Operating Information

Connecting the Data Store System Input and Outputs

The Data Store system is an integral part of all MPEG Test Systems but the MTS 205; it enables transport stream capture and output at up to 60 Mbps.

Figure 2–1 shows the Data Store System input and output (I/O) connectors on the computer rear panel. A detailed description of each connector follows the illustration. For I/O port specifications, refer to the Specifications section of this manual.

Use the I/O ports that best suit your operating environment and signal sources. To receive ASI input, use the optional D6002 DVB-PI adaptor. (Contact your Tektronix representative for ordering information.)

ECL Parallel/Serial I/O Port

2–2

The ECL Parallel/Serial I/O port receives and transmits MPEG-2 transport streams at ECL levels. The port is differential, bidirectional, and operates independently or in conjunction with the ECL Control port. The port transmits or receives either parallel or serial data depending on the Data Store Administrator application settings.

MPEG Test System, Compaq Proliant Platform

Operating Information

ECL Operating Modes. If the ECL Parallel/Serial I/O port is used independently of the ECL Control port, there are three basic operating modes:

H Slave acquisition mode. Captures input signals using the ECL Parallel/Serial

I/O port clock signal as the timing source.

H Master generation mode. Outputs signals using the test system internal clock

as the timing source.

H Master generation with external clock mode. Outputs signals using the

external clock input (Clk In) as the timing source.

Using the ECL Parallel/Serial I/O port in conjunction with the ECL Control port provides the following additional operating modes:

H Master acquisition mode. Captures input signals using control signals from

the ECL Control port to drive the signal source.

H Master acquisition with external clock mode. Same as above, but uses a

timing signal from the external clock input (Clk In) as the timing source.

ECL Control Port

G.703 Output

(8.448 and 34.368 Mbps)

and G.703 Input

H Slave generation mode. Outputs signals using the ECL Control port inputs as

the timing source.

NOTE. A“Master” generates the data transmission clock. A “Slave” returns an external clock as the source.

Pinouts. For pinouts of the ECL Parallel/Serial I/O port, see Tables 1–4 and 1–5 beginning on page 1–7.

Using the ECL Control port is optional. This bidirectional differential control port adds flexibility to the ECL Parallel and Serial Ports, providing three control signals and two more operating modes. For a pinout of the ECL Control port, see Table 1–6 on page 1–10.

The G.703 serial interface complies with the electrical characteristics of ITU-T Recommendation G.703 (HDB3 code) for 8.448 Mbps and 34.368 Mbps.

The G.703 port operates in the following modes:

H Acquisition mode. Locks to incoming the signal and is self clocking. H Generation (internal clock source) MODE. Uses an internal clock source.

The G.703 serial interface uses three Data Store circuit-board mounted SMB connectors. One connector is a dedicated input for both bit rates. The other two

MPEG Test System, Compaq Proliant Platform

2–3

Operating Information

connectors are dedicated outputs, one for the 34.368 Mbps output and the other for the 8.443 Mbps output. To reduce spurious emissions, connect only the output being used.

10 Mbit Serial Port

(RS-422 Levels I/O Port)

Clock Input

The 10 Mbit Serial port transmits and receives MPEG transport signals and includes bidirectional clocks and data pairs. The maximum operating frequency is 10 Mbps. The port uses RS-422 voltage levels with a line-to-line input termination of 110 W. For a pinout of the 10MBit Serial port, see Table 1–10 on page 1–12.

The 10 Mbit Serial port uses the following signals:

H Data In and Data Out (MPEG serial bit streams). H Clock In and Clock Out (continuous data transmission).

The 10 Mbit Serial port operates in the following modes: H Acquisition mode. Captures an input signal using an external timing

reference.

H Internal generation mode. Generates an output signal using the Tektronix

MPEG Test System internal clock as the timing reference.

H External generation mode. Generates an output signal using the Clock input

as the timing reference.

The Clk In connector provides an optional timing input for the ECL Serial, ECL Parallel, TTL, and 10 Mbit Serial outputs. The input operates at a maximum frequency of 45 MHz.

TTL 50 W Serial Port

(Data & Clock I/O)

2–4

The TTL 50 W Serial Port consists of dedicated clock and data inputs that transmit and receive at TTL levels. The Data signal is a serial bitstream that uses a continuous data transmission clock. The maximum operating frequency is 45 Mbps.

