MTM300 Series MPEG Transport Monitor
The Tektronix MTM300 Series MPEG Transport Monitor is a rack-mounted,
MPEG-2 protocol monitor used to monitor single and multiple program transport
streams in MPEG-2, DVB, and ATSC environments. The transport monitor
depicted in Figure 2--1 includes the optional user interface (keypad and
touchscreen).
Figure 2- 1: The MTM300 Series MPEG Transport Monitor
See the MPEG-2, DVB, and ATSC standards for detailed information about the
syntax and semantics of each system.
Each monitor can analyze up to eight transport stream inputs simultaneously and
accepts inputs in the following electrical formats:
H ASI/M2S (the monitor automatically detects the format)
H SMPTE 310M
MTM300 Series MPEG Transport Monitor Service Manual
2- 1
Operating Information
The transport monitor allows you to output alarm signals using a 25-pin serial
interface. Each critical or major error recorded by an Analysis Server closes a
contact tied to the specific input. The pin-out for the alarm relay is provided in
Appendix A: Specifications.
The transport monitor uses a client/server architecture consisting of of a Server
Manager, multiple Analysis Servers, and the following client applications:
H Master client
H Expert client
H Configuration client
All three clients are tightly integrated, making the system easy to use for experts
and non-experts.
Server Manager
Analysis Servers
The Server Manager is the process that makes the results of the Analysis Servers
available to Master clients and starts automatically when you start the transport
monitor. Only one Server Manager can run on a transport monitor or network
management station.
The Server Manager process interacts with the following entities:
H The Analysis Server sends analysis results (called traps)totheServer
Manager.
H The Master client displays the data collected by the Server Manager.
The Analysis Server is the process that actually analyzes transport stream inputs
and starts automatically when you start the transport monitor. One Analysis
Server is started for each transport monitor input. Each transport monitor can
support up to eight Analysis Server processes simultaneously.
The Analysis Server processes interact with the following entities:
H The Server Manager collects the Analysis Server results (called traps).
H The Expert client displays the results of the Analysis Server directly.
H The Configuration client sets the monitoring and analysis parameters for
each Analysis Server process operating on the inputs to the transport
monitor.

Operating Information
Master Client
Expert Client
The Master client provides an intuitive interface for monitoring the status of
transport stream inputs. Of the three MTM300 Series applications, the Master
client is the one you will use most often.
The Master client characteristics are shown in the following list:
H The Bouquet panel displays icons for the bouquets (groups of inputs) that
you have defined for the workspace.
H The Multiplex panel displays icons for the inputs that you have defined for a
bouquet (if enabled).
H The Services panel displays icons for the services (also called programs)
encoded in the transport stream.
H The Details panel displays icons indicating the type, status, and severity of
errors on a transport stream or service.
H Both the Expert and Configuration clients can be started from the Master
client.
The Expert client analyzes a single stream in greater detail. You will use the
Expert client to help troubleshoot errors in your digital transmission system.
The Expert client displays the results of only one Analysis Server (input) at a
time.
The Expert client characteristics are as follows:
H Graphical displays. Show the structure (hierarchy) of the input transport
stream. Display characteristics of each component of the input stream, such
as PID and type allocation, section rate analyses, and timing analyses.
H Report views. Indicate the types of errors recorded by the Analysis Server
and the characteristics of the input stream.
H Error views. Show specific errors recorded for the various components of the
transport stream, such as PMT section rate errors and ETR290 errors.

