect higher amplitude voltage?

Is CRO a special type of oscilloscope?

No sir, i vary the frequency manually (from 1-100hz because the simulation results fall at 50hz). I will take note your suggestion but i need to plot voltage vs. frequency.

yes sir!

Yes sir you're right! basically another way is to measure the current across the piezoelectric material as the frequency varies. But i need to plot the voltage vs. frequency. So using oscilloscope i can determine the voltage amplitude due to vibration, But then as i said no change in voltage...

So i have a piezoelectric film deposited in the metal substrate and i want to determine the resonant frequency. Basically i can determine the resonant frequency base on the dimensions. But i need to proved it using experimental set-up. So i applied AC Voltage to the material then the material...

when a piezoelectric material experience a stress it generates voltage, and also when you applied voltage the piezo-material experience a vibrational frequency. Using oscilloscope we can determine the induced frequency of the piezo-material with respect to the applied voltage. Now given the...