The

TTL 50 W Serial Port operates in the following modes:

H Acquire mode. Captures an input signal. H Internal Generation mode. Generates a signal locked to the internal clock. H External Generation mode. Generates a signal locked to an external reference

supplied by the Clock Input.

MPEG Test System, Compaq Proliant Platform

Operating Information

Data Store I/O Cables and

Mating Connectors

The Tektronix MPEG Test System includes adapters to connect the Data Store SMB connectors to standard BNC connectors. You may also need to acquire or assemble other signal-connecting cables and adapters to install the test system in your facility.

Cable Lengths. Maximum cable length is a function of data rate, cable type, and ambient environment as summarized in Table 2–1. In general, low data rates tolerate long cable lengths better than high data rates. Low loss coaxial cable and low capacitance properly pair-twisted cable support longer transmission paths than do miniature coaxial cable or ribbon cable. Induced RF noise can further limit usable cable length.

The only test system ports designed for data transmission are the G.703 I/O ports. All others ports are intended for short-range interconnects. With most ports, you must control cable delay matching to maintain clock-to-data timing margins or data integrity will suffer.

Adapters. The Tektronix MPEG Test System includes six SMB-to-BNC adapter cables. Three of the adapter cables match the impedance of the G.703 75 W inputs and outputs. The other three match the impedance of the TTL 50 W Serial Port (CLK I/O, DATA I/O, and CLK IN).

NOTE. Do not leave SMB-to-BNC adapter cables on unused G.703 outputs. Doing so can cause the test system to exceed EMC emission requirements.

Operating Information

The Serial output stream is always equivalent to the input stream and is not affected by selections made on the Filtering Configuration tab of the Real-Time Analyzer Settings window.

Refer to Table 1–16 on page 1–15 for serial output characteristics.

Trigger Input

The trigger input accepts a TTL level (0 to +5 V) signal you can use to control capture of the Real-Time Analyzer input stream to the Data Store system (MTS 215 only). You can configure the system to start/stop data capture on either the rising edge (low to high transition) or the falling edge (high to low transition) of the trigger signal. Refer to the Real-Time Analyzer User Manual for further information.

Connecting the Synchronous Serial Interface Input and Outputs

The Option SS synchronous serial interface (SSI) converts MPEG-2 SMPTE 310M compliant synchronous serial transport streams at 19.39 and 38.78 Mbps to synchronous parallel ECL output compatible with the the MPEG Test System Data Store and Real-Time Analyzer hardware. The interface also converts DVB-compatible serial data streams to parallel output. The SSI data conversion operates in both receiver and generator modes from 10 to 50 Mbps.

Figure 2–4 shows the SSI input and output connectors on the computer rear panel. A detailed description of each connector follows the illustration.

SSI Output

ECL Parallel I/O

The SSI interface converts synchronous serial data from this input to synchronous parallel ECL output for the Data Store System or Real-Time Analyzer.

When an SSI signal is present at the SSI IN BNC connector, synchronous parallel data is output through the ECL PARALLEL I/O connector and available for input to Data Store System or Real-Time Analyzer ECL parallel inputs.

The SSI interface outputs synchronous serial data through the SSI OUT BNC connector when a synchronous serial signal is present at the SSI IN BNC connector (active loop-through). You must terminate this output into 75 ohms. When no SSI input is present, the SSI output will be converted from the ECL parallel input.

Synchronous parallel signals input to the parallel I/O connector (from the Data Store System or Real-Time Analyzer ECL parallel outputs) are converted to synchronous serial data if there is no signal present at the SSI IN BNC connector. The output is available at the SSI OUT connector. The SSI output bit rate is identical to the parallel input bit rate. Synchronous parallel interface (SPI) output is ECL-level compatible.

NOTE. Use the SSI Parallel I/O connector as an ECL bi-directional interface to the Data Store System or Real-Time Analyzer.

Theory of Operation

A Tektronix MPEG Test System consists of a Personal Computer platform to which a Data Store system and/or a Real-Time Analysis (RTA) system are added. The computer portion of the system is referred to as the server. The Data Store and RTA circuit boards are installed in the server EISA card cage. The boards communicate with the server via the EISA bus. See Figure 3–1. The application software that runs on the Windows NT operating system is resident on the server system disk (the C drive).

The Data Store circuit board, the four SCSI Controller circuit boards, and the four added hard disk drives make up the Data Store system. The system can acquire and generate transport streams of up to the size of the total Data Store disk drive capacity without looping. Data store capacity of test systems with serial number B059999 and earlier is 8 Gbytes; capacity of later test systems is 18 Gbytes.