Operating Information
Configuration Client
SNMP Capabilities
The Configuration client allows you to specify which transport stream parameters are monitored and how errors in your system are reported.
The Configuration client allows you to perform the following tasks:
H Specify the standard to which you test an input: MPEG-2, DVB, or ATSC.
H Set, remove, or modify the probes that test transport streams for valid syntax
and semantics and rates.
H Specify the way in which errors are reported in both the Expert and Master
clients. Y ou can configure each probe to report an error as Critical, Major,
Minor, Warning, or as information only.
H Stop and restart an Analysis Servers running on a transport monitor.
H Set passwords on specific inputs that prevent others from changing the
Analysis Server configuration for that input.
H Set parameters for capturing part of an input transport stream.
The MTM300 Series MPEG Transport Monitor includes two SNMP management information bases (MIB). The Tektronix RTA MIBs are textual descriptions
of the Analysis Server objects (functions and parameters) that can be monitored
and controlled by the network management station using SNMP controls. The
MIB text files are installed with each MTM300 Series MPEG Transport Monitor
installation (on both the transport monitor and a computer with the network
management software installed) at the following location:
2- 4
C:\Mib\, where C is the letter designator of the local hard drive.
The two MIBs located in this directory, RTAv1.mib and RTAv2.mib, are used for
SNMP version 1 and SNMP version 2 systems respectively.
The provided HP OpenView plug-in allows you to integrate the transport
monitor into HP OpenView Network Node Manager network monitoring
systems.

Networking
Operating Information
The MTM300 Series MPEG Transport Monitor comes with the Microsoft
TCP/IP software pre-installed and is designed to operate in TCP/IP networks.
Your network or systems administrator may have already configured the TCP/IP
parameters for your transport monitor. If not, see Appendix C: Networking for
procedures to configure TCP/IP parameters.
To use the transport monitor, you must specify the Server Managers to w hich
you will send error messages. Error messages, called traps, are generated by the
Analysis Servers and sent to one or more Server Managers running on the local
or remote host machines. (A host machine can be either a transport monitor or a
personal computer with the remote desktop or network management software
installed.)
By default, the transport monitor is configured to send traps to the local Server
Manager (using the localhost loopback address as the trap target). If you are
installing the transport monitor into a networked system, you can also send traps
to one or more network management stations. See the procedures described in
Configuring the MTM300 Series MPEG Transport Monitor beginning on
page 2--28 for complete procedures on configuring host machines that have
MTM300 Series modules installed on them.
MTM300 Series MPEG Transport Monitor Service Manual
2- 13
Operating Information
Network Requirements
The Transmission Control Protocol/Internet Protocol (TCP/IP) protocol stack is
pre-loaded on MTM300 Series MPEG Transport Monitors. The open nature of
TCP/IP allows you to create networks using various protocols and signaling
techniques. This section lists the physical and network requirements for using
transport monitors over a network.
Physical Requirements
Minimum Network
Requirements
The physical requirements for networking transport monitors are as follows:
H Ethernet network or subnetwork to the transport monitor
H 10Base-T / 100Base-T network drop to your local transport monitor
H Network interface card (NIC) and driver
NOTE. The Intel EtherExpress Pro/100B Adapter NIC and E100BT.sys adapter
driver are pre-loaded on all transport monitors; this combination of NIC and
adapter driver is the only one supported by the transport monitor.
Network management stations do not have requirements beyond basic connectivity between two points; the network adapter at a network management station
can be of any type that allows it to communicate over a TCP/IP network. The
routers installed in the network convert data to the appropriate format for the
protocols used in your network.
To use the transport monitor over a network, you must install it in a TCP/IP
network. TCP/IP networks have specific addressing and routing requirements
that your network administrator may have already configured.
2- 14
Your network administrator should assign the following TCP/IP parameters to
your transport monitor host machine (refer also to Setting TCP/IP Parameters on
page 2--16):
H Unique IP address
H Unique host name
H Subnet mask (if you are installing the transport monitor in a network with
multiple subnets)
H Default gateway IP address (if your environment uses multiple networks or
subnets)
MTM300 Series MPEG Transport Monitor Service Manual
Operating Information
H DNS server IP address(es) (if you use the DNS service to resolve Internet
addresses; some networks use multiple DNS servers)
H WINS server IP address(es) (if your system uses WINS to resolve computer
names to IP addresses; some networks use multiple WINS servers)
NOTE. To use transport monitors over a network, your network administrator
must assign your host machine an IP address: you cannot use the transport
monitor with Dynamic Host Configuration Protocol (DHCP).

