1. INTRODUCTION

1.2.2 Maximum Allowable Input Voltage

Table 1-2 indicates the maximum signal voltage that can be applied to the input connectors. Do not apply excessive voltage to the connectors. Doing so may damage the instrument or lead to injury.

Table 1-2 Maximum allowable input voltage

Input Connector Maximum Allowable Input Voltage

FREQ STD 10MHz INPUT 3.3 Vp-p

1.2.3 Reverse Voltage and Excessive Input

Do not apply an external voltage to the output connectors. If the cable touches a DC power supply, the internal attenuators may burn out. Do not apply a signal that exceeds 3.3 Vp-p to the external input connector. If a DC component whose absolute voltage is 2 V or greater is superimposed on the signal, use capacitors to remove the DC component.

1.2.4 Backing Up the Panel Settings Memory

Because the LG 3810 has a last-memory feature, when you turn the power OFF, the last panel settings that were in use are retained. These panel settings are restored the next time that the LG 3810 is turned ON. If you are using the LG 3810 for the first time or if you do not use the instrument for 5 years or longer from the time that you purchase it, the retained panel settings may be lost.

Due to misuse, malfunction, or repairs, the contents of the LG 3810's memory may be changed or lost.

Be sure to make a backup of important information such as by recording the information on paper.

1.2.5 Mechanical Shock

This instrument contains sensitive components, so it may be damaged if it is dropped or otherwise exposed to a strong shock.

1.2.6 Networks

Controlling an LG 3810 remotely through the instrument's Ethernet interface has only been confirmed to work in a local network environment. LEADER does not guarantee that you will be able to control an LG 3810 remotely through the instrument's Ethernet interface in any network environment.

Back Up the Panel Settings Memory

1.2.7 Hard Disk Drive

The LG 3810 has a hard disk drive (HDD). The HDD is easily affected by factors such as vibration, mechanical shock, temperature, and humidity. The conditions of the operating environment may damage the data stored on the HDD or cause it to be lost. Pay attention to the following points when using the LG 3810.

• Do not apply vibration or mechanical shock to the LG 3810 when it is ON.

• Do not turn the power OFF when data is being written (data is being copied from the external USB device or over a LAN).

• Do not turn the LG 3810 OFF when you have remotely enabled its HDD write mode.

• Do not move the LG 3810 when it is ON or immediately after it has turned OFF.

• Do not turn the LG 3810 ON if condensation is present.

We have confirmed that stored data and the disk itself are not damaged if the LG 3810's power supply is interrupted during data playback. However, this may shorten the service life of the HDD, so we recommend that you stop playback before you turn OFF the LG

3810.

Depending on the environment and usage conditions, the HDD has a service life of a few years. When the HDD reaches the end of its service life, noise appears in decoded images and audio, and the LG 3810 may no longer playback data.

We recommend that you do not store important information in the LG 3810, but that you record a master version of the information to DVD or other media. If you will not use the LG 3810 for a long period of time, turn it OFF. Leaving it with the power ON may shorten the service life of the HDD.

2. SPECIFICATIONS

2.1 General

The LG 3810 is an RF signal generator that enables you to install optional encoders that support the standards for a variety of digital broadcast systems. The LG 3810 contains a TS generator, an encoder, a C/N generator, and an up converter. By changing the modulation method, you can easily transmit a modulation signal at a channel frequency in the VHF or UHF band. The LG 3810 also contains a pseudo-random (PN) signal source and a BER counter, so you can use this one instrument to perform BER measurements of receivers and tuners. In addition to using the internal TS signal source, you can also apply an external TS or playback a signal source from the internal HDD. This enables you to check images and audio that use an existing TS. By using the BER measurement feature, you can perform more comprehensive testing of receivers.

2.2 Features

• All-in-One

2. SPECIFICATIONS

Because the LG 3810 contains the features of both a signal generator and a BER measuring instrument in a single case, you can use it to check video in transport streams used in actual broadcasts as well as perform BER measurements on front-end devices. The LG 3810 can also be used as a comprehensive signal generator for STB or tuner production lines.

• Enables You to Specify the Digital Broadcast System

You can install optional encoders that support the standards of the digital broadcast systems that you want to generate signals for. You can also insert additional options after the LG 3810 has been installed. You can easily specify the modulation method from the front panel, which uses a QVGA LCD to display the LG 3810's settings graphically.

