Phantom Help File94

First

Firsts defines the image number of the first cine image to be used to create the cine

file to be saved or viewed.

Count

Count defines the total number of cine images used to create the cine file to be

saved or viewed, starting from the First image defined above.

External Sync

The External Sync parameters, listed below, are used to define the frame sync clock source,

specify the master camera supplying the frame sync clock source to other Phantom cameras,

and define how much to delay the recording of image data from the frame sync clock pulse.

The External Sync parameters include the:

Sync Imaging (Selection List Window)

This entry field instructs the selected camera to utilize one of the following three frame sync

clock sources:

Internal

This mode instructs the camera to utilize its' internal crystal oscillator to drive the

camera's sample rate.

External

This mode should be selected when an externally supplied frame sync clock pulse is

supplied to drive the camera’s sample rate. The external input must be a TTL pulse, with

a frequency up to the maximum sample rate. (Example: 1000Hz @ 512 x 512 resolution,

2000Hz @ 256 x 512 resolution.) The TTL input pulse must be connected to the BNC,

(Bayonet Neill-Concelman), connector marked Sync on the Capture breakout-cable/box.

NOTE

When External sync imaging is selected the Sample Rate option will be disabled.

Lock to IRIG

This mode should be selected when an IRIG-B signal is supplied through the marked

IRIG Input BNC, (Bayonet Neill-Concelman), connector on the Capture breakout-cable/

box.

NOTE

When Lock to IRIG sync imaging is selected the Sample Rate option will be disabled.

Refer to the Functional Descriptions>Frame Rate Tables for a list of frame rates a

Phantom camera will lock to.

Master camera serial (0=none)

The Master camera serial parameter specifies the serial number of Phantom camera

providing the frame sync clock source. If set to zero, (0), no external sync will be applied.

This field MUST be defined when synchronizing multiple Phantom cameras using one

Phantom camera as the primary clock source.

Frame Delay µs

The Frame Delay parameter field can be used in one of two ways:
