# Introduction
A test setup has been installed on the PSSS called PSSS larger bandwidth (LB).  The intended purpose of the setup is to:
1. Increase the spectral bandwidth measured by the PSSS
2. Increase the signal to noise ratio for weaker signals (few uJ, 3rd harmonic measurement etc)

The setup is a test and not easily operated by users

# Setup

Camera and screen move in X and Y together.  Screen moves in Z on separate stage.