The RTA circuit board decodes the input stream and enables instantaneous analysis, with the Real-Time Analyzer software, of many stream characteristics.

Option SS is a format converter circuit board that converts between SSI (Synchronous Serial Interface) and ECL parallel, in both directions.

The mouse and keyboard provide user control of the system. The mouse interface uses the standard Windows “point and click.” The graphical user interface (GUI) displays Windows NT compliant icons, menus, and drop-down lists on an SVGA monitor.

Data Store

Theory of Operation

The Data Store circuitry controls the acquisition, storage, and output of the data that makes up the MPEG transport stream. It outputs test signals that can be used to evaluate downstream circuits. The Data Store system consists of the Data Store circuit board, four SCSI Controller boards, and four Data Store disk drives.

Data Store Circuit Board

SCSI Controllers

Data Store Disk Drives

The Data Store circuit board controls the acquisition, storage, and output of transport stream data. The board contains a 16 MHz central processing unit (CPU) and an 8-bit common bus with a 16 Mbyte/s transfer rate. Communication between the server and the Data Store circuit board occurs over the EISA bus. Data transfers from the server to the Data Store Disks use a 32-bit direct memory access (DMA) with a read/write enable to the Data Store CPU.

The Data Store circuit board generates several clocks for synchronization. A phase lock loop synthesizer locks to either internal or external clocks to produce clock signals ranging from 1 MHz to 60 MHz. Two crystal oscillators provide internal clocks at the 8.448 MHz and 34.368 MHz G.703 bit rates.

There are four SCSI Controller boards mounted on the Data Store circuit board. The SCSI Controller boards provide the interface between the Data Control board and the Data Store Disks. Each SCSI Controller board has 512 Kbytes of random access memory (RAM) buffer to support transfers between the Data Control board and one of the four Data Store Disks.

The four hard disk drives, numbered 1 through 4, are located in the server drive bay. The drives share a common power supply from the server mainframe. Each drive connects directly to a SCSI Controller board through a dedicated SCSI bus cable.

External I/O

MPEG Test System, Compaq Proliant Platform

There are four separate transport stream I/Os in the Data Store System: H The G.703 serial interface acquires and generates MPEG transport streams

that comply with the ITU-T G.703 standard.

H The 10 Mbit/s serial interface is a differential I/O that incorporates both data

and clock. It operates at RS-422 voltage levels.

H The TTL interface is a bidirectional serial interface that uses a continuous

data transmission clock.

H The ECL parallel/serial port provides a differential, bidirectional interface for

100k ECL transport streams. The separate control port can be used to control this parallel/serial port to provide additional operating modes.

3–3

Theory of Operation

G.703. The G.703 serial interface consists of a single input to and two outputs from the Data Store circuit board. The input port accepts ITU-T Recommendation G.703 (HDB code) 8.448 Mbps and 34.368 Mbps streams and operates in the unframed mode.

The two G.703 outputs provide 8.448 Mbit/s and 34.368 Mbit/s transport streams. These output streams use the internal crystal controlled clock for their timing reference.

10 Mbit Serial Port. The 10 Mbit serial port inputs and outputs both differential data and a differential clock. The port has separate pins for incoming data and outgoing data. Input lines are terminated 110 W line-to-line. Output lines should be terminated at the far end. This port can use either the internal clock or an external clock as its timing reference.

TTL 50W Serial Port. The TTL 50 W serial port consists of a serial data line and a continuous data transmission clock. Its maximum operating rate is 45 Mbps. The port acquires a transport stream using the transmission clock as its timing reference. The output transport stream can be locked to either the internal phase locked loop or an external clock to provide the timing reference. The enhanced output drives a 50 W grounded load.

ECL Parallel and Serial Port. A single connector supports both parallel and serial differential I/O functions. The operating levels for both parallel and serial interfaces are 100k ECL. All input lines are terminated 110 W line-to-line. The ports are bidirectional and can use either the internal phase locked loop or an external clock as a timing reference.

Serial data rates to 55 MBits/s are possible using the internal PLL. The maximum parallel data rate is 60 Mbps (7.5 MBytes/s).

A separate control port can be used to provide additional slave generation and master acquisition data transfer modes. When using the control port, hand-shaking signals from the master system control the data transfer. This means the direction of signal flow from the control port is opposite the data transfer direction. For example, in the master acquisition operating mode the master system sends the control signals and receives the data. The slave system receives the control signals and sends the data.