Operating Information
Network Installation
This section tells how to set the parameters listed in Minimum Network
Requirements and configure transport monitors to be managed in an SNMP-
based network management environment. The information in this section
describes only basic network installation procedures and does not replace the
value added by networking professionals.
Setting TCP/IP Parameters
Each network uses specific values for such parameters as IP addresses and
default gateways, so the parameter values used in the examples for this section
are for example only unless otherwise specified. You can configure transport
monitors as stand-alone instruments which need only minimal network parameters set, or you can configure them to be installed into a LAN or WAN (local or
wide area network, respectively).
Display the Microsoft TCP/IP Properties dialog box.
1. Click the Start button on the taskbar, point to Settings, and then Control
Panel. (Alternatively, right-click the Network Neighborhood icon and
select Properties from the shortcut menu. Skip to step 4.)
2. Double-click the Network icon and then select the Protocols tab from the
Network dialog box as shown in Figure 2--4.

must be unique.
MTM300 Series MPEG Transport Monitor Service Manual
2- 17
Operating Information
d. If necessary, enter the subnet mask value and default gateway, both of
which you obtain from your network administrator.
5. Click Apply, and then click the DNS tab.
Set DNS tab parameters.
6. Set the following DNS values as indicated in Figure 2--6:
NOTE. Do not set DNS parameters unless your network uses the DNS service.
Setting these parameters when your network does not use this service will make
your host machine run very slowly when trying to resolve network addresses.
a. Enter your host machine name provided by your network administrator
into the Host name text box. Host/domain name pairs must be unique.
b. Enter the name of the domain of which your transport monitor is a
member in the Domain text box as directed by your network administrator.
c. Click Add in the DNS Service Search Order group, and then enter the IP
address of the Domain Name System server in the TCP/IP DNS Server
dialog box.
d. Click Add to accept your changes and dismiss the TCP/IP DNS Server
dialog box.
It should not be necessary to configure the parameters on the WINS Address
or the Routing tabs.
7. Click OK when you are finished configuring the IP Address and DNS tab
parameters and are certain that all of the values are correct.
8. Restart your transport monitor or network management station for the
TCP/IP changes to take effect.

MTM300 Series MPEG Transport Monitor Service Manual
Operating Information
SNMP Network
Management
Figure 2- 6: DNS tab parameters
SNMP is a communication protocol built on top of UDP/IP. It implements a set
of commands consisting of operations and variables. Equipment or applications
(such as the MTM300 Series transport monitor) that support SNMP present a set
of variables that you can modify or consult as well as a set of notifications. All
of these parameters are grouped into a Management Information Base (MIB).
MIBs are specifications containing definitions of management information so
that network systems can be remotely monitored, configured, and controlled.
Accessing the MIB files. To remotely control the MTM300 Series modules using
any SNMP MIB browser, you must load the RTA MIB files. Two files are
located in the following directory (you need to load only one of them):
C:\Mib\
The two MIB text files found in this directory, RTAv1.mib and RTAv2.mib,are
for managing your transport monitors in SNMP version 1 and SNMP version 2
environments respectively.
The operations in SNMP are limited to retrieving the value of management
information, modifying the value of management information, and reporting an
event.
MTM300 Series MPEG Transport Monitor Service Manual
2- 19
Operating Information
Retrieval. The most common type of retrieval operation requires that the
identities are those that exactly match the identity of returned variables. This
retrieval operation is called GET.
For instance, from a DOS prompt window you can run the following command
to check that the Analysis Server is running on the first input:
getone -v2c <machineName> rta0 rtaStartStop.0
where <machineName> is the network name of the transport monitor for which
you are trying to determine the Analysis Server status.
Modification. There is one modification operation, which is called SET. The
operand for SET is a list of pairs. Each pair consists of the identity of a variable
and its desired value. Use this operation to configure and control a managed
system.
For instance, from a DOS prompt window, you can run the following command
(all on one line) to stop analysis on the first input of a named transport monitor:
setany -v2c <machineName> rta0 rtaStartStop.0
-i stop
where <machineName> is the network name of the transport monitor for which
you are trying to start the Analysis Server.
To restart the Analysis Server, use the same syntax, but change the -i switch
parameter to start.
setany -v2c <machineName> rta0 rtaStartStop.0
-i start
Event Reporting. The SNMP event reporting operation is called TRAP. It
specifies an event and a list of pairs. A pair consists of the identity of a variable
and its value or values. This operation reports the occurrence of events on a
managed system to a list of managers configured to receive events. To send traps
to a specific monitoring station, perform the following steps:
NOTE. A monitoring station can be any host machine on the network running a
Server Manager. Usually, the host machine will be the network management
station, but you can also send traps to Server Managers running on other
transport monitors.

