'External Sync' instructs the camera to use one of the following options:
•
Internal: Camera uses its internal crystal oscillator to drive the frame rate.
•
External: Camera uses externally supplied frame sync clock pulse to drive the
frame rate. This can be used to synchronize two cameras together via F-Sync.
•
IRIG: Camera uses an IRIG-B signal is supplied to drive the frame rate.
•
Lock to Video: Frame rate is driven by the camera's current video rate. Fps will
jump to the closest multiple of the current video rate (23.98, 24, 25, 29.97 or 30).
•
Sync to Trigger: Instructs the camera to adjust its frame clock, upon detection of
a trigger signal, to ensure all post trigger frames occur at the same moment in
time from trigger when repetitive tests are required.
When using External Sync it is important to limit the top frame rate by ~1%
to ensure the sync period is larger than 1/max_frame_rate + 0.1% or 200ns
(whichever is larger), to account for frequency tolerance and jitter.
FL A SH MEMORY
Specifies the camera's operation mode in relation to CineMag
recording: 'Loop' (record to RAM first) or 'R/S' (bypass RAM
and record directly to CineMag). It also displays the amount of
free space and size (in Gigabytes) of the Phantom CineMag.
RECORDING A CINE
To begin recording to the camera's RAM click the red 'Capture'
button.
The red 'Capture' button changes to 'Abort Recording' and the
green 'Trigger' button is enabled when the camera is recording.
The 'Abort Recording' button instructs the camera to stop
recording, leaving the camera's RAM empty.
TRIGGERING THE CAMER A
Selecting the 'Trigger' button instructs the camera to immediately stop recording when
the 'Trigger Position' is set to zero. If a value greater than zero is set, the camera will
continue to record 'post-trigger' frames until the user-specified value is met.
Using the camera's external trigger signal provides a more accurate trigger
to the camera. This is also referred to as a 'hardware trigger.'

RE VIE WING A CINE
Once the camera has completed recording a Cine in
the camera's RAM or CineMag, it can be reviewed by
selecting it from the 'Cine' pull-down selection list in the
PCC 'Play' tab.
A previously saved Cine stored on the computer's hard
drive can be opened using the 'Open File'
button. (When used, it also places the file under the
'Cines' group folder in the 'Manager' tab.)

PERFORMING A QUICK SE ARCH THROUGH A CINE
Quickly find the points of interest:
'Scroll' (scrub) through the clip using the slider or click
anywhere on the timeline to jump to that point quickly.
'Jump' to the trigger frame by clicking on the 'T' button,
or jump to specific frames by entering the frame number
into the jump '#' data entry field, then hit the enter key.
'Image Search.' The goal is to search or find an image
change in the recording, based on the differences
between image content. Right-click on the 'Play' button
to begin the image search. Besides image content changes,
'Image Search' can also look for images that are tagged
as 'Event' images.
