Chapter 5 TRIGGERING TYPES & CAPTURING METHODS 5.1 Triggering the LBA-PC The LBA-PC can support four basic types of triggering: • CW (or no trigger required), for lasers whose light output is continuous or pulsed at such a rate as to appear continuous to a camera (typically faster than 1000 Hz)....

For example: If you are using an LBA-712PC frame grabber (a 12 bit digitizer) you have the following possible Video Trigger Level choices: 256, 512, 1024, 2048. If you set the level to 512, the LBA will capture a laser ...

Example: With the Capture Interval set to 10, and a 30 Hz frame rate camera, the capture rate will be 3 fps. 5.2.1.2 With Trigger Type set to Trigger Out The frame rate of the camera and the Trigger and Capture Intervals will combine to determine the capture rate. Example: With the Capture Interval ...

Note: Do not confuse this type of integration control with features on high-end digital cameras that have externally programmable integration controls. These later types of cameras are programmed by issuing serial commands to the camera’s internal microprocessor. See section 5.4 for a discussion of ...

Operator’s Manual LBA-PC 216 A.3 LBA-PC Command and Data Formats The LBA-PC does not support the IEEE 488.2 specification of sending multiple commands separated by semicolons. Each command must be sent separately and terminated by asserting the EOI line with the last byte sent. The following are som...

B.3.1 Basic Results .vi This program shows the basic communication between LBA-PC and the local computer. It contains three buttons: “Run/Stop”, “Ultracal”, and “Auto Aper on/off” on the left side of the window. This VI shows all basic results on the right side. Basic Results Panel Figure 64 LabVIEW...

• Get Basic Results .vi These VIs are easy to understand if one has some experience in LabVIEW programming. The processing sequence is controlled by the “Error In” and “Error Out” connection chain. That means a function unit is processed earlier if it is closer to the starting “Error In” connection....
