11. Perform the following procedure to configure Gate Timing:
a. Open the SuperSYNCHRO Timing expander located just above the Status bar.
See Figure 9-14 .
Figure 9-14: Typical SuperSYNCHRO Timing Expander
b. Select Sequential as the Active Mode.
If you have a Gen II intensifier, set Bracket Pulsing to OFF for this experiment.
c. Define the pulse sequence as follows:
• Click on the Number of Frames hyperlink. Enter the number of frames to be
acquired. For this experiment, enter 41.
• Configure the Start Time and End Time for the Gate Width.
Since this experiment requires a fixed gate width, these values will be the
same.
• Configure the Start and End Durations for the Gate Delay.
For this experiment, the Start Delay is 1

s and the End Delay is 201

s.
• Click the On-CCD Accumulations hyperlink and enter the number of On
CCD Accumulations per frame. For this experiment, enter 1.
d. The SyncMASTER ON button allows you to enable the SyncMASTER™ trigger
output from the SyncMASTER1 and SyncMASTER2 connectors on the AUX I/O
cable and select the frequency for the SyncMASTER outputs. You can also set
up the AUX Output signal at the AUX OUT connector on the rear of the PI-MAX3.
•
When you enable SyncMASTER, the output of the SyncMASTER1 connector
will be at the frequency configured in the Internal Trigger Frequency field.
• The output of the SyncMASTER2 connector will be at the same frequency as
that of SyncMASTER1. However, you can enter a delay so the edges of that
signal will occur after the edges of SyncMASTER1.
• If you are using the AUX Output signal from the SuperSYNCHRO to trigger a
piece of equipment, configure the Auxiliary pulse delay time. Configure the
pulse width needed to trigger the equipment.
Figure 9-15 illustrates a typical SuperSYNCHRO Timing configuration with
SyncMASTER on.
