Manufacturer Agilent Technologies

Keysight Technologies

Description :

The Keysight Technologies U4998A HDMI and MHL 1.4b protocol / audio / video analyser and generator module enables you to test your devices to ensure they are compliant to the HDMI 1.4b or MHL 1.2 compliance test specification (CTS). The U4998A directly replaces the N5998A, Keysight Technologies’s previous generation HDMI protocol / audio/ video analyser and generator recommended by the HDMI CTS. The U4998A is recommended by the HDMI CTS 1.4b for 4K x 2K compliance testing (Test 7-39).

The U4998A AXIe-based module is the first instrument to support source and sink compliance testing up to the maximum transition modulated differential signaling (TMDS) data rates of 3.4 Gbps – essential to support 4K x2K resolution. In addition, the module’s wide range of capabilities enable you to test legal codes, basic protocol, packet type, pixel encoding, video format timing, AVI Infoframe, ACR, audio sample packet jitter, deep color, 3D video format, and more.

Have confidence in obtaining CTS certification on the first pass by performing in-house testing with the same equipment used by AT. Perform deeper analysis and identify the root cause of failures with the N5998U-DBG option. ; Automate your HDMI testing and remotely control the U4998A using the COM server embedded in the application software.

The U4998A HDMI is controlled by HDMI analysis software running on an external PC. The HDMI analysis software is part of the U4998A.
