Introduction

Introduction
The E6292A SMPTE (Society of Motion Picture and Television Engineers) 310M interface is serial-to-parallel converter that receives a synchronous serial SMPTE signal and converts it to a DVB-Synchronous Parallel Interface (DVB-SPI) signal. This DVB-SPI signal is then output to the DVB-SPI receiver on the MPEGscope main card via an external cable which is included with your installation kit. The SMPTE 310M interface enables you to test the connectivity of multiplexers and transmission equipment carrying ATSC-compliant transport streams.
This manual shows how to install the SMPTE 310M interface card into your MPEGscope Plus, MPEGscope Lite, MPEGscope Portable, or MPEGscope Portable Lite test system. Each step provides photographs and easy-to­understand explanations. The manual also includes illustrations and physical specifications for the interface and connectors.
Installation kit Before beginning, ensure that your SMPTE 310M interface installation kit contains
the following items:
SMPTE 310M Interface Installation Guide (E6292-94000)
SMPTE 310M Interface Printed Circuit Assembly (E6292-66501)
DVB-SPI Y-Adapter Cable (E6292-64300)
Size 15 Torx Head Screwdriver (8710-1622)

MPEGscope Plus (E6277C)

MPEGscope Plus and MPEGscope Lite

MPEGscope Plus and MPEGscope Lite
This section explains how to install the SMPTE 310M interface into the MPEGscope Plus or Lite models. Normally, you will install the interface into slot 3, the optional line interface slot. If you have a different MPEGscope PC than the one illustrated below, you can still follow the procedure described in this section, as the affected cards are installed in the same slot positions.
slot 6—video card
slot 5—PCI LAN card
slot 4—MPEGscope main card
slot 3—optional line interface slot slot 2—Real-time Analyzer card
slot 1—(empty)
Note If your MPEGscope is housed in a Kayak XU PC and you also have another
optional interface (such as the ASI & Serial ECL (DHEI) interface), you can rearrange the cards so that both the SMPTE 310M and the optional interface are installed at the same time. This alternative configuration is shown on page 9.

Step 1: Remove the cover

WA R N I N G Never remove the computer cover without first removing the power cord from the
power outlet and any connection to a telecommunications network.
Power off your PC.
1
Unplug the AC power cord from the
2
rear of the PC.
If you are connected to a
3
telecommunications network, disconnect the network cable.
If you are connected to a system
4
under test, disconnect the line interface cable(s).

Step 2: Remove optional interface

Complete this step if your MPEGscope already has an optional interface installed and you want to replace it with the SMPTE 310M interface. For an alternative card configuration, refer to page 9.
IMPORTANT:
Attach the antistatic wrist strap to your wrist and to the PC chassis as described in the
1
instructions on the envelope. Ensure that the copper foil end of this strap attaches to an electrical ground.

Step 3: Install SMPTE interface

IMPORTANT:
Install the SMPTE 310M interface card into slot 3 and screw the
2
faceplate to the PC chassis. (If this is the first interface installed into slot 3, you will have to remove the blank faceplate first.)
Attach the antistatic wrist strap to your wrist and to the PC chassis as described in the instructions on the
1
envelope. Ensure that the copper foil end of this strap attaches to an electrical ground.
If your MPEGscope has a Real-time Analyzer,
3
reconnect the ribbon cable from the MPEGscope main card to the Real-time Analyzer card.

Alternative configuration
Remove the cards from slots 2, 3 and 4, disconnecting cables as necessary.
1
Attach the IAB ribbon cable to
3
the MPEGscope main card then install the card into slot 3.
This configuration applies only if your MPEGscope is housed in a Kayak XU PC (e.g., E6277B or E6277C). It enables you to have both the SMPTE 310M interface and another optional line interface (e.g., the ASI & Serial ECL (DHEI) interface) installed at the same time. The configuration requires repositioning all MPEGscope cards into the first four slots, and replaces Steps 2 and 3 on pages 6 to 8. Follow all other steps as usual.
Install the SMPTE 310M
6
interface card into slot 4.
Connect the IAB ribbon cable from
5
the MPEGscope main card to the optional line interface (e.g., the ASI & Serial ECL (DHEI) interface).
Remove the blank faceplate
2
and install the Real-time Analyzer card into slot 1.
Install the optional line
4
interface (e.g., the ASI & Serial ECL (DHEI) interface) into slot 2.
Connect the ribbon cable from
7
the MPEGscope main card to the Real-time Analyzer card.

Release Notes

Release Notes
This section describes two SMPTE 310M interface constraints that may affect your test. It includes a description of the problem along with a simple solution or workaround.
Initial startup with sparse streams
Large bit rate changes Because the SMPTE 310M interface implements a wide-band clock recovery
Upon initial startup or when you make a large bit rate change, the SMPTE 310M receiver may not synchronize if the stream contains large continuous strings of 1’s or 0’s. This could happen if you are receiving many NULL packets with an all-1 or all-0 payload (for example, from an idle SPI transmitter). You will notice many Rx Psync and Rx Clock errors from the SPI LIF dialog.
The problem occurs because the stream does not contain enough variation in bit values for the SMPTE 310M interface to unambiguously determine the bit rate. For example, it will not be able to differentiate a stream consisting of all 0’s at 40 Mb/s (where the bit has one transition) from a stream consisting of all 1’s at 20 Mb/s (where the bit has two transitions).
The solution is to play a stream that contains transport stream packets carrying real data until synchronization occurs. Without changing the bit rate, play the original stream again. The SMPTE 310M interface will remember the bit rate and correctly synchronize.
circuit, large bit rate changes (greater than 1 1/2 times the original rate) may cause the SMPTE 310M receiver to lose synchronization. For example, this could happen if you change from a bit rate of 22 Mb/s (with the interface correctly synchronizing) to a bit rate of 40 Mb/s. If this occurs, you will notice many Rx PSync and Rx Clock errors from the SPI LIF dialog.
You can avoid this situation by first changing to an intermediary value (for example, 30 Mb/s). Once the interface is in synchronization, increase the rate. Alternatively, you can disconnect the cable for a brief period, then reconnect it. The SMPTE 310M interface will achieve synchronization after a few seconds.
If the problem still occurs, you may be receiving large continuous strings of 1’s or 0’s. As described in the problem above, play a stream containing real data at the desired bit rate, then play the original stream again using the same rate. The SMPTE 310M interface will remember the bit rate and correctly synchronize.
