ORACQ PRM CAM CONTROL DURING READOUT Vertical Sync from Camera The Vertical Sync event indicates a vertical sync has been detected Note that this does not necessarily mean the image will be captured For instance if you have a free running camera at 30 fps with external trigger enabled you will get 30 events per second even though the X64 Xcelera AN LX1 QUAD waits for an external trigger to actually capture the next image This allows the application program to independently count frames coming from the camera The Sapera event value is CORACQ VAL EVENT TYPE VERTICAL SYNC 48 e Theory of Operation X64 Xcelera AN LX1 User s Manual Horizontal Sync Lock Unlock The Horizontal Sync Lock Unlock event indicates the state of the Analog to Digital Converter PLL with respect to the incoming horizontal sync In order to digitize accurately the PLL must be synchronized that is be locked to the incoming video HS This interrupt is available when video 15 connected to the X64 Xcelera AN LX1 QUAD whether it 1s acquiring images or not In addition a corresponding status flag can be read from the acquisition module Typically the application first verifies the HS lock condition before starting an acquisition sequence The Sapera event values are CORACQ VAL EVENT TYPE HSYNC LOCK and CORACQ VAL EVENT TYPE HSYNC UNLOCK The Sapera status values are CORACQ VAL SIGNAL HSYNC LOCK and CORACQ VAL SIGNAL HSYNC UNLOCK Data Overflow The Data
