How do you connect a piezo to a frequency amplifier/generator?

I need to know a how a piezo can be connected to a frequency amplifier / generator so that I can make the piezo move linearly and vary the frequency of the piezo and some readings can be taken. Please tell me how this can be done exactly.

How would a piezo that has three leads coming out of it connect to a frequency amplifier?

How would a piezo that has two leads coming out of it connect to a frequency amplifier?

You generally need a power amplifier that has a very high compliance voltage output (100s of volts) and is stable for very high capacitance loads.

Example: Apex brand (now under Cirrus Logic) PA-89, or PA-90

The 3rd lead from the transducer is usually the case-ground.