• Real-time MPEG-2 TS Encoding and Modulation

The LG 3810 can encode and modulate, in real time, a transport stream that is applied to the DVB-ASI or SPI connector or that is saved to the HDD.

• Enables You to Playback a Transport Stream That Runs for a Long Time from the HDD

Because the LG 3810 has an 80 GB HDD, you can playback data that requires a large amount of storage memory, such as streams that contain HDTV contents and transport streams that run for a long time.

• Enables You to Connect External HDDs or DVD Drives

You can connect an external HDD or DVD drive to the one of the LG 3810's USB 2.0 ports and playback a TS directly from the HDD or DVD-ROM. You can copy TS data that has been recorded to a DVD-ROM or CD-ROM to the internal HDD. This enables you to use a variety of existing transport streams to check video and audio.

• 100 Presets

You can store up to 100 presets in the LG 3810's internal memory. You can separate presets into up to 10 groups. This enables you to use presets for different purposes depending on the inspection that you want to perform.

About mounting external USB devices

• If you connect external USB devices to the LG 3810, and then turn its power ON, the LG 3810 starts with the connected devices already mounted.

• If you mount an external USB DVD-ROM drive with a disk already inserted, the DVD-ROM drive's eject button will be disabled. To change the disk, unmount the drive.

• You cannot mount external USB devices while you are playing back a TS file that is stored on the internal HDD or an external USB device. To mount other external USB devices, stop playing back the TS file.

• If the external USB device that contains the TS file that is being played back is removed from the LG 3810, the TS file playback stops. To reconnect the external USB device to the LG 3810, first unmount the disconnected device, and then mount it again.

6.1.3 Removing an External USB Device

Figure 6-9 TS playback

If, as a result of the analysis, the LG 3810 determines that this file is not supported, F1 Play Mode and F4 Play disappear.

Figure 6-10 When a file cannot be played back

Notes regarding TS playback

There are the following conditions regarding what TS files can be played back on the LG

3810.

• The TS files that can be used must be either MPEG-2 TS format files that conform to ISO/IEC13818-1 or broadcast TS format files that are defined by ARIB STD-B31.

• Packet sizes of 188 or 204 bytes are supported. For broadcast TS files, only packet sizes of 204 bytes are supported.

• At least one type of PCR whose bit rate can be analyzed must be embedded in the file, and the bit rate that is calculated from the PCRs must be within the range of 0.2 to 40 Mbps. If no PCR is embedded in the TS, or if the calculated bit rate is outside of the specified range, the TS cannot be played back.

• If the playback time that is calculated from the analyzed bit rate and the file size is less than 5 seconds, the TS cannot be played back.

Page 37

6. DETAILED SETTINGS

Additionally, even if the LG 3810 recognizes the TS as one that can be played back, if the TS does not meet the following conditions, it may not provide correct signal generation.

• The TS has a fixed rate. Transport streams whose bit rates change dynamically or transport streams that consist of a series of transport streams that have different bit rates are played back with the bit rate that is initially detected.

• The TS may not be played back correctly depending on the state of its internal embedding. Additionally, for transport streams that have packets that are not the correct length in the middle of the packet stream, the signal is interrupted because the encoder must re-synchronize.

• Up to eight PCRs can be updated. If PCR Update is ON, PCR values after the broadcast TS conversion are corrected. During loop playback or if the PCR values are reversed, the initial values are retrieved and corrected again.

• Counting down of the modulation parameter (TMCC) is not supported for broadcast transport streams. When the parameter is changed, because the encoder resets, the modulated wave is interrupted. When playing back files that have a low bit rate of 1 Mbps or less, pay attention to the following:

- There is a time lag of a few seconds to a few tens of seconds between when you press the play button and when TS playback actually begins.

- The LG 3810 handles data in units of approximately 520 KB. If a file is smaller than 520 KB, the LG 3810 automatically specifies a number of times for the file to loop so that it exceeds 520 KB. Therefore, even if you play back the file in Once mode, it will loop more than once.

- There may be a delay between when Play or Stop is displayed on the screen and when the output actually begins or stops.

• Seamless playback is not supported. PTS/DTS and continuous counter updating are not carried out.

• Only use devices that support USB 2.0 when you are playing back a TS from an external USB device.

• If the external USB device that contains the TS file that is being played back is removed from the LG 3810, playback continues if the LG 3810 is performing RAM playback. If the LG 3810 is not performing RAM playback, it plays the file up to the point that the external USB device was removed and then stops playback (even if Loop playback is turned ON).

• You can play back a TS directly from an external USB DVD-ROM drive, but because factors such as the bit rate of the TS being played back are affected by the type of disk used and the state of the recording, direct playback from a DVD-ROM drive is not guaranteed.

• When you play back a TS from an external USB HDD, depending on the state of the recording of the TS data, noise may appear during playback of the video or audio. If this symptom appears, connect the external USB device to a PC and defragment the USB device, and then play back the file again.

• You cannot use the LG 3810 to perform VFAT or NTFS format defragmentation of external USB HDDs.

6. DETAILED SETTINGS

• F3 RAM

Specify whether or not to perform RAM playback of the selected TS. This is set to Off by default.

Off Data is modulated at the same time that it is transferred to the internal RAM.

There is almost no delay between when playback is started and the modulated wave is generated (factory default).

On If the data that is being played back or the file size specified by F4 Range is

419 MB or less, data is transferred to the internal RAM, and played back from there. There is a delay between when playback is started and the modulated wave is generated. If the size of the playback data exceeds 419 MB, the LG 3810 performs the same as if F3 RAM were set to Off. If you want to play back a TS file for a long time, we recommend that you use data whose size makes RAM playback possible.

• F4 Range

Specify whether or not the selected TS will be played back over a specified range. This is normally set to Disable (playback the entire file from its beginning to end). [ Enable / Disable

Page 42

6. DETAILED SETTINGS

About the TS playback range

• The displayed time is calculated from the detected bit rate and the file size. Depending on the data, there may be a small degree of error in this calculation.

• When you specify the range in terms of time, the range in terms of packets is automatically calculated. The minimum time unit that you can use to specify the time is

0.1 seconds.

• If an incomplete data byte exists at the start or end of the data, the LG 3810 ignores this data fraction and plays data back in units of packets.

• For broadcast transport streams, the number of packets that are played back is an integral multiple of the number of ISDB-T frame packets.

• When you specify a playback range, if the specified number of packets is not a multiple of the number of frame packets, the LG 3810 automatically rounds down the number of packets to play back a number of packets that is a multiple of the number of frame packets.

• You cannot specify a time that is less than 5 seconds.

• You cannot specify a playback range of 1000 hours or more.

6.1.9 Performing File Operations over a LAN

The LG 3810 has a file server to enable you to control its internal HDD. You can use this feature to perform file operations on the LG 3810's internal HDD over a LAN from your PC.

To control the LG 3810, we recommend that you use a PC that conforms to the following guidelines. OS Microsoft Windows 2000 (SP4) or XP (SP3) CPU Intel Pentium or Celeron or a compatible CPU LAN 10BASE-T/100BASE-TX port Application MS-DOS, DOS window, or command prompt

Follow the procedure below to configure your PC and connect it to the LG 3810. The following settings are used as an example in this procedure. IP address 192.168.0.1 Subnet mask 255.255.255.0 Default gateway 192.168.0.1 LG 3810 server name LG3810 Workgroup name WORKGROUP

1. Configure the TCP/IP settings

Match the LG 3810's TCP/IP settings to the network that you want to connect it to. For details on your network settings, such as TCP/IP, server name, and workgroup, consult your network administrator.

To display the TCP/IP screen, on the UTILITY screen, press F1 Config to display the CONFIG screen, and then press F1 TCP/IP. Specify the IP address, subnet mask, and default gateway, and then press UP MENU.

Figure 6-18 TCP/IP screen

2. Connect the LAN cable

Use a LAN cable to connect the rear panel Ethernet port to your PC. If you are connecting the LG 3810 to your PC in a one-to-one manner, use a crossover cable. If you are using a hub to connect the LG 3810 to your local network, use a straight cable.

Page 45

6. DETAILED SETTINGS

3. Connect to telnet

On your PC, open a DOS window or a command prompt, and then enter the following commands.

C:\>telnet 192.168.0.1 <Enter> LG3810 login : lg3810 <Enter> Password : lg3810 <Enter>

After you have logged on to the LG 3810, the message “lg3810@LG3810:~$” appears.

