1About the 980
This chapter provides an overview of features of the 980 Protocol Analyzer and the 980 Manager. The 980
Protocol Analyzer is an HDMI and MHL analyzer for source devices. It provides visibility into the HDMI/MHL
protocol to help resolve common interoperability problems in HDMI/MHL systems. The 980 Manager is a PC
application to manage and use the 980 Protocol Analyzer.
There are two options for the 980: 1) 980 225MHz “Gen 2” and 2) 980 297MHz “Gen 3”. The 980 225MHz “Gen 2”
is able to parse HDMI/MHL streams from source devices with a TMDS clock up to 225MHz. The 980 297MHz “Gen
3” version is able to parse HDMI streams from source devices with a TMDS clock and pixel clock up to 297MHz
and MHL streams up to maximum speeds.
Note: Only the 980 297MHz “Gen 3” version supports MHL protocol analysis.
1.1 What makes the 980 Unique?
The 980 Protocol Analyzer for HDMI or MHL source devices provides full visibility into the protocol, timing, control
and auxiliary data. It captures and decodes encrypted or unencrypted metadata (audio sample, infoframes and
other data packets) as well as DDC transactions and CEC messages (C-Bus transactions for MHL).
Competitive “analyzers” available on the market are more limited because they utilize commercial silicon chips.
The 980 uses a proprietary solution and therefore can provide much greater visibility into the protocol, timing and
control data. The competitive “analyzers” support some of the 980 features but not nearly all of them. They support
functional testing but not true interoperability testing. Functional test “analyzers” often support only real time
monitoring. The 980 supports capture and store as well as Real Time monitoring.
For these same reasons, the 980 can support all of the tests in the HDMI and MHL source protocol compliance test
specification. Functional test instruments cannot. For example, the 980 supports all the Protocol tests in Test 7-17
of the HDMI Compliance Test Specification and the Basic Protocol Tests in the section 3.2.2.2 in the MHL
Compliance Test Specification related to control periods, preamble and guard bands. Similarly the 980 can

980 User Guide –MHL Compliance Tests Rev. B29
Page 4 July 26, 2011
measure the audio sample rate precisely and therefore measure audio jitter correctly. Functional test instruments
cannot support these tests correctly.
1.2 Scope of this User Guide
This User Guide provides descriptive and procedural information on the MHL compliance test options for testing
MHL sources and sinks. Although you can run the compliance tests through the 980’s “embedded GUI,” all the
examples used in the procedures in this document are taken from the external standalone PC 980 GUI Manager.
The procedures are identical between the embedded GUI running through the 980 front panel display and the
external standalone PC application but the look and feel is slightly different.
1.3 Changes to this User Guide
This is a new document.
Note: Please be sure to check the Quantum Data website for updates to this User Guide.
1.4 What options are available with the 980?
The 980 offers six options that you can purchase with the 980 Protocol Analyzer but only two of these pertain to
MHL: 1) Encrypted Link Analyzer mode for monitoring encrypted data between an HDMI source and sink device. 2)
HDMI Source Compliance tests in accordance with HDMI 1.4 CTS Sections 7.4 through 7.8. 3) EDID Compliance
test in accordance with Sections 8.2 and 8.5 of the HDMI 1.4 CTS. 4) HDMI Sink Compliance tests in accordance
with HDMI 1.4 CTS Sections 8.4 through 8.8. 5) MHL Source Compliance tests in accordance with MHL 1.0 CTS
Section 3. 6) MHL Sink Compliance tests in accordance with MHL 1.0 CTS Section 3. The MHL Sink Compliance
test suites require the Quantum Data 882E or 882EA instrument, release 2.25.0 which uses firmware
version 20.1887600.
You must have a license to use these optional features.
You can determine what options the 980 is provisioned with by looking at the label on the bottom of the 980 or by
accessing the Instrument Information screen on either the built-in or external GUI manager. Refer to the following
screens.

