1 Introduction
HDMI Frame Generator - Overview
The HDMI (High-Definition Multimedia Interface) Frame Generator
software (also known in short as “Frame Generator” or “software”) is a
stand-alone software utility. It provides semi-automatic control of Keysight
Technologies’ M8195A AWG (Arbitrary Waveform Generator) TMDS and
FRL Signal Generator for physical layer tests.
The Frame Generator is a flexible tool for trouble-shooting and debugging.
it complements the full Test Automation Software (N5991HP1A), which
provides automated physical layer compliance tests and device
characterization. It allows a wide range of HDMI video formats to be
generated and provides control over parameters such as color depth and
color code. It comprises jitter insertion for jitter tolerance tests to set the
skew and other key parameters. The software runs on a standard Windows
PC and controls the hardware test resources through appropriate
interfaces, such as a LAN (Local Area Network).

2Test Instrument Setup
M8195A Single Module setup / 10
M8195A Two Module setup / 11
Prior to using the HDMI Frame Generator software for connecting
instruments, Keysight recommends setting up the test instruments and
establishing the required connections.
1 Connect the instruments (AWG and other instruments, such as, signal
and waveform generators) to the controller PC via USB or LAN.
2 Establish all required cable connections between the instruments and
the DUT (device under test).
3 Switch on the PC and instruments.
4 Start Keysight “IO (Input Output) VISA (Virtual Instrument Software
Architecture) connection Expert” and check the connections for the
instruments.
5 Set the correct IP addresses for the instruments.
The AWG setup can be used in two different configurations:
• based on single M8195A module (TMDS only)
• based on two M8195A modules and an M8197A synchronization
module

2 Test Instrument Setup
M8195A Single Module setup
This setup consists of a limited HDMI test configuration.
It does not have any instrument intra-pair skewing capability, can only
reach up to around 8Gbit/s and does not support FRL testing.

For a full coverage of HDMI PHY testing, the M8195A two module setup
(shown further) is required.