4. Set the file server name

The first time that you access the file server, use the “NAM” code to set the file server name. For example, if you want to set LG3810 as the file server name:

$ rem NAM LG3810 <Enter>

5. Set the workgroup name

The first time that you access the file server, use the “WGP” code to set the workgroup name. For example, if you want to set WORKGROUP as the workgroup name:

$ rem WGP WORKGROUP <Enter>

6. Enable the file server

Send the following command to enable the LG 3810's file server.

$ rem FSV ENABLE <Enter>

7. Enable the HDD write mode

If you want to write data to the internal HDD, use the “HDW” code to enable the HDD write mode.

$ rem HDW ENABLE <Enter>

Important notes regarding the HDD write mode

• Specify the file server name and the workgroup name when the file server is disabled.

• When you have finished writing data to the HDD, be sure to send the “HDW” code to disable the HDD write mode (see step 9). If you leave the HDD write mode enabled and turn the LG 3810 OFF, the next time it turns ON, the LG 3810 will perform a file system recovery, which takes several minutes to complete.

• When you enable the HDD write mode, to concentrate the internal processor power on writing data to the internal HDD, stop performing standard operations on the LG 3810. While the HDD write mode is enabled, the following operations are not guaranteed.

Updating of the LCD panel (alarms, BER measured value, GO/NO GO, etc.) RF signal generation when a TS is being played back from the HDD or an external

DVD drive

• When a file is being written to the HDD, all operations are not guaranteed.

Page 46

6. DETAILED SETTINGS

• When you want to write a file to the HDD, be sure to stop playback, and then enable HDD write mode.

• When a file is being written to the HDD, do not perform panel operations.

Figure 6-19 Remote control from a DOS window

8. Search for the file server on your PC

Start Explorer on your PC, and then type the file server name (\\Lg3810\hdd) in the address bar to search for it.

When the PC finds the file server, the contents of the LG 3810's internal HDD are displayed in Explorer. By dragging or copying and pasting files, you can perform operations such as writing data to the internal HDD, copying data to your PC, and changing file names. (When the LG 3810 is connected to a PC in a one-to-one manner, the data rate is approximately 70 Mbps.)

Notes regarding file operations

• File names can consist of the following characters. Alphanumeric characters A to Z, a to z, and 0 to 9 Symbols # $ % + , . = [ ] ^ _ { } ~ -

• Do not use the following characters. File names that contain these characters cannot be displayed. Characters ! & ' ( ) * / : ; < > ? \ | (the space character)

• Files whose full paths exceed 240 characters in length cannot be loaded or played back. Keep this character length in mind when you design the folder hierarchy.

• Each folder can store a maximum of 64 files. To copy more than 64 files, add new folders over then LAN, and then split the files that you want to copy into these folders.

• To ensure that a file name fits on the LCD, file names, including the file name extension, should be a maximum of 20 characters.

• The LG 3810 does not prevent you from copying files whose size exceeds the remaining free space on the internal HDD when you perform file operations over a LAN. If you copy a file whose size exceeds the remaining free space, the size of the file that is actually copied to the HDD and the file size that is shown on the file's properties will not match.

Page 47

6. DETAILED SETTINGS

• If you cancel a copy operation while the file is being copied, the data that was copied up to that point remains on the internal HDD. Use Explorer or another file manager to delete the partial file.

• If you write a file to the internal HDD whose file name already exists, the existing file is overwritten.

• If you reorder files on the PC, the new order is not reflected on the LG 3810.

9. Finish writing to the HDD

When you are finished writing data to the HDD, be sure to use the HDW command to disable the HDD write mode.

$ rem HDW DISABLE <Enter>

● Changes to network parameters

When you change network parameters (including changing settings remotely), the timing for when the changes take effect is shown below.

• When you switch the reference signal, because the hardware is reset, the signal stops for a fixed period.

• All the LG 3810 clock signals are generated from this reference signal, so the purity (phase noise characteristic) and deviation of the reference signal directly affect the encoded or modulated signal.

• ARIB STD-B29 and B31 specify the permissible IFFT sample frequency deviation to be ±0.3 ppm. Subsequently, depending on the characteristics of the reference signal, the tuner may not be able to receive it. When applying an external reference signal, apply signals that are pure, stable, and precise. The F STD alarm on the top screen is cleared when a comparatively wide range (approximately 50 ppm) of signals is applied, but the LG 3810 simply monitors the 10 MHz PLL circuit lock signal for this purpose. This does not guarantee the performance of the RF signal generation.