MPEG Test System, Compaq Proliant Platform

Real-Time Analysis

Theory of Operation

The real-time analysis (RTA) hardware and software can continuously monitor input bit streams for compliance with MPEG-2 and DVB-SI standards.

Real-Time Analyzer

Circuit Board

External I/O

The Real-Time Analyzer circuit board contains circuitry that decodes incoming transport stream packets so that analysis can be performed. The board also contains a DSP to generate rate and allocation data for the PIDs and Programs carried in the transport stream. Packets that contain PCRs are time-stamped so that the application can perform PCR jitter, frequency offset, and arrival interval analyses.

The RTA contains both parallel and ASI (Asynchronous Serial Interface) ports for data input and output. The user can select the input through the RTA Configuration menu. The parallel output is live whenever the RTA is analyzing an input stream; however, the ASI output is active only when the ASI input is used.

Parallel Input. The parallel port is a 25-pin D-connector; pin assignments correspond to the DVB SPI interface standard. All input lines are differential and are terminated with 100 ohms line–to–line. The input is functional with signal levels of LVDS, ECL, or TTL (RS–422).

ASI Input. The ASI input port is a BNC connector terminated in 75 ohms. Parallel Output. The parallel output port is intended primarily as a method to

transfer a portion of the input transport stream to the Data Store system for capture and in-depth, deferred-time analysis. Capture may be initiated manually or triggered by a selected error in the transport stream. You can configure the parallel output to either LVDS or modified ECL levels through the RTA Configuration menu. When capturing to the Data Store system, select modified ECL output levels.

The input transport stream, or selected portions of the input stream, are passed to the parallel output whenever analysis is occurring. The user may specify, through the RTA configuration menu, which PIDs or programs are to be passed through to the output. The RTA uses the DEN line to accomplish this PID-based filtering.

ASI Output. When the ASI Input is selected, the input data is also present in the ASI output. Parallel input is not passed to the ASI output, and PID-based filtering does not affect ASI output.

MPEG Test System, Compaq Proliant Platform

3–5

Theory of Operation

SSI Format Converter (MTS200 Option SS)

The Option SS format converter circuit board converts between SSI (Synchronous Serial Interface) and ECL parallel, in both directions. The circuit board is installed in slot 5 of the Proliant computer platform and it has a PCI connector and form factor. It draws power only from the PCI bus and does not require any software drivers or setup.

NOTE. Option SS is not supported on test systems using Prosignia platforms.

Format Conversion

Transport Rate

SSI Output Amplitude

An SSI format transport stream can be converted to ECL parallel for input to the Real-Time Analyzer or the Data Store circuit board for acquisition and in-depth analysis. Also a transport stream in the SSI format can be generated by driving the parallel port with the parallel output of the Data Store hardware.

The ECL parallel port of the SSI board is bi-directional, whereas the SSI input and output ports are dedicated BNC connectors. The mode of operation (input or output) is not controlled by software, but depends on whether there is a signal on the SSI input. If an input signal is present, the board will convert the SSI input to an ECL parallel output. If there is no SSI input, the board will switch to converting any signal on the parallel port to a SSI output.

The SSI Format converter board operates with transport rates between 10 and 50 Mbps. This includes the SMPTE 310M rates of 19,392,658 and 38,785,317 bps. When generating an SSI signal, the SSI transport rate is dependant on the rate of the Data Store circuit board.

Jumper J5 on the SSI format converter board sets the SSI output peak-to-peak amplitude to, nominally, 800mV (for SMPTE 310M environments) or 1.0 V (for DVB environments). The default factory setting is 800mV.

Performance Verification

Performance Verification, Data Store System

This section contains procedures for verifying that the Data Store system, an integral part of the MTS 210 and MTS 215, meets the performance requirements listed in the Specifications section.

It is common for Tektronix MPEG Test System operators to use only one or two of the I/O ports. To minimize test time, you can verify only the I/O ports that are used by the system operators. Refer to the Procedure Structure section on page 4–5 for information about running tests for specific I/O ports.

If the instrument cannot pass these tests, refer to the Maintenance section for troubleshooting procedures.

NOTE. To perform the procedures in this section, you must have a basic understanding of the Windows NT operating system and the MPEG Test System Data Store Administrator application. For detailed operating instructions, refer to the Windows NT documentation and the appropriate MPEG Test System User manual.

Verification Interval

Perform the procedure once every 2000 hours of operation or every 12 months to ensure that the performance is within tolerance.