Shutting Down the MTM300 Series MPEG Transport Monitor
There are three ways to shut down the transport monitor: two standard
approaches (depending on whether the transport monitor has a local user
interface), and one hard power down procedure.
Soft Power Down
Standard Power Down
The transport monitor has a soft power down capability that allows you to exit
Windows NT and put the transport monitor in standby. To use this capability,
first exit all open applications running on the transport monitor.
CAUTION. Exit all open applications running on the transport monitor before
using the soft power down capability. Some applications will prompt you to save
unsaved data before exiting. If you do not have a local user interface, you will
not see the prompt, and you may lose data if you remove power to the transport
monitor before Windows NT exits.
To initiate the soft power down process, press and release the On/Stby switch.
After the transport monitor goes into standby, you can restart it by pressing the
On/Stby switch.
To completely remove power to the instrument, disconnect the power cord at the
rear panel.
If your transport monitor has a local user interface, use the normal Windows NT
shutdown procedure to turn off the operating system as described below:
NOTE. To avoid loss of data and possible problems during subsequent
Windows NT initialization, always shut down Windows NT before switching
computer power off.
2- 26
1. Select Shut Down from the Start menu as shown in Figure 2--13.

Theory of Operation
Theory of Operation
The MTM300 Series MPEG Transport Monitor can be used to monitor and
analyze MPEG Transport Streams. The transport monitor consists of modules
that are installed in a standard mainframe platform. The platform is based on a
PC architecture. The mainframe processor has the capability to make the
calculations and data transfers required to perform the analysis and report the
results. The mainframe circuitry also provides the power and user interface
connections to the installed modules.
Mainframe Operation
The functional operation is divided between the mainframe and the transport
monitor modules. The functional description starts with the mainframe and its
capabilities. A simplified block diagram of the mainframe is shown in
Figure 3--1.
The System Bus is contained in a backplane circuit board. The bus directly
connects to all applications modules shown in the block diagram. Full system
bus connections to the application modules are provided.
System Busses
The System Bus contains three sub-busses plus other signal wires:
H Power Sub-Bus. Carries power and ground to the applications modules.
H Control Sub-Bus. A PCI bus.
H Audio Bus. Provides a way to route an audio signal generated on any
application module to the internal speaker and the headphone jack.

