* Introduction :ignore:
|
||
|
|
The goal of this test bench is to characterize the Voltage amplifier [[https://www.piezodrive.com/drivers/pd200-60-watt-voltage-amplifier/][PD200]] from PiezoDrive.
|
||
|
|
|
||
|
|
* Voltage Amplifier Model
|
||
|
|
The Amplifier is characterized by its dynamics from voltage inputs $V_{in}$ to voltage output $V_{out}$.
|
||
|
|
Ideally, the gain from $V_{in}$ to $V_{out}$ is constant over a wide frequency band with very small phase drop.
|
||
|
|
|
||
|
|
It is also characterized by its input noise $n$.
|
||
|
|
This noise is described by its Power Spectral Density.

* Transfer Function measurement
|
||
|
|
|
||
|
|
In order to measure the transfer function from the input voltage $V_{in}$ to the output voltage $V_{out}$, the test bench shown in Figure [[fig:setup-dynamics-measurement]] is used.
