Introduction

This is the Installation and Service manual for the Tektronix Multi-Channel Fiber (MCF) Series Video Transmission System. The manual is divided into sections identiﬁed and brieﬂy described as follows.

Section 1 — System Description and Speciﬁcations: A general intro-

■

duction about MCF. It includes a system description with physical specifications including weight, power requirements, and environmental and regulatory criteria.

Section

■ Section 2 — Installation: Installation procedures, including a func-

tional check after the physical installation.

■

Section 3 — Controls and Indicators: Descriptions and illustrations of the various controls and indicators found on the frame rear panel and on the front panels of the MCF modules.

■ Section 4 — Functional Description: A description of the major com-

ponents of the modules. It includes block diagrams.

■

Section 5 — Maintenance and Service: A description of the maintenance procedures, a troubleshooting table, and removal/replacement procedures for the MCF system modules.

System Description

The MCF Video Transmission System provides digital transport of full bandwidth video, and multiple channel audio over ﬁber. System architecture is modular, which allows channel growth by module addition. The MCF is a point-to-point unidirectional communications link with a transmit and a receive terminus.

MCF Installation and Service 1-1

Section 1 — System Description and Speciﬁcations

Two frame sizes are available—a 6 rack unit (RU) and a 2 RU. Each 6 RU frame requires a fan and deﬂector assembly. On the 2 RU frame the fan is installed in the frame and no deﬂector assembly is required. (See Section 2, “Installation,” for more information.)

The Audio and Video signals are formatted as follows:

■

Each Audio module (and the audio part of the Combined Video/Audio module) provides two stereo audio pairs (four channels) per video signal.

■ Each Video module (and the video part of any Combined Video/Audio

and Diplexer modules) provides one analog composite video channel.

■

Each Serial Digital module provides two AES/EBU serial audio interfaces and formats the video in either a 270 Mbs Component (D1) or 143 Mbs NTSC Composite (D2) serial video channel.

MCF Frames

Each Video/Audio Diplexer module provides monaural analog audio

■

(two channels), which is transmitted on FM subcarriers in the frequency band above the video.

On this and the following pages, you will ﬁnd information regarding the MCF frames (6 RU frame and 2 RU frame), the fan assembly, and the fan deﬂector assembly.

The MCF frame houses the control and signal processing electronics, power supplies, and the backplane. At the transmit end of the system, the frame is conﬁgured with a Fiber Transmitter module, Video Input modules, and Audio Input modules or any type of combined video and audio Input modules. At the receive end, the frame is conﬁgured with a Fiber Receiver module, Video Output modules, and Audio Output modules or any type of combined video and audio Output modules. Figure 1-1 shows how this works.

System Description

You can use either the 6 RU or 2 RU MCF frame as a repeater when transmitting over longer distances. The Repeater frame is located somewhere in the middle of the transmission link and uses a Fiber Receiver module to receive the signal and another Fiber Transmitter module to retransmit the signal. Adding an Output module here allows you to monitor (for troubleshooting purposes) the incoming signal with a Drop Monitor function. Figure 1-2 illustrates how this might look functionally.

System Description

A maximum conﬁguration (ten module slots) consists of one Fiber module and nine of the other modules. You can substitute one module of any of the video/audio combination modules (such as Serial/Digital) for the two Video and Audio modules. However, because there are only six time slots available, you can use only six combination modules. Serial digital and baseband analog video and audio signals can be mixed in the system as long as the six time slots are not exceeded. Serial digital requires one or two timeslots depending upon conﬁguration.

Fiber Modules

On the following pages, we discuss each of the frame components: Fiber modules, Video modules, Audio modules, Serial Digital modules, Video/

Audio Diplexer modules, power supplies, and the backplane.

Fiber modules can be used as transmitters, receivers, or repeaters. As a transmitter, the Fiber module transmits the MCF signal at the near end. As a receiver, the Fiber module receives the MCF signal at the far end. A repeater receives the MCF signal at one or more locations in the transmission link and then retransmits it again so it can be sent over longer distances. Refer to Section 1 of the MCF Operation Reference for more information about the different operations.

The maximum optical loss budget of a current MCF system is 23 or 29 dB when 0 dBm is launched. Fiber Transmitter modules operate in 1300 or 1550 nm wavelengths. Each Fiber module comes with FC/PC, SC, or ST connectors. Except for the ﬁber-optic connector on the front of the board, communication with the system passes through the backplane. The time slot interchange function found on these modules allows time slot manipulation for greater ﬂexibility.

It is also possible to drop signals for monitoring and distribution from either the Repeater or Receiver MCF frame.

See Table 1-7 on page 19 for a list of functional speciﬁcations.

MCF Installation and Service 1-9

Section 1 — System Description and Speciﬁcations

Combined Video/Audio Modules

The Video/Audio Input and Output modules consolidate the functions of

two MCF modules—they are the functional equivalent of the separate

Video and Audio Input and Output modules. Using these modules, up to six video and 24 audio channels can be accommodated in the MCF system’s 6 RU frame. In the 2 RU frame, up to two video and eight audio channels can be accommodated. MCF bus data for each module occupies one video and one audio time slot.

The following descriptions for the separate Video and Audio Input and Output modules are functionally the same and have more details. Refer to them if you need more information. Also see Table 1-7 on page 1-19 for a list of functional speciﬁcations.

Video Modules Input and Output

The MCF System bandwidth allows up to six video channels (one per module) to be transported over a single ﬁber. Video is digitized and halfband ﬁltered with a signal-to-noise ratio of >67 dB. Video is sampled at

31.054 MHz, which yields a ﬂat video passband maximum of approximately 6.89 MHz.

MCF is format independent—NTSC, PAL, and other video formats can be passed through these modules. Other video parameters are per EIA/TIA250-C Short Haul. Video and audio travel in separate time slots and are switched separately.

Audio Modules Input and Output

The MCF System bandwidth allows up to twenty-four analog baseband audio channels to be transported over a single ﬁber. Each audio module provides two stereo audio pairs, or four channels.

Audio channels are digitized at 18-bits. Current interfaces are discrete analog. Signal-to-noise ratio is approximately 90 dB. Other audio parameters are per EIA/TIA-250-C Short Haul, and ANSI T1.505.

Serial Digital Modules

The Serial Digital Input and Serial Digital Output modules are designed to provide component serial video at 270 MHz (D1) or NTSC composite serial video at 143 MHz (D2) and two AES/EBU serial audio interfaces to the MCF transmission system. The AES/EBU audio may be embedded in the serial digital video signal, or carried separately.

1-10 MCF Installation and Service

Audio uses two asynchronous stereo pairs. The audio input data clock is 48 kHz (± 400 ppm) for both audio inputs. Each channel can be independently enabled or disabled by software commands through the Fiber module.

Component (270 MHz, D1) serial video has a higher data rate that requires more bandwidth, so two time slots are required. The audio that goes along with the component video is not split between two time slots but is assigned to the primary time slot. NTSC composite (143 MHz, D2) serial video requires only one time slot.

See Table 1-8 on page 21 for a list of the video and audio performance speciﬁcations.

Video/Audio Diplexer Modules Input and Output

The Video/Audio Diplexer module occupies one MCF video time slot. The video carried in this module is baseband analog (see the previously described Video modules description for details). However, the audio is different. The Diplexer uses an audio-follow-video scheme to add subcarriers with video in a common time slot. This analog audio is not meant to replace digital audio—but to provide more channels. The audio input stage accommodates 600 Ohm balanced +18 dBm peak level signals.

System Description

Backplanes

Backplane for the 6 RU Frame

Audio subcarriers of 5.8 and 6.4 MHz are diplexed onto traditional TV1 video signals. The center frequencies of the FM subcarriers are ﬁxed at 5.8 and 6.4 MHz using slow feedback phase locked loops (PLLs). The peak-topeak deviation is 370 kHz at maximum modulation. The subcarriers are summed with the ﬁltered video at a relative level of –20 dBV (100 mV peakto-peak) per carrier.

See Table 1-7 on page 1-19 for a list of functional speciﬁcations and see Table 1-9 on page 22 for a list of the audio performance speciﬁcations.

The following text describes the attributes of the system in the 6 RU frame and 2 RU frame conﬁgurations.

Except for the ﬁber-optic cable connector and monitor connectors on the Video Input/Output modules, connections to the MCF 6 RU frame are made through the backplane. In addition to the communication connections, the backplane connector groupings for the 12 slots. Two are dedicated for power supplies and one for the Fiber module (either the Receiver or Transmitter). The remaining nine slots are used for combinations of video and audio type modules. Remember, you cannot mix input and output modules in the same frame.

MCF Installation and Service 1-11

Section 1 — System Description and Speciﬁcations

Each module connects to the backplane through two connectors. One connector is dedicated to analog interfaces. The second connector supports the internal communications bus. All video and audio type modules connect to this bus. On the rear of the backplane, each non-Fiber module has three BNC connections (two video inputs for loop-through, and one video I/O) and a screw strip connector for the two stereo audio pairs. Serial/Digital modules use the loop-through connectors separately (loop-through disabled) for I/O monitoring. Figure 1-9 illustrates the 6 RU backplane.

Pre-Installation Planning

Some preplanning is required before installing your MCF system. The following paragraphs describe speciﬁc items you need to address.

MCF Installation and Service 2-1

Section 2 — Installation

Calculating Optical Fiber Path Loss Budget

Before installing your equipment it is important to calculate the optical loss budget, which determines the amount of optical energy available at the MCF Receiver unit. If the energy is too low, the noise ﬂoor rises and causes excessive bit error rates. If the energy is too high, the Receiver’s optical detector will be overdriven and cause excessive bit error rates.

To achieve speciﬁed performance in your current MCF system, the optical power arriving at the receiver must be greater than –23 dBm (or -29 dBm on recently-produced receiver boards) and less than –10 dBm (that is, between –10 dBM and –23 dBm), as measured with an optical power meter. The received power equals the difference between ﬁber path losses in your facility and the output power transmitted into the ﬁber.

Output Power Transmitted = + 0.0 dB Fiber Path Loss = –20.0 dB Receive Power = –20.0 dB

If the received power exceeds –10 dBm (typical on very short ﬁber paths), a ﬁxed value optical attenuator can be inserted into the ﬁber path. To calculate your system’s total optical ﬁber path loss budget, see the following example.

The total ﬁber path loss budget possible with the MCF system is 23 dB (or 29 with recent-production receivers) calculated according to the following formula:

Device Loss Budget Allowance

9 µm Singlemode (1300nm) Cable 0.5 dB per kilometer FC/PC Singlemode Connector 1.0 db per connector Singlemode Splice 0.5 dB per splice

Note Manufacturer’s speciﬁed connector and splice losses are typically less than

those shown here. These losses are intended for use in Loss Budget calculations and, therefore, include allowance for degradation.

This example illustrates a ﬁber path loss budget calculation:

25 km single mode ﬁber @ 0.5 dB per kilometer = +12.5 dB Four FC/PC connectors @ 1 dB per connector = + 4.0 dB Ten splices @ 0.5 dB per splice = + Total loss budget = +21.5 dB

This loss budget is within the range of the MCF system (between 0 dBm and

–23 (or -29) dBm).

For output power of the optical transmitter, refer to the speciﬁcation table found in Section 1 of this manual.

5.0 dB

2-2 MCF Installation and Service

Space Planning

The MCF system installs in a standard 19-inch equipment rack where a rack unit (RU) equals 1.75 inches (44.5 mm). The large MCF frame occupies 6 RUs and the required fan and deﬂector assemblies occupy 1 RU each for a total of 8 RUs. (See the following subsection, “Installation of the MCF system in the Equipment Rack,” for additional information.) The small MCF frame occupies 2 RU. The 2 RU frame exhaust fan is inside the frame. No additional fan or deﬂector assemblies are required, so the overall frame height is 2 RUs.

Power Requirements

For DC operation, a –48 volt supply is required. For AC operation, nominal line voltage of 120 or 240 volts, 50–60Hz is required. The 6 RU frame AC operating voltage is selectable (110/220 VAC) via a switch at the rear of the frame. The 2 RU frame is self-selecting. (See the following “Power Connection” subsection for additional information.)

Pre-Installation Planning

Heat Considerations

The MCF system operates in an ambient temperature range of 0° to 50° C.

Humidity

This equipment operates within an ambient non-condensing humidity range of 0% to 95%.

MCF Installation and Service 2-3

Section 2 — Installation

Unpacking the Equipment

Follow the steps given here and on the following page as you unpack the Tektronix equipment.

Receiving Inspection

Inspect all shipping containers for any signs of damage. If any damage is found, notify the shipping company immediately.

Unpacking

Follow the safety precautions found in Steps 1 through 4 when unpacking the Tektronix equipment.

1. Place the shipping containers on a ﬂat, level surface with enough room

to move the containers around as needed.

2. Locate the shipping container with the small plastic pouch and remove

the Packing List.

CAUTION When handling the Fiber Transmitter and Fiber Receiver, avoid unnecessary

handling of the ﬁber pigtail and connector which can be broken or damaged by improper handling. Damage due to mishandling is not covered by warranty.

3. Open the shipping containers, carefully remove the contents, and place

the contents on a ﬂat, level surface.

4. Compare the contents in each shipping container with the packing list

to ensure there are no missing items. Make notes of any discrepancies.

For a single 6 RU system, each terminus should have a

■ Frame

■ Fan Assembly

■ Deﬂector Assembly (identical to the fan assembly but lighter as it does

not have the fans)

For multiple 6 RU frame systems mounted in a telco-rack, separate deﬂector assemblies are not required.

The 2 RU frame system is entirely self contained. No fan or deﬂector assemblies are included.

If there are any discrepancies between the packing list and items received, contact Tektronix Customer Service.

■ Connectors for bent or broken pins

■ Cables for crimped or broken wires

■ Glass ﬁbers for breaks and kinks

■ Equipment chassis for any visible damage

If any damage is found, contact Tektronix Customer Service.

Note If an item is damaged, DO NOT make any power or signal connections unless

otherwise advised by Tektronix Customer Service.

Test Equipment and Tools Required

No speciﬁc test equipment required for the initial installation and setup of your MCF system. A ﬂat-blade and cross-head screwdriver are the tools required to complete the installation.

Installation of a 6 RU Frame in the Equipment Rack

The 6 RU frame installs in a 19-inch (483 mm) equipment rack. A wider 23inch (584 mm) rack can be used with an optional 23-inch mounting bracket kit (part number MCF-BRK-236). Figure 2-1 illustrates installation of a

AC Power Connections

The AC power connections for the 2 RU or 6 RU frame are slightly different. Those difference are noted in the following text.

Six RU Frame

AC power may be connected to either J3 or J4 or both, depending on your MCF system conﬁguration. Setting the line (source) voltage level is done with either S1 or S2, or both, again depending on whether you have a redundant power supply installed. Figure 2-10 illustrates the location of S1 and S2. To connect AC power, see Figure 2-5 (for location of the AC connector on the backplane) and Figure 2-10 (for S1 or S2 location), and perform the following steps:

CAUTION Set S1 and/or S2 only when the AC power source is disconnected. Changing

the setting with the AC power connected causes catastrophic damage to your MCF system.

1. Using a small, regular screwdriver, set the Line Voltage

Selector Switch, S1 and/or S2, as shown in Figure 2-10, to the correct level of AC source power (110 or 220 Volts nominal).

Making Power Connections

2. Attach the socket (female) end of the supplied power cord(s) to the AC

The RS-485/RS-232 ADMIN PORT connector (J01 on the 6 RU frame, and J12 on the 2 RU frame) is a DB-25F socket connector. This connector connects the frame to a computer. A commercially available 25-pin, null modem cable may be used for the RS-232 application; however, the RS-485 cable must be constructed. The pinouts for both cables are listed in Table 2-2.

RS-485 Communication

To preserve the shape and integrity of a waveform traveling along a cable, the cable must be terminated in an impedance equal to its characteristic impedance. In a system such as this, where data travels in both directions, both physical ends of the cable must be terminated into a 120 Ohm impedance. Stubs leading to each Transmitter should be as short as possible. Circuit ground of all transmitters must be connected via a dedicated wire within the cable.

Leaving off the terminations generally results in reﬂections that can have amplitudes of several volts above V and undershoots can disrupt the Transmitter operation, create false data, and in some cases possibly damage components on the bus.

Serial Digital Video Connections

Using the Serial Digital module’s video connections when on the 6 RU frame require that you use the lower Video I/O BNC connectors (I/O 1 through 9), not the loop-through connectors (IN 1 through 9). However,

2-28 MCF Installation and Service

connectors IN 1–9 can be used one at a time (not as loop-through) for I/O monitoring. See Figure 2-24 to see where the Video I/O connectors are located.

On the 2 RU frame, when using a Serial Digital module, video connections use J1 and J4. Connectors J2-J3 and J5-J6 can be used for I/O monitoring. (Not as loop-through).

Incompatible Systems

Recent production MCF Transmitters operate in two modes: Non-return to zero (NRZ) and non-return to zero, inverted (NRZI). Earlier-generation MCF Transmitters operate in NRZ mode only. Depending on when they were manufactured, some MCF Receivers operate only in NRZ mode while others operate only in NRZI mode. See the following two paragraphs and Table 2-5 for a quick reference on compatibility of various transmitter and receiver pairs. Also see Table 2-6 for similar data with greater detail on board modiﬁcation and NRZ versus NRZI modes of operation.

The following systems are incompatible:

■ A new 160293-00 Transmitter (set to NRZ mode) or 160293-01 with an

old 066040 -00, -01, -10, -20, -21 Receiver.

Section 2 — Installation

Audio Connections

The actual number of connections depends on your system conﬁguration.

The DC Restore function should be enabled by placing jumper J16 (located on the Video Output module) in the ON position. This is the factory default setting.

Also see the Video module cable equalization information in the text that follows.

Note that the MONITOR connector on the front panels of the Video modules may be used to connect a monitor. On a Video Input module, this monitor can be used to check the video coming in at the backplane. On a Video Output module, it can be used to see the video being decoded on the Fiber module.

Audio connections are available for four channels (A, B, C, and D) with stereo pairs A/B and C/D. These connectors can also be used for AES/EBU audio bit streams, with a few limitations, when using Serial Digital modules in the frame.

Connecting audio to the MCF frame is a two-phase operation. The ﬁrst step is insertion of audio leads into a mating connector. Each connector accommodates twelve leads, three for each channel. The second step is installing that connector with leads attached to the appropriate pins at the rear of the MCF frame.

Audio Clip Level

Each MCF system has user-selectable Audio Input and Output signal levels. These levels are adjusted by turning the gain adjustment potentiometer and viewing the Clip and Quiet LED indicators located on the front of the modules.

The LED indicators at the front of the Audio Input and/or Output module signify excessive input or output signal levels that result in signal distortion. If a clip indicator is illuminated only occasionally or momentarily, no action is required. If clipping is continuous, the input/output signal should be attenuated or the gain reduced. If the desired headroom is +16 dB, the desired clip level calculation would be as follows:

Nominal Input = + 8 dBm Desired Headroom = +16 dB Clip Level Setting = +24 dBm

MCF Installation and Service 2-39

Section 2 — Installation

Set the front panel clip level by rotating the switches located on the front of the module. See Figure 2-34. Refer to page 2-63, for more detailed information about setting clip levels.

Section 2 — Installation

Craft Port Parity and Baud Rate

The following text describes how to set up the two DIP switches.

Craft port conﬁguration is accomplished by setting its baud rate and parity through DIP switch S2 on the Fiber Transmitter and Receiver modules. The DIP switch location on both Fiber modules is illustrated in Figure 2-37.

Craft Port Baud Rate & Parity Switch

Figure 2-37. Craft Port Baud Rate and Parity DIP Switch on Either Fiber Module

Both the baud rate and parity are set on the Fiber Transmitter or Receiver module using the 8-segment DIP switch S2, where segments 1, 2, and 3 are used for baud rate selection and segment 4 is used for parity.

Figure 2-38 illustrates DIP switch S2 with all possible baud rates and the positions of the switch segments. Table 2-7 on page 2-43 lists the positions of S2 with the various baud rates available.

Note that 9600 baud is selectable with segments 1, 2, and 3 all set to Open (Off) or all set to Closed (On).

Transmitter or Receiver Frame Address

Each MCF frame must have a unique address assigned from 0 (zero) to 255. This frame identiﬁer is set on the Fiber Transmitter and Receiver modules. Switch S1 is an 8-position DIP switch used to set the address for the MCF frame within which the Fiber module resides. Figure 2-39 illustrates the location of S1 on the Transmitter or Receiver module.

Transmitter or Receiver Frame Address Switch

Figure 2-39. Frame Address DIP Switch

Each segment of the DIP switch has a numeric (binary) value. The left side of Figure 2-40 illustrates the numeric value for each segment on the DIP switch, and the right side illustrates an example of a speciﬁc address. In the example shown, frame address 83 is selected. Selections are made by setting the desired switch segment to the appropriate Closed (On) or Open (Off) position. So, you may assign any address number (between zero and

255) by turning on or off different binary switch combinations.

Video Input and Output Module Settings

Various jumper selections on the Video Input and Output modules are required for proper system operation:

■ Cable Equalization Selection

■ External or Internal Video Termination (75 Ohm)

■ Video Signal Squelch

■ DC Restore

The following text describes how to select these settings.

Cable Equalization

A Video module may need cable equalization to compensate for cable length. Each Video module has an equalization (EQ) potentiometer on the front panel which may be adjusted for this compensation. Adjustment preequalizes from an Output module or equalizes from an Input module. Measurement is taken with a waveform monitor at the front panel MONITOR connector for a Video Input module and at the backplane VIDEO I/O connector for a Video Output module.

The EQ potentiometer is enabled/disabled by a jumper at either J10 (on a Video Input module) or J14 (on a Video Output module). See Figures 2-43 and 2-44 for jumper locations on the modules. If equalization is ﬂat (no equalization necessary), EQ is disabled by installing the jumper block across positions one and two. This setting is the factory default. To enable EQ, install the jumper block across positions two and three.

If cable equalization is required, it will be necessary to install one or two Hybrid Equalization boards, depending on the cable length, and to change and/or add a jumper block on the affected module. Hybrid Equalization

modules must be ordered separately, as needed. See Table 2-8 on page 2-47.

Video Input Module Cable Equalization

Cable equalization is attained by installing the Hybrid boards U29 and U37 and setting up the jumper block at J9 on the Video Input module. Cable length determines whether one or two Hybrid boards need to be installed and also determines the position of the jumper block. Lengths of 0–500 feet require one board and lengths of 500–1000 feet require both Hybrid boards. In addition, the Hybrid boards are video cable I.D. speciﬁc. See Table 2-8 on

page 2-47 for speciﬁc cable model numbers.

For a Video Input module, Figure 2-43 illustrates the locations of the EQ jumper J10, the Hybrid board plug-ins, and the Hybrid boards’ jumper, J9.

Table 2-8 on page 2-47 lists the Hybrid boards by cable I.D. for U 37 (0–500

feet) and U 29 (500–1000 feet).

Video Output Module Cable Equalization

Cable equalization is attained by installing the Hybrid boards U28 and U29 and setting up the jumper block at J12 on the Video Output module. Cable length determines whether one or two Hybrid boards need to be installed and also determines the position of the jumper block. Lengths of 0–500 feet require one board and lengths of 500–1000 feet require both Hybrid boards. In addition, the Hybrid boards are video cable I.D. speciﬁc. See Table 2-10

on page 2-66 for speciﬁc model numbers.

For a Video Output module, Figure 2-44 illustrates the locations of the EQ jumper J14, the Hybrid board plug ins, and the Hybrid boards’ jumper, J12.

Table 2-10 on page 2-66 lists the Hybrid boards by cable I.D for U28 (0–500

feet only) and U29 (500–1000 feet).

For the following procedure, refer to Figure 2-43 and Table 2-8 on page 2-47 for a Video Input module and to Figure 2-44 and Table 2-10 on page 2-66 for a Video Output module. Install equalization Hybrid boards and jumper blocks per the following steps:

CAUTION This equipment contains static sensitive components. Use anti-static

grounding equipment whenever handling modules and components. When circuit modules are removed from the frame, place them on a ﬂat static-controlled surface. Failure to follow this precaution can result in component damage due to electrostatic discharge.

1. Remove the appropriate Video Input/Output module and place on a

ﬂat, level, static-free surface with the orientation as shown in either Figure 2-43 or 2-44.

2. To enable the EQ potentiometer on either J10 (for the input module) or

J14 (for the Output module), move the jumper from pins 1 and 2 and place it over pins 2 and 3. (See either Figure 2-43 or 2-44.) If no Hybrid is to be installed, skip to Step 5. Otherwise, proceed with Step 3.

Video Input and Output Module Settings

3. Install the Hybrid(s) appropriate to the Video I/O module and cable

type. (See the tables and ﬁgures in previous text for correct Hybrid location and Hybrid part number.) Note that the Hybrid board is installed with Pin 1 toward the top of the module as illustrated in Figure 2-45.

Video Signal Termination

To preserve the shape and integrity of a video waveform traveling along a cable, the cable must be terminated in an impedance equal to its characteristic impedance. In the MCF system, the physical ends of the video cable must be terminated with a 75 Ohm resistor. Leaving off the terminations generally results in poor video signal operation. If loop-through video operation is desired, termination is not required.

Video Squelch Jumper

When no video signal is present, the MCF Receiver module outputs a high level of unquieted noise. Because this is not desirable, squelch circuitry can blank the video output. Refer to Figure 2-47 for the location of the video

DC Restore Jumper

The MCF system’s DC restoration circuitry provides a slow return of the base level of the video signal to a ﬁxed DC reference voltage. Due to the design of DC restore circuitry, rapid corrections of the video signal are not possible. However, the signal’s DC component is restored without introducing the distortion caused by clamping.

Both the Video Input and Output modules have DC restoration circuitry, and you must set jumpers on both modules to enable the DC restore operation. See the following text for details.

When the jumper is set to ON, the MCF system’s DC restoration circuitry provides a slow return of the video input signal to a ﬁxed DC reference voltage. Figure 2-48 illustrates the location of jumper J13 on the Video Input module.

Audio Input Module Setting

The Audio Input module has a single jumper setting—audio input attenuation. The following text describes this jumper setting and jumper location.

Input Audio Attenuation

The MCF system is designed with an audio gain of unity into a 600 Ohm impedance load. However, your facility may require a different setting. The input impedance may be changed from 600 to 150 Ohm or HIGH Ohm (30 Kowloon differential) impedance (for bridging applications).

To set jumpers J7, J8, J9, and J10 on the Audio Input module, follow the steps listed below:

1. Remove the Audio Input module from the frame, and place on a ﬂat,

level, static-free surface with the module orientation as shown in Figure 2-50.

Audio Input Module Setting

2. Select the appropriate impedance jumper settings for Channels A (J7),

B (J8), C (J9), and D (J10).

3. Reinstall the module into the frame and resume operation.

5171-215

If cable equalization is required, it will be necessary to install one or two Hybrid Equalization boards (depending on the length) and to change and/ or add a jumper block on the Input module.

Cable equalization is attained by installing the Hybrid boards, U61 (0-500 feet) or U65 (500-1000 feet) and by setting up the jumper block at J21. Refer to Figure 2-51 for the equalization hybrid board plug-ins and jumpers J14 and J21 locations.

Whether one or two Hybrid boards need to be installed and the position of the jumper block depends on the cable length. Lengths of 0–500 feet require one board and lengths of 500–1000 feet require both Hybrid boards. In addition, the Hybrid boards are video cable I.D. speciﬁc by length.

Table 2-8 on page 2-47 gives speciﬁc cable model numbers.

Output Cable Equalization

A Video/Audio Output module may need cable pre-equalization (video only) to compensate for your cable length. Each Video/Audio Output module has an equalization (EQ) potentiometer on the front panel which may be adjusted for this compensation. The adjustment pre-equalizes the video output. Measurements are taken with a waveform monitor at the backplane VIDEO I/O connector.