Power Supply
Mainframe Controller
The Power Module consists of the Power Conditioning Board, a purchased
power supply, the AC supply connector with line filter, and the power supply
cooling fan. The Power Module supplies the PCI bus voltages through the
backplane connectors that engage when the module is bolted in place. Other
voltages are provided to the mainframe modules through connectors and ribbon
cables.
The power conditioning board distributes power from the main power supply to
the backplane, the front panel, and the SCSI drive connector. The +5 V and
+12 V from the main supply are distributed through current limit circuits to meet
safety specifications. Six additional voltages are generated by DC-to-DC
converters on the power conditioning circuit board. These voltages are the
+7.5 V, --7.5 V, +3.3 V, +15 V, --15 V, and +33 V supplies. The power conditioning board also does the power on/off switching, generates the line trigger,
provides the fan drive voltage, and drives the power good indication circuitry.
A shorted or overcurrent condition on any of the outputs of the main supply will
cause a shutdown and cycling of the main power supply. The DC-to-DC
converters will fold back for an overcurrent condition and will also cause
shutdown of the main supply for a shorted output.
The mainframe controller is a high-performance single board computer that
includes SVGA graphics and I/O circuitry and conforms to the PICMG
backplane standard. The Internal controller mounts vertically at the left of the
mainframe card cage and connects into the PCI backplane through a standard
32-bit PCI connector. A 64-bit PCI connector is used for additional I/O
communication to the backplane. Interconnection to other instrument components and rear panel ports is through a Processor I/O board.
PCI Backplane
Front Panel Interface
MTM300 Series MPEG Transport Monitor Service Manual
The PCI backplane supports up to eight standard PCI modules in addition to the
mainframe controller. Custom application modules installed in the module bay
provide the transport monitor application features and functionality. The
backplane also interconnects the power supply output voltages to the remainder
of the system, including the fans. The precision 33 MHz system clock is
distributed on the backplane, and all communication to, from, and between the
system modules is supported.
The front panel interface assembly interconnects the system controller with the
the floppy disk drive, CD drive, mouse, keyboard, and external USB (universal
serial bus) ports. The PC speaker audio is also routed from the controller to the
speaker through the front panel interface circuit board. The optional mainframe
user interface (display, touch panel, and key-pad assembly) is also routed
through the front panel interface assembly when installed.

SCSI Hard Drive
External SCSI Port
Floppy Disk Drive
The SCSI hard disk drive (HDD) is the main drive for the PC, the C: drive. The
Windows NT operating system and transport monitor application software are
stored on this drive
The hard disk drive interfaces directly with the system controller through a Small
Computer Serial Interface (SCSI) extension of the PCI bus. The hard drive is
mounted in the Acquisition compartment in the lower portion of the chassis.
Segments of the transport stream can be captured in the Data Storage mode and
are stored on this hard drive. The transport streams are input to the instrument
through the transport monitor applications board. The transport monitor
applications board sends the data over the PCI bus to the mainframe controller.
The mainframe controller manages the storage of the data on the SCSI drive.
An external SCSI port is located on the rear of the instrument. The port is a
Wide-SCSI, 68 pin connector, which can be used to attach an additional SCSI
storage device to increase storage capacity or accommodate file transfer. When
no external SCSI devices are attached to the port, the port must be terminated
using the terminator supplied with the transport monitor.
The floppy disk drive is a standard one-half inch drive that supports 3.5-inch,
1.44 Mbyte high density double sided floppy disks.

(Option LC)
The CD drive is a half-height drive similar to standard lap top computers. A CD
caddy is not needed. The CD drive drawer is manually operated to insert and
extract a CD disc from the drive.
PS2 compliant mouse and keyboard ports are provided on the lower left side of
the instrument and also on the instrument rear panel. Either set of connectors can
be used. These ports are interfaced through the front panel processors to the
mainframe controller.
The flat-panel display included in Option LC is a backlighted 10.4-inch diagonal
Active Matrix Thin Film Transistor (TFT) LCD panel. To extend the life of the
backlight and prevent burning of the TFT LCD screen, the cold-cathode
fluorescent backlight can be dimmed to 60% of its maximum brightness with a
custom screen-saver or mainframe utilities applet. A DC switching regulator
board, included as part of the display assembly, provides the backlight high-voltage supply. The LCD display connects to the front panel interface board through
a display adapter board in the display assembly.
The standard 10.4 inch touch panel included in the Option LC is mounted over
the surface of the flat-panel display. The touch panel is active at the same time as
the mouse. A second front panel processor combines the mouse and touch screen
signals to generate and receive standard mouse scan-codes from the system
controller.

