Event Detectors
105/106 Series
-
The 105/106 Series Event Detectors are the most versatile Event Detectors in the product line. These Event Detectors monitor the electrical resistance of up to 128 simple continuity loops, each comprised of single or multiple specimens under test. Each test specimen is continuously monitored while a selectable DC sense current is passed through each channel test-loop; resistance changes exceeding the selected threshold are recorded as an event. Minimum Event Duration, Channel Current, and Threshold Voltage settings can all be independently configured. 105 and 106 Series instruments are electrically identical, with the difference simply that the 105 offers four, 32-channel board slots and the 106 offers only one. Thus the 128-105 is equivalent to four 32-106 Event Detectors.

Composite 1×24 Video Distribution Amplifier
VDA124RM-12
-
Video Distribution Amplifiers (sometimes called a video splitter – not to be confused with a video split screen controller such as our PXD510E split screen controller) are typically used for connecting a camera or other video source to several monitors that do not have “looping” inputs. In this situation, each monitor has a permanent 75 ohm termination. With two non-looping monitors connected together, the line would be double loaded and result in a dim picture on each monitor. Using a Video Distribution Amplifier will solve this problem by driving each monitor individually at 100%.
