Video Cross Line Generator
CL5410
-
The CL5410 can generate up to 4 lines at once and each line may be on a horizontal or vertical axis. This allows the CL5410 to replace the CL5400C, CL5404C and CL5405C and retain all of the functionality of each unit and more. The CL5410 is built on a new platform and allows a wide variety of options to be selected in the menu system. However, even with the enhanced menus, the CL5410 still has the same legendary ease of use like our previous models. That means enough buttons to change commonly used setting easily without the hassle of a menu..