Theory of Operation
MPEG Processing Board
On Board Clock
The processing involved with monitoring of transport streams occurs on the
MPEG Processing board, 116-0245-00. It is a PCI form factor board. Installed on
the MPEG processing board are one or two Input/Output mezzanine boards to
receive the transport streams. Two types of Input/Output mezzanines can be
installed on the MPEG Processing board for use with different formats. The Part
Number 116-0246-00 supports the ASI format. The Part Number 116-0247-00
supports the SMPTE310M format. Each mezzanine has two inputs and two
outputs, which provide a looped-through output of the input. The MPEG
Processing board can simultaneously monitor and analyze four transport streams.
Much of the processing on the MPEG Processing board involves compiling data
on the PIDs contained in transport stream. The MPEG Processing is achieved by
several FPGAs and a high speed DSP, 320C6201. The results of the processing
are sent to the mainframe controller over the 32 bit, 33 MHz PCI bus. An
AMCC PCI Matchmaker integrated circuit manages the PCI bus communication.
The mainframe controller manages how the results of the analysis are processed:
for display on a VGA monitor or for transmission over a network.
PIDs containing PCRs are time stamped with the time they arrived at the
instrument. The clock used for time stamping is derived from a precision
10 MHz OCXO located on the board. The frequency of the OCXO can be
adjusted by a multiturn potentiometer as described in the Performance Verification section of this manual. A software algorithm compares the arrival time
stamps with the PCR values contained in the packets, performs calculations and
filtering, and presents the results as graphs of the PCR arrival time Jitter,
Frequency Offset, and Drift Rate. The accuracy of the Frequency Offset
measurement is directly proportionate to the accuracy of the 10 MHz OCXO.
The OCXO should be adjusted to 10 MHZ, ¦1 ppm (10 Hz) to maintain a
Frequency Offset measurement accuracy of 1 ppm.
Memory Mezzanine
MTM300 Series MPEG Transport Monitor Service Manual
A memory mezzanine containing 128MB of SDRAM is attached to the MPEG
processing board. This memory is used by the FPGAs and DSP during processing and also for storage of segments of transport streams. Segments of transport
streams can be stored when the software is configured to initiate Data Storage,
triggered by a selected transport stream error. During the Data Storage configuration, the usable memory (nearly 128 MB) can be allocated to capture one input
transport stream or divided among several inputs. Once a segment of a transport
stream is captured into this SDRAM memory, it is transferred to the system hard
drive in non-real time as a .trp file.

Theory of Operation
ASI Input/Output
Mezzanine
SMPTE310M Input/Output
Mezzanine
A mezzanine which supports the ASI format can be installed on the MPEG
processing board, part number 116-0246-00. On this mezzanine, the ASI input is
transformer coupled to the input of an ASI receiver integrated circuit, CY7B933.
The receiver integrated circuit extracts the MPEG data from the ASI stream and
presents it as parallel data on its output. The parallel data is a common format
that all the input/output mezzanines use to transfer the MPEG stream to the
MPEG processing board.
The ASI Input/Output board also provides an active loop through output of the
input. The parallel data is presented to an ASI transmitter integrated circuit,
CY7B923 which transfers the data into the ASI format. The ASI stream is
transformer coupled to the output BNC connector.
A mezzanine which supports the SMPTE301MI format can be installed on the
MPEG processing board, part number 116-0247-00. On this mezzanine, the
SMPTE310M input is transformer coupled to the input of a receiver integrated
circuit, CLC014. The output of the receiver integrated circuit is presented to a
phase-lock loop which locks to the clock frequency contained in the input
stream. The phase-lock loop uses a crystal to achieve high stability. The clock
from the phase-lock loop is used in the process that extracts the MPEG data from
the SMPTE310 stream. The serial data is then converted to a parallel format. The
parallel data is a common format that all the input/output mezzanines use to
transfer the MPEG stream to the MPEG processing board.
The SMPTE310M Input/Output board also provides an active loop through
output of the input. The data is reclocked using the clock derived from the phase
lock loop and presented to the output BNC through a capacitor.
