Chapter 4 PC Operation - Tutorial
4.1 Introduction
The following brief tutorial guides the user through a typical series of actions and
parameter adjustments performed using the PC based APT software. It assumes that
the unit is electrically connected as shown in Section 3.7.4. and that the APT Software
is already installed - see Section 3.6. It also assumes that a piezo-actuated stage is
connected to the ‘STAGE’ connector on the rear panel.
4.2 Using the APT User Utility
The APT User.exe application allows the user to interact with any number of APT
hardware control units connected to the PC USB Bus (or simulated via the APTConfig
utility). This program allows multiple graphical instrument panels to be displayed so
that multiple APT units can be controlled. All basic operating parameters can be set
through this program, and all basic operations (such as piezo moves) can be initiated.
Hardware configurations and parameter settings can be saved to a file, which
simplifies system set up whenever APTUser is run up.
This tutorial shows how the APTUser application provides all of the functionality
necessary to operate the APT hardware.
1) Install the hardware as detailed in Chapter 3.
2) Switch ON the controller.
3) Run the APT User program - Start/All Programs/Thorlabs/APT User/APT User.
The APT server registers automatically the units connected on the USB bus and
displays the associated GUI panels as shown in Fig. 4.1.
Warning
Piezo actuators are driven by high voltages. Voltages up to 150V may be present
at the STAGE connector on the rear panel. This is hazardous and can cause
serious injury. Appropriate care should be taken when using this device.
Persons using the device must understand the hazards associated with
using high voltages and the steps necessary to avoid risk of electrical
shock.
The piezo controller must be switched OFF before the stage is plugged in
or unplugged. Failure to switch the controller off may result in damage to
either the controller, the stage or both.
