11.1 Setup and Operation
The PI-MAX4 must have an installed MCP Gating board.
• Make all of the required cable connections for the experiment.
• Apply power to the equipment and launch the application software.
• Configure the gating parameters. Start with a relatively long gate to acquire the
phenomenon of interest.
• Begin running the experiment.
• Finally, narrow down the gate to the desired operation.
NOTE:
Pulse repetition rate is limited to 8 kHz.
