1. An automatic test system for testing a unit under test, comprising:
- a plurality of measurement devices, each of said devices providing an output signal representing a measurement by the device when conducting a test of the unit under test and the output signal including a video component, each of said devices lacking an associated display on which the video component of the output signal from said device can be displayed, each of said devices comprising a test instrument that generates the output signal including the video component, said test instruments being different from one another such that different measurements from tests conducted by said devices on the same unit under test are represented by the output signals from said devices, andan arrangement for enabling selective and real-time display of the video component of the output signals from said devices on a single display, said arrangement comprising;
a switching component having a plurality of inputs, each of said inputs receiving the output signal from a respective one of said devices, and a single output to the display; and
a controller for controlling said switching component to selectively connect only one of said inputs to said single output to enable conveyance of the output signal from said device providing the output signal to said selected input through said switching component to said output of said switching component and then to the display,said switching component and said controller being housed in a separate housing from the plurality of devices and from the display.

Abstract
Video selection display unit that is capable of routing real-time output signals having a video component from different video signal sources, e.g., different instruments or home entertainment devices, to a single output for display on a monitor or other type of video display. The video selection display unit may be part of an automatic test system or home entertainment system. Control of the video selection display unit can be effected locally via a user interface, such as one or more pushbuttons, and/or remotely over a network which may be the same network used for communication with the instruments or devices or using an infrared remote control unit.

17. An automatic test system for testing a unit under test, comprising:
-
a plurality of measurement devices, each of said devices providing output signals representing a measurement by the device when conducting a test of the unit under test and the output signal including a video component, each of said devices lacking an associated display on which the video component of the output signal from said device can be displayed, each of said devices comprising a test instrument that generates the output signal including the video component, said test instruments being different from one another such that different measurements from tests conducted by said devices on the same unit under test are represented by the output signals from said devices; a single video display for displaying the video component of the output signals from said devices in real-time; and a video selection display unit for enabling selective display of the video component of the output signals from said devices on said display, said video selection display unit comprising; a switching component having a plurality of inputs, each input receiving the output signals from a respective one of said devices, and a single output to said display; and a controller for controlling said switching component to selectively connect only one of said inputs to said single output to enable conveyance of the output signals from said one of said devices providing the output signals to the selected input through said switching component to said single output of said switching component and then to said display, said switching component and said controller being housed in a separate housing from the plurality of devices and from the display. - View Dependent Claims (18, 19, 20)

21. A method for managing video output in real-time from a plurality of measurement devices of an automatic test system for testing a unit under test that lack displays but provide output signals representing a measurement by the device when conducting a test of the unit under test and the output signals having a video component, each of the devices comprising a test instrument that generates the output signal including the video component, the test instruments being different from one another such that different measurements from tests conducted by the devices on the same unit under test are represented by the output signals from the devices;
- the method comprising;
connecting the output from each of the devices to a respective input of a switching component; connecting a single output of the switching component to a single video display; and controlling the switching component via a controller to selectively connect only one of the inputs to the single output to enable conveyance of the output from one of the devices connected to the selected input through the switching component to the single output of the switching component and then to the display such that the video component of the output signals from the devices that represent different measurements by the devices derived from tests conducted by the devices on the same unit under test are selectively displayed on the display, the switching component and the controller being housed in a separate housing from the plurality of devices and from the display. - View Dependent Claims (22)
