Getting Started

Table 1-7 summarizes the transport stream, network and peripheral device connectors; (see the MTM400 MPEG Transport Stream Monitor Technical Reference for more detailed information about each connector and the associated signals).

Connector

Description

 

 

Ethernet

10/100Base-T; RJ-45

LTC In

Longitudinal time code input

Transport Stream input /

75 ohm, transformer coupled, BNC connectors for the

output

following signal formats:

ASI input (BNC)

• Accepts Burst and Packet mode ASI formats and M2S

ASI output (BNC)

• An active loop-through of the corresponding input

SMPTE310M input

• Compliant with SMPTE310M (19.392 Mbps only)

SMPTE310M output

• An active loop-through of the corresponding input

Alarms

(Digital input/output) 26-pin D-type connector for alarm

 

relays and TTL outputs; also recording trigger input

The Alarms connector provides connections for five relays. Each relay is configured through the user interface (see Tests Screen, page 3-23 and Custom Screen, page 3-26); the three TTL outputs are configured in a similar manner.

ASI Loop-Through (QAM (Annex B), COFDM, 8VSB, and 8PSK only)

To monitor ASI and RF signals, (for example, both the input and output of a modulator):

ƒConnect the ASI signal from the modulator to the interface card ASI In.

ƒConnect the ASI Out terminal on the interface card to the ASI In connector on the Transport Stream Processor card.

Select the signal to be monitored from the configuration view (see page 3-76).

The ASI signal from QAM (Annex A and C) and QPSK (L-Band) interface cards is looped to the Transport Stream Processor card internally.