Page 5 July 26, 2011
1.5 980 User Interface
The 980 Protocol Analyzer provides a graphical user interface for operation. This GUI can run both on the 980 itself
through the built-in color touch screen display or as a standalone application running on a PC. The look and feel
and functions are similar but not identical.
1.5.1 980 GUI Manager
The external 980 GUI Manager provides easy access to the captured data on your PC for sharing with others. Also
the external 980 GUI Manager enables you to operate the 980 through a larger interface which allows you to use
multiple panels at the same time. There are two key features that are not available in the external 980 Manager
GUI however: 1) viewing the video in real time, 2) viewing the MHL video/audio metadata and DDC (MHL C-Bus)
transactions in real time using the Real Time mode.
1.5.2 980 Embedded GUI Manager –Real Time Monitoring
You can operate the 980 fully through the built-in color touch screen display. In addition to the basic operation of
the 980 Protocol Analyzer the touch screen display GUI also enables you to view the incoming video from a source

980 User Guide –MHL Compliance Tests Rev. B29
Page 6 July 26, 2011
even when encrypted with HDCP content protection. The ability to view the incoming video also enables you to
control the menus of the MHL source device to ensure that it is in the correct mode. The built-in GUI also enables
you to view the MHL video metadata and DDC (MHL C-Bus) transactions in real time, as they are being captured,
using the Real Time mode.
You can transfer data captures taken from the built-in touch display to your PC where they can be viewed through
the external 980 GUI Manager and also disseminated to others for analysis.
1.6 What kinds of data does the 980 Protocol Analyzer allow you to view?
By providing visibility into the HDMI protocol, the 980 Protocol Analyzer enables you to detect changes and identify
anomalies in the HDMI signal. The following is a list of the data types you can view (currently):
Video
oTiming parameters
oPixel values
Data Islands, including:
oInfoframes (AVI, Audio, Source Product Descriptor, etc.)
oGeneral Control Packet (GCP)
oAudio Clock Regeneration (ACR)
oAudio Sample Packet Header including Channel Status Blocks
oControl data (vsync, hsync, encryption enable)
Control data

2.5 Connection Scenarios for 980 Manager to 980 Protocol Analyzer
This subsection describes the options for connecting the external 980 Manager to the 980 Protocol Analyzer. In
order to operate the 980 Protocol Analyzer with the 980 Manager you will need to establish a connection between
the 980 Protocol Analyzer and the 980 Manager. The 980 Manager will be running on your laptop or host PC. You
will either be connecting directly from the 980 Manager to the 980 Protocol Analyzer through an Ethernet cable or
you will be connecting through your corporate LAN network.
If you are connecting directly between your host PC and the 980 Protocol Analyzer you will need to ensure that the
IP addresses of the 980 and the network interface card on your host PC are compatible. To be compatible, the IP
addresses must have the same network portions of their IP address but different host portions. You can either
change the IP address of the host PC using standard Windows OS techniques or you can change the IP address
of the 980. The 980 is provisioned with a default IP address (192.168.1.10). The procedures for changing the IP
address of the 980 are provided in the next subsection.
If you are connecting through your corporate LAN, the PC that the external 980 Manager is running on will typically
have an IP address assigned to it through DHCP services. You can either assign an IP address to the 980 directly
or allow the network DHCP server to assign one to the 980 that is compatible with your corporate network. To be
compatible, the IP address of the 980 must have the same network portion of the IP address as your network but a
unique host portion. The 980 is provisioned with a default IP address (192.168.1.10). The procedures for changing
the IP address of the 980 are provided in the following subsection. These procedures also describe how to enable
the 980 DHCP client to allow the network to assign an IP address.
2.5.1 Setting the IP address of the 980 Protocol Analyzer
This procedure describes how to set the IP address of the 980 Protocol Analyzer manually. You can change the
980’s IP address through the 980’s front panel touch screen display. You can also allow the network DHCP server
to assign an IP address. This procedure assumes that you have powered up the 980 and that the embedded 980
GUI Manager has been launched.
