has been detected, and automatically readjusts the position of the Post Trigger slider.

The end-user can set the Post Trigger value by:

Click on the down-arrow, to the right of the entry window, and select one of the preset

values from the pull down list box, or

Enter a post trigger value, between the minimum and maximum preset values

displayed in the pull down list box, and depress the enter key.

Frames:

This field indicates how many images or frames will be recorded within the camera's

recording Duration time. This field will change based on the amount of memory in the

camera, and how the resolution, and sample rate are set, and will change accordingly.

Duration:

This field indicates the total length of recording time. The recording duration is based on the

amount of memory in the camera, along with the resolution and sample rate settings. This

field will change based on these variables. This field should be referred to when determining

the required number of Post Trigger frames to set.

Advanced Settings Selector

The Advance Settings fields are used to define End of recording actions, frame synchronization

clock parameters, Real Time Out parameters, camera clock, temperature thresholds, and signal

acquisition parameters, and more.

The following is a brief description of the setup parameters associated with the Advanced

Settings:

Cine Advanced

Exposure in PIV Mode

This feature has been designed for use in PIV (Particle Imaging Velocimetry)

applications. When enabled the Phantom v-series cameras are instructed to reduce the

Frame Straddle Time to an interval of 1.5µs. For a Phantom v710, v640, v310, v210 or

v12 the Frame Straddle time will be reduced to 300 nano-seconds

Trigger Delay

This feature allows end-users to add a delay between the trigger command,(via Phantom

Camera Control application, or hardware), and the actual recording into the camera's

image buffer DRAM. After the trigger signal is detected, the Phantom camera will

loop-record into DRAM the specified number of frames. The effect of this is a delay,

because the frames that will actually be kept into the camera's image buffer will be the

images recorded after this delay.

NOTE

Using Trigger Delay will automatically set Post Trigger position to the maximum.

CineMag

Direct recording to CineMag Enable Box

By default Phantom cameras will write the image data into its' DRAM image buffer prior to

writing it into the non-volatile Flash memory of a Phantom CineMag. When enabled,

(checked), the Direct recording to CineMag feature (called Run/Stop mode too) instructs

the Phantom camera to write the image data directly into the non-volatile Flash memory

of the mounted Phantom CineMag. The camera memory will retain in this case only the
