QD804A (4K)
The rack mountable model 804 and 804A video test generators are optimized for testing modern HDMI flat panel TVs. The 804 video test generator supports testing of HDMI resolutions operating up to 225MHz. The 804A video test generator supports testing of HDMI 4K x 2K resolutions up to pixel rates of 300MHz. This enables testing ultra HD TVs with 4K resolutions at 30Hz and at 50/60Hz using HDMI 2.0 4:2:0 pixel encoding. The 804A also supports testing with HDMI 2.0 21:9 format resolutions at or below 300MHz.
These instruments feature four (4) HDMI outputs, all active simultaneously for testing HDTVs with multiple HDMI inputs. This eliminates the need for splitters, often required to test each HDMI input on an HDTV. The 804 and the 804A can output component analog and composite analog video and HDMI. Switching between video timings and images is fast. The 804 and 804A are 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 804 and 804A tests compressed and uncompressed HDMI audio formats using a variety of audio test signals. An HDTV's analog audio inputs can also be tested using the 804's programmable analog audio outputs.
Manufacturing engineers can operate either 804 series instrument in a few different ways. The user-friendly touchscreen interface can control the instrument, which also provides status during testing. For control by an automated test system, the 804 and 804A can be operated through an extensive command set. The 804 series instruments support 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.
The 804 and 804A provide the necessary features and functions for testing HDTVs on a production and are offered at an attractive price. Contact your Quantum Data distributor or representative for ordering and pricing information.
