The rack mountable 804A is optimised for testing the latest displays. It features four HDMI 297MHz outputs — all active simultaneously for testing HDTVs with multiple HDMI inputs. This eliminates the need for splitters often required for testing each HDMI input on an HDTV. The 804A can output component analogue and composite analogue as well. Switching between video timings and images is fast; less than 100ms. The 804A is equipped with all the standard video timings and test patterns including support for 3D — necessary for testing HDTVs including tests for HDMI protocols such as HDCP, EDID and CEC.

The 804A tests both compressed and uncompressed HDMI audio formats using a variety of audio test signals. An HDTV’s analogue audio inputs can also be tested using the 804A’s programmable analogue audio outputs.

Manufacturing engineers can choose to operate the 804A in a few different ways. The 804A can be controlled through the user friendly touch screen interface which also provides status of the 804A instrument during testing. For control by an automated test system, the 804A can be operated through its extensive command set. The 804A supports many of the same commands that production facilities have become familiar with on the Quantum Data 802 and 881 series test instruments. Alternatively, an optional programmable keypad can be attached to the USB Port or RS-232 port for keypad control.
