Mobile high-definition link (MHL) compliance

Engineers designing and validating the MHL physical layer and link layer of their devices face constant pressure to improve efficiency. Engineers need to perform a wide range of compliance tests quickly and reliably right on their bench.

The MHL 1.1/1.2/1.3/2.0/2.1/3.3 specifications support MHL, which enables mobile devices to transmit uncompressed audio/video to an HDTV or receiver with HD capability. Option MHD and MHD3 Advanced Analysis and Compliance Test Software meets the MHL 1.1/1.2/1.3/2.0/2.1/3.3 CTS specification and automates a comprehensive range of tests, enabling unprecedented efficiency with reliable results. TEK-PGY-MHL-PA-SW MHL Protocol Analyzer Software supports up to 1.1/1.2/2.0 and 1.3/2.1 CTS specification.

Reliable and dependable results

Option MHD and MHD3 software embeds the MHL CTS 1.1/1.2/2.0 and CTS 1.3/2.1/3.3 compliance test procedures, ensuring dependable results. Accurate jitter testing and precise violation testing delivers higher credibility. Perform transmitter tests with simple setups that eliminate nonlinearity. Authentic measurement techniques and automation eliminate errors to provide faster test times.

Option MHD and MHD3 leverages the TekExpress capability to provide smooth multi-equipment interactions, providing an automated solution for transmitter, sink, and dongle testing. The direct synthesis method ensures greater repeatability:
