DS1000 Series User Manual 1–1

Getting Started

By applying an RF signal to the antenna input, the television demodulator provides baseband video and audio outputs and IF output signals.

You can set tuning conditions for stored programs, which are held in non-volatile memory. Tune the signal by channel, frequency, or preset program. Twenty presets can be stored and recalled with different configurations.

Most instrument functions are controllable through the remote serial interface. Connection is through the SERIAL connector (9 pin) on the rear panel. The interface type, RS232C or RS485, is configured through the Serial Config menu. With the RS485 protocol, you can set unique addresses for multiple units and control them all remotely.

Physical Dimensions

The dimensions of the television demodulator are length 1.8 inches

(46 mm), width 8.1 inches (206 mm), and depth 17.3 inches

(440 mm). In a 19 inch (483 mm) rack, it is a half rack wide by one rack unit high.

Options

You can purchase the television demodulator with several options and accessories. Table 1–1 lists the power cord options.

Getting Started

Electrical Installation

Before proceeding with product installation, please read the Safety

Summary at the front of this manual.

NOTE . Save the shipping carton and packing materials in case it becomes necessary to ship the television demodulator to a Tektronix

Service Center for service or repair. Packaging instructions are on page C–1.

AC Power Source

The television demodulator operates from an AC source with a line voltage in the range 95 to 240 VAC and with a line frequency of 50 or

60 Hz.

The television demodulator is designed to operate from a single-phase power source having one of its current-carrying conductors at or near earth ground (the neutral conductor). Only the line conductor is fused for over-current protection.

Systems that have both current-carrying conductors live with respect to ground (such as phase-to-phase on multiphase systems) are not recommended as power sources. A protective ground connection by way of the grounding conductor in the power cord is essential for safe operation.

Changing the Mains Voltage

The unit is designed to operate over the specified range (95 to

240 VAC) without the need for adjustment.

Power On Procedure

To power on the television demodulator, connect it to the AC power source. There is no power switch. See Figure 1–1. The power on sequence completes in about 10 seconds.


Getting Started

The television demodulator tests major circuits during power on and displays the following status messages:

ROM test

RAM test

I 2 C test

System Initialization

When testing completes, the television demodulator displays the current RF setting.

DS1000 and VM100 series instruments side by side.

TVGF14 adapter mounts two half-rack width instruments vertically in a standard 19-inch rack. Use this adapter to mount

DS1000 and VM100 series instruments with a 1700 series monitor.


Getting Started

Functional Check

To check that the television demodulator is operating correctly, perform the following procedures:

1. Connect the television demodulator to power and wait a few seconds for the power-on tests and initialization. If these tests pass, the display will show the current frequency/channel setting.

2. Apply an RF signal feed from an appropriate television standard for your model of television demodulator to the RF input. Use a

75

W

coaxial cable. The RF source should match the current frequency/channel setting. If not, refer to the Operating Basics section for information on selecting a new frequency/channel.

3. Connect the video output (VIDEO O/P) either to a picture monitor, waveform monitor, or other monitoring equipment. Ensure that this connection is terminated in 75

W

.

4. Check for a valid video display and, if possible, a nominal 1 Vpp signal level.

5. Connect the audio outputs (AUDIO OUT R and AUDIO OUT L) to a suitable audio monitoring device. For example, use the Lindos

LA102 Audio Measuring Set. Check for a nominal 0 dBm level.

6. Connect the IF output (45.75 IF on the DS1001 model or

38.9 MHz on the DS1002 and DS1003 models) to a 100 MHz oscilloscope terminated in 75

W

.

7. Check for a modulated RF signal at 45.75 MHz.

8. Connect the 4.5 IF output (DS1001 model only) to a 100 MHz oscilloscope terminated in 75

W

.

9. Check for a nominal 700 mVpp (+48 dBmV) signal.

This concludes the functional check. If your television demodulator failed any check in this procedure, review your connections, terminations, and instrument settings. A continued failure may indicate the need for repair. Contact your service person or a

Tektronix, Inc field office for assistance.




The DS1000 Series Television Demodulators are typically used as part of a system that includes video and audio measurement equipment, such as the Tektronix VM100 Series Automated Measurement Set.

Typical equipment connections are described in the Functional Check procedure on page 1–8 and are shown in Figure 1–2 on page 1–6.

The television demodulator configuration system allows the store and recall of system settings through the use of programs (presets). All program settings are saved in the television demodulator non-volatile memory when the unit is turned off.

The following procedures use factory settings for the illustrations; your display will vary if you have changed the settings.

Operating Procedures

This section describes how to correctly apply power to the television demodulator and how to operate the instrument.

Applying Power

1. Apply an appropriate mains power source to the television demodulator through the supplied power cord. There is no power switch.

2. The front panel LCD briefly displays the starting self-test message before starting the self-tests. Each of the self-tests displays a different test message. If any of the tests fail, a test failure message appears and the unit waits for you to press a button before it continues with the remaining tests.


Operating Basics

Once the self-tests complete, the unit initializes itself, which takes about 1 second to perform if the internal non-volatile memory is valid.

If the memory has been corrupted or damaged, then the television demodulator will attempt to load factory default settings. This process takes 5 to 10 seconds. When the initialization sequence completes, the unit displays the current channel/frequency selection along with the RF signal strength.

Selecting Display Modes

To access the display modes for the television demodulator, press the

DISPLAY button on the front panel. Each press of the display button accesses the next display mode. When you reach the last display mode, the next press of the display button returns the display to the first display mode. The following list describes the display modes in their order of appearance:

1. System Status.

After power on sequence completes, the display shows the current channel and frequency selection and the RF signal strength for the channel and frequency.

The channel number is taken from the frequency table you select.

It may be either numeric or alphanumeric depending on its definition in the frequency table.

If the frequency does not correspond to a channel frequency in the current frequency table, then the channel number is replaced by asterisks.

The RF signal strength is displayed in the form of a bar graph and represents the signal strength for the current channel frequency. A weak signal (RF amplitude < 100 m

V) is represented by 10 dashes

‘–’ on the bar graph. As the signal strength increases in amplitude,


Operating Basics the dashes are replaced by blocks ‘

J

’ from the left, until all dashes have been replaced (RF amplitude > 1 mV).

2. Audio Output Status.

The audio output display shows the current status of the audio signals on the XLR connectors located on the rear panel.

3. Program Set-up.

The program set-up display allows you to view the configuration of the current program (preset). The top line shows the active program number and the bottom lines shows the program items.

Use the up and down buttons (

↑

and

) to view the entire configuration by scrolling through the various program items.

Refer to page 3–3 for a description of each item in the Program set up.

To change a Program, select the Program number here, then press the CONFIG button. Refer to Program Configuration on page 3–3 for further instructions.

4. NICAM Error Count (PAL systems only).


Operating Basics

The error count gives the number of NICAM errors per 128 ms period. Three versions of the error count are displayed:

Av – Average error count shows the average number of errors over the last ten readings.

Pk – Peak error count shows peak errors and delays while the error count is less than the displayed peak error count.

Ph – Peak hold error count shows the maximum error count. It is updated if the latest error count exceeds the current peak hold error count.

All three error counts can be cleared by pressing the enter (

↵

) button when in the Nicam error count display mode.

5. Product title.

The product title display shows the product number, transmission standard and unit serial number.

The frequency range is 45.25 MHz to 860.25 MHz in 0.25 MHz steps.

If the selected frequency corresponds to a standard channel, then that channel number appears in parentheses. Otherwise, asterisks appear in place of the channel number. This frequency selection


Reference and the previous channel selection interact. Changing either one will change the other.

4. ZCP.

The zero carrier pulse (ZCP) is a special feature of the television demodulator. You configure the ZCP feature using the ZCP status,

ZCP line, and ZCP position items.

The ZCP status item determines whether the ZCP signal is on or off.

OFF ON

The ZCP line setting determines on which video line the ZCP is active. For PAL systems the line number range is 6 to 16 and

319 – 329. For NTSC systems the line number range is 10 to 20

(F1) and 10 to 20 (F2).

The ZCP position item determines the start position of the ZCP on the chosen video line. The five position choices are 0 to 4.


Reference

5. Audio Preference.

For NTSC systems, the audio preference is set to BTSC with no other options.

Reference

Frequency Response Configuration

In the television demodulator system there are two levels of frequency response adjustment. The first is factory set and cannot be adjusted from the front panel. The second is the manual frequency response item which allows minor adjustments to the frequency response.

Use caution when changing the manual frequency response and do so only when connected to equipment that can measure the changes to frequency response.

The changes to frequency response affect only the current active frequency, which is shown on the top line of the frequency response configuration display. You can adjust several frequencies which are stored in the television demodulator non-volatile memory.

Due to memory limitations within the television demodulator, it is impractical to store frequency response adjustments for every possible frequency, so the adjustments are possible only for the range of frequencies listed in Table 3–2.

Programming Model

The television demodulator uses the BCP Simplified Communication

Link protocol (SCL). With the SCL Protocol, you program a PC to send and receive data using standard I/O functions found in most programming languages, such as C, PASCAL, and BASIC.

The SCL protocol supports asynchronous binary communication, not text or ASCII based. Communication is based on 8-bit bytes ranging from 0 to 255. Table B–2 lists special byte codes used to coordinate data transfers between the PC and the television demodulator. For information on how to use these special byte codes, refer to Sending

and Receiving Data on page B–5.

Addresses on page B–3.

Addresses

The television demodulator has four addresses that are necessary for communication using the SCL protocol. Table B–2 lists the four addresses: Ad, Ar, Ars, and Arr. For information on using these



B–4 addresses, refer to page B–5. The addresses perform the following functions:

Device address (Ad) is set to 0F hex in all television demodulators.

The PC uses the device address to initiate communication with a television demodulator.

Remote address (Ar) is unique for each television demodulator.

You set this unique address as a decimal number. To set the address, use the SERIAL SET–UP item in the configuration menu.

The remote address is the base address used to determine the Ars and Arr addresses.

Send remote address (Ars) is used to send data to the television demodulator. Calculate Ars using the following equation:

Ars = Ar x 2

Receive remote address (Arr) is used to receive data from the television demodulator. Calculate Arr using the following equation:

Arr = Ar x 2 + 1

For example, if you set the remote address (Ar) to 50 decimal

(32 hex), its SCL protocol addresses are as follows:

Ad (from Table B–2) = 0F hex

Ars = (32 hex) x 2 = 64 hex

Arr = (32 hex) x 2 + 1 = 65 hex

Remote Operation Flag

Some commands can be used only when the television demodulator is in the remote controlled state. When in remote control state, you cannot control the television demodulator from the front panel. The front panel display indicates the remote control state with the message

“REMOTE CONTROLLED”

Two commands control the state of the remote flag. Use the command

PWD= to enter the remote control state and set the remote flag to true (1). Use the DISC= command to resume front panel control and set the remote flag to false (0). Use the LOG? query to get the current state of the remote flag.



Command Types

There are two types of commands.

Select commands end with an equal sign (=), such as “PRESET=”.

Select commands set the television demodulator to operate in any mode allowed from the front panel.

Query commands end with a question mark (?), such as “PRE-

SET?”. Query commands tell the television demodulator to prepare to send a particular type of data to the PC.

Commands may be followed by one or more parameters specific to the command. Parameters are in binary format. Query commands often do not require parameters. The response data from a query command may contain several parameters.

For information on the syntax used for command definitions, refer to page B–11. The alphabetical list of commands and their parameters begins on page B–13.

Sending and Receiving Data

The PC must send commands and addresses in a certain order when writing data to and reading data from the television demodulator. The main steps in the communications process are as follows:

1. Send the identifying addresses.

2. Detect readiness of the television demodulator.

3. Send command and parameters.

4. Receive response/data.

Several types of communications are possible. Each type has a pattern of commands or phases that must be used. The following discussions introduce these communication phases: send address, send data, receive address, poll for messages, and get messages.

Send Address Phase

The PC uses Ad and Ars to address a particular television demodulator. The television demodulator configured with a matching address answers with either a ready response or a not ready response. Sending



B–6 this address data aborts all other communication on the bus. The following three cases show variations of the send address phase.

The PC addresses a television demodulator that is not ready to receive data:

Addressing phase

Not ready response

The PC addresses a television demodulator that is ready, and the PC sends data:

Addressing phase

Ready response

Data phase

The PC addresses a television demodulator that is not ready, ignores the not ready response, and sends data:

Addressing phase

Aborted ready response

Data phase

The PC can ignore the not-ready response and transmit the addressing phase and data phase sequentially. In this case, the television demodulator aborts the not ready response after receiving the first byte of the data phase. The PC receives only a DLE character.

When sending data, Ad and Ars can be replaced by FF hex, a broadcast address. When the television demodulator sends a ready response, it will send its real address. You can use this broadcast address to determine the address of a television demodulator. The wild card remote address is always a send address phase.

Send Data Phase

The send data phase begins with a command and may be followed by one or more parameters specific to the command. Two techniques for sending data are possible.

The PC addresses a television demodulator that is ready and sends data:

Addressing phase



Ready response

Data phase

The PC addresses a television demodulator that is not ready, ignores the not ready response, and sends data:

Addressing phase

Aborted ready response

Data phase

The PC can ignore the not-ready response and transmit the addressing phase and data phase sequentially. In this case, the television demodulator aborts the not ready response after receiving the first byte of the data phase. The PC receives only a DLE character.

If the byte 10 hex is part of the data, this byte is sent twice so that it is not confused with DLE ETX (10 hex), which ends the data phase.

Receive Address Phase

To acquire data from the television demodulator, the PC first sends the

Ad and Arr addresses to identify the television demodulator. This address phase aborts other communication on the same bus. The television demodulator responds with a not ready phase if it does not have the requested data. It responds with a ready phase followed by a data phase when it has data. The receive data phase contains the Ad and Arr addresses to identify the responding television demodulator.

Examples of receive communication between the PC and the television demodulator follows with descriptions in italics.

The PC addresses a television demodulator that has no data available:

Addressing phase

Not Ready response

The PC addresses a television demodulator that has data available, and the television demodulator returns the data:

Addressing phase

Ready response and data phase



B–8

If the byte 10 hex is part of the data, this byte is sent twice so that it is not confused with DLE ETX (10 hex), which ends the data phase.

Polling for Status Messages

If a television demodulator has a message, it does not send it to the

PC, because more than one television demodulator can be connected to the same remote interface bus. To avoid data contention, the PC uses polling to check for messages.

Polling is done with the PATH? command. PATH? returns an empty string if the television demodulator has no message, and returns the path if a message is available. The path contains the addresses Ad and

Ars (see Addresses on page B–3).

The following example is one continuous polling communication between the PC and the television demodulator. The values for Ad,

Ars, and Arr can be calculated according to instructions on page B–3.

The PC addresses a television demodulator that is busy, repeats the addressing phase until the television demodulator returns a ready phase, then the PC sends the “PATH?” command.

PC > [DLE] [ENQ] [Ad] [Ars]

DS1000 >[DLE] [WACK]


Send Addressing phase

Not Ready response


DS1000 > [DLE] [ACKO] [Ad] [Ars]

Ready response

PC > [DLE] [STX] ['PATH?'] [DLE] [ETX]

Data phase

After receiving the PATH? command, the television demodulator places its answer in its transmit buffer. The PC tries to retrieve the message with a receive cycle, but the television demodulator has not processed the answer yet.

PC > [DLE] [ENQ] [Ad] [Arr]

Receive Addressing phase

DS1000 > [DLE] [WACK]

Not Ready phase

The PC repeats the addressing phase until the television demodulator is ready and transmits its data phase. There is no data included, because the television demodulator has no message.





DS1000 > [DLE] [STX] [Ad] [Arr] [DLE] [ETX]

Data phase

The PC continuously polls the television demodulator.




Ready phase

PC > [DLE] [STX] ['PATH?'] [DLE] [ETX]

Data phase



The television demodulator responds with data when it has a message.

The [data] is the path, Ad Ars, which indicates that a message is available from the responding television demodulator.

DS1000 >[DLE] [STX] [Ad] [Arr] [data] [DLE] [ETX]

Data phase

Getting a Message

Polling a television demodulator only tells the PC if a message is available. To receive the message, you must use the MSG? command.

The following example shows how to use the MSG? command to retrieve a status message from a television demodulator.

The PC addresses a television demodulator that is busy and repeats the addressing phase until the television demodulator returns a ready phase. The PC then sends the “MSG?” command.

PC >[DLE] [ENQ] [Ad] [Ars]



Ready phase

PC > [DLE] [STX] ['MSG?'] [DLE] [ETX]

Data phase

After receiving the MSG? command, the television demodulator places its answer in its transmit buffer, and the PC retrieves the message with a receive phase. The data in this example (20h) is the test message. Other bit patterns are listed with the MSG? command.


Receiving addressing phase

DS1000 > [DLE] [STX] [Ad] [Arr] [20h] [DLE] [ETX]

Data phase



The PC acknowledges the data by sending the MSG= command followed by the data bit pattern. The PC resumes polling, but clears the message data as it reads the message.

Appendix C: Service

WARNING.

To avoid personal injury or damage to the unit, be sure that the power is not supplied to the television demodulator while performing the procedures in this section.

This section contains instructions for user service and preventative maintenance. The only serviceable part is the fuse, which is available on the rear panel.

There are no user serviceable parts within the unit. Please return it to a

Tektronix Service Center for service and calibration.

Packaging for Shipment

If it becomes necessary to ship the television demodulator to a

Tektronix Service Center, follow these instructions:

1. Write the following on a tag attached to the product: the product owner, complete address and phone number of someone at your firm who can be contacted, the product serial number, and a description of the required service.

2. Package the product in the original packaging materials. If they are not available, follow these directions:

a. Obtain a carton of corrugated cardboard having inside dimensions at least 6 in (150 mm) greater than the dimensions of the instrument.

b. Surround the product with a protective bag (anti-static preferred).

c. Pack dunnage or urethane foam between the product and the carton. If you use Styrofoam kernels, overfill the box and compress by closing the lid. There should be

3 inches (75 mm) of tightly packed cushioning on all sides of the instrument.

3. Seal the carton with shipping tape, an industrial stapler, or both.

DS1000 Series User Manual C–1

Appendix C: Service

Replacing the Fuse

1. Disconnect the power cable from the television demodulator rear panel.

2. Remove the fuse holder by inserting a suitable instrument on either side of the holder and pulling straight out.

3. Remove the old fuse and replace it with a new fuse of the same type. Use only 250 V, 1.6 A time-delayed fuses.

4. Replace the fuse holder ensuring that the holder clicks back into its socket.

Cleaning the Exterior

The instrument should be cleaned often enough to prevent dust and dirt from accumulating. Dirt acts as a thermal insulator, preventing effective heat dissipation and providing high-resistance electrical leakage paths between conductors or components in a humid environment.

CAUTION.

To avoid damaging the unit, do not allow water to get inside any enclosed assembly or component. Do not clean any plastic materials with benzene, toluene, xylene, acetone, or similar solvents, because they may damage the plastic.

Clean the dust from the outside of the instrument with a soft, dry cloth or small brush. A brush is especially useful for removing dust from around the buttons and connectors.

Bandwidth

The range of frequencies over which signal amplitude remains constant (within some limit) as it is passed through a system.

Baseband

The composite video signal before it modulates the picture carrier.

Composite video that is distributed throughout a studio and is used for recording is at baseband.

Broad Pulses

The vertical synchronizing pulses in the center of the vertical interval. These pulses are long enough to be distinguished from all others and are the part of the signal actually detected by vertical sync separators.

Burst

A small reference packet of the subcarrier sine wave sent on every line of video. Since the carrier is suppressed, this phase and frequency reference is required for synchronous demodulation of the color difference signals in the receiver.

B-Y

One of the color difference signals used in the NTSC and PAL systems. It is obtained by subtracting luminance (Y) from the blue camera signal (B).

Chrominance

The color information in a television picture.

Chrominance Signal

The high-frequency portion of the video signal, that is obtained by quadrature amplitude modulation of a 4.43 MHz (PAL) or

3.58 MHz (NTSC) subcarrier with R-Y and B-Y information.

Composite Video

A single video signal containing all of the necessary information to reproduce a color picture.

DS1000 Series User Manual Glossary–1

Glossary

CW

Continuous Wave. A separate subcarrier sine wave used for synchronization of chrominance information.

dB (Decibel)

A logarithmic unit used to describe signal ratios. For voltages, dB = 20 Log

10

(V

1

/V

2

).

Demodulator

In general, any device that recovers the original signal after it has modulated a high frequency carrier. In television, it refers to one of the following descriptions:

1. An instrument, such as the Tektronix DS1001, which takes video in its transmitted form (modulated onto the picture carrier) and converts it to baseband.

2. The circuits that recover R-Y and B-Y from the composite signal.

Field

Half of the video lines required to produce a full video frame. In interlaced scan systems, such as NTSC and PAL, the information for one video frame is divided into two fields. Two vertical scans overlay the two fields to produce the complete frame. In the complete frame, adjacent video lines in the picture are from alternate fields.

FM

Frequency Modulation. The process by which the frequency of a carrier signal is varied in proportion to the modulating signal, such as an audio signal. In the NTSC and PAL television systems, audio information is transmitted using FM.

Frame

Contains all the information required for a complete picture. For interlaced scan systems, there are two fields in a frame.

Harmonic Distortion

Signal distortion caused by non-linearities in a system. System non-linearities produce multiples of a single frequency signal applied to the the system. Harmonic distortion is evident when a pure sine wave applied to a system produces harmonic content at multiples of the sine wave frequency at the output.

Glossary–2 DS1000 Series User Manual

Glossary

Hum

The undesirable coupling of the 50 Hz (PAL) or 60 Hz (NTSC) power sine wave into other electrical circuits.

Intercarrier Sound

A method used to recover audio information. Sound is separated from video by beating the sound carrier against the video carrier, producing a 4.5 MHz (NTSC) or 5.5 MHz (PAL) IF that contains the sound information.

IRE

A unit equal to 1/140 of the peak-to-peak amplitude of the video signal, which is typically one volt. The 0 IRE point is at the blanking level, with the sync tip at –40 IRE and the white extending to +100 IRE. IRE stands for Institute of Radio

Engineers, the organization that defined the unit.

Linear Distortion

Distortions that are independent of signal amplitude.

Luminance

The signal (Y) that represents brightness, or the amount of light in the picture. This is the only signal required for black and white pictures. For color systems, it is obtained as a weighted sum

(Y = 0.3R + 0.59G + 0.11B) of the R, G, and B signals.

Modulated

When referring to television test signals, this term implies that chrominance information is present. (For example, a modulated ramp has subcarrier on each step.)

Modulation

A process that moves information around in the frequency domain in order to facilitate transmission or frequency-domain multiplexing.

Non-Linear Distortion

Signal distortion that does not increase at the same rate as the signal amplitude.

NTSC

National Television System Committee. The organization that developed the television standard currently in use in the United


Glossary

States, Canada, and Japan. Now, NTSC is generally used to refer to that standard.

PAL

Phase Alternate Line. One of the television systems used in Europe and many other parts of the world. The phase of one of the color difference signals alternates from line to line to help cancel out phase errors.

Quadrature AM

A process that allows two signals to modulate a single carrier frequency. Two signals amplitude modulate carrier signals with the same frequency but with a phase difference of 90 degrees (hence the term Quadrature). The two resultant signals are added together before transmission. Both signals are recovered at the receiver by demodulating them 90 degrees apart.

Quadrature Distortion

Distortion resulting from the asymmetry of sidebands used in vestigial sideband television transmission. Quadrature distortion appears when using envelope detection but can be eliminated by using a synchronous demodulator.

RF

Radio Frequency. In television applications, the television signal after the picture carrier modulation process.

RGB

Red, Green and Blue. The three primary colors used in color television’s additive color reproduction system. These are the three color components generated by the camera and used by the picture monitor to produce a picture.

Subcarrier

The high-frequency signal used for quadrature amplitude modulation of the color difference signals. The subcarrier frequency is 3,579,545 Hz (NTSC) or 4,433,618.75 Hz (PAL).

Synchronous Detection

A demodulation process in which the original signal is recovered by multiplying the modulated signal with the output of a synchronous oscillator locked to the carrier.


Glossary

Termination

An impedance at the end of a transmission line that matches the impedance of the source and of the line itself. Proper termination prevents amplitude errors and reflections. Video systems use 75

W transmission lines, so a 75

W

terminator must be at the end of any signal path. A receiving device connected to the transmission line may provide the necessary termination.

Vertical Interval

The synchronizing information that appears between fields and tells the picture monitor to go back to the top of the screen to begin another vertical scan.

Y

Abbreviation for luminance.

Zero Carrier Reference Pulse (ZCP)

A pulse in the vertical interval which is produced by the demodulator to provide a reference for evaluating the depth of modulation.
