13.3.3.3 Custom

Perform the following procedure to configure Custom Gating Mode:
1. The first requirement is that the PI-MAX4: 1024i-RF camera be aligned and focused on
the area of interest in the experiment. This is best accomplished while the camera is
operating in Full Frame readout mode. Verify that the
appropriate to the phosphor used by the camera: the phosphor decay delay time entered
in LightField can be viewed or changed after clicking on the Advanced button on the
Common Acquisition Settings
in
2. After the alignment and focus, the PI-MAX: 1024i-RF system needs to be put into RF
modulation mode. Configure the following parameters on the

NOTE:
The Phosphor Decay Delay setting is used to tell LightField
how long to wait after the gate pulse to shift the image. If there
is some residual image from the first frame in the second
frame, simply increase the Phosphor Decay Delay setting to
allow more time for the phosphor emission to decay before
shifting the image.
