Chapter 10: Advanced Topics
Previous chapters discussed the configuration of hardware and software for basic
operation. This chapter discusses the following topics associated with experiment
synchronization:
• Shutter Control Modes;
• Trigger Response Modes;
• Output Signal Control.
NOTE:
Configuration parameters discussed in this section are
found on the following expanders:
• Shutter;
• Trigger In;
• Trigger Out.
10.1 Shutter Control Modes
Shutter Control mode is configured on the Shutter expander.
Available operating modes are:
• Normal;
In this mode, the shutter opens during exposure and then closes.
• Always Closed;
When selected, the shutter will not operate during the experiment and remains
in the closed position. This option is useful when making dark charge
measurements.
• Always Open;
When selected, the shutter will not operate during the experiment and remains
in the open position.
• Open Before Trigger
In this mode, the shutter is opened before an external trigger is received.
NOTE:
When using Expose During Readout, neither Normal mode
nor Open Before Trigger mode is available.