8. GPIB

The LG 3810 is standard-equipped with a GPIB (IEEE 488) external control connector. You can use GPIB to configure the LG 3810's main settings.

Note

• The LG 3810 GPIB operation has been confirmed using a GPIB board (PCI-GPIB and PCMCIA-GPIB) manufactured by National Instruments Corporation. If you use products that are not manufactured by National Instruments Corporation to control the LG 3810, the operation of such devices may differ from what is explained in this manual. As such, we recommend that you use products that are manufactured by National Instruments to control the LG 3810.

8.5 Clear and Reset

You can reset or clear the LG 3810 by transmitting a command to it or by performing a special operation. The responses to the various clear and reset commands are shown below.

● IFC (Interface clear)

In response to receiving the universal command IFC, the LG 3810:

• Clears the state of the specified talkers and listeners.

• Leaves the GPIB buffer and commands that are on standby as they are.

• Leaves the remote status setting as it is.

• Leaves the panel settings as they are.

● DCL, SDC (Device clear)

In response to receiving the universal command DCL or the address command SDC, the LG 3810:

• Clears the GPIB buffer and commands that are on standby.

• Leaves the interface (the state of the specified talkers and listeners) as it is.

• Switches to remote mode.

• Leaves the panel settings as they are.

● Restarting the LG 3810

8. GPIB

When the LG 3810 is restarted, it:

• Clears the state of the specified talkers and listeners.

• Clears the GPIB buffer and commands that are on standby.

• Switches to local mode.

• Displays the top screen when it starts, regardless of the screen that was displayed before it was turned OFF.

8.6 Remote/Local

You can use the system controller or the front panel REMOTE key to switch the LG 3810 between remote and local mode. The LG 3810 is always in either local or remote mode. These modes are explained below.

● Local mode

The LG 3810 switches to local mode when:

• Its power is turned ON (immediately after it starts).

• The REMOTE key is pressed and the key's LED turns OFF.

• A GTL command is received.

• It is in remote mode and the remote mode is cleared.

● Remote mode

If REN is true and the LG 3810 is specified as a listener, it switches to remote mode. When the LG 3810 switches to remote mode, the REMOTE key LED lights. When the LG 3810 is in remote mode, all panel keys except for the power switch and the REMOTE key are locked. In this mode, control of the LG 3810 over Ethernet is enabled. Control through the remote connecter is also enabled. Only connect the ETHERNET port or REMOTE connector to a PC or control device if you will use these non-GPIB interfaces to control the LG 3810.

Page 75

8.7 Multi-Line Message Commands

This section will explain the types of multi-line message commands that the LG 3810 supports and whether or not a response is returned for each command.

8.8 Program Message Format

8. GPIB

To use the GPIB interface to configure the LG 3810, you have to send program messages to the LG 3810 from a controller. Program messages are constructed from a single program code or multiple program codes. In a single program message, the LG 3810 can receive up to 255 bytes (including delimiters) of program codes written in ASCII characters. When there are multiple program codes, any program codes that contain unspecified headers or parameters that are outside of the valid range will be ignored, but all other program codes will be executed.

8.9 Program Message Terminators

This section will list the delimiters that can be used to separate program messages. The LG 3810 supports the terminators that are shown below. The instrument ignores the CR character.

• LF

• LF+EOI

• EOI

Response message separator “;” (ASCII code 3Bh) Response message terminator “CR+LF+EOI”

Page 76

8.10 Program Code Format

8. GPIB

Program codes are constructed from headers and the necessary number of data blocks.

● Characters

Use capital letters for the headers and data.

● Separator between headers and data

Insert a space (ASCII code 20h) between the headers and the data. For queries, insert a space before the “?.”

● Program message unit separator

Use the semicolon (ASCII code 3Bh), to separate multiple messages when you transmit them all at the same time.

● Program data separator

Use the comma (ASCII code 2Ch), to separate multiple parameters.

9. ETHERNET

You can use the LG 3810's Ethernet port to configure its main settings remotely.

9.1 Connection Procedure

To connect the LG 3810 to an Ethernet, connect a 100BASE-TX STP cable to the LG 3810's Ethernet (ETHER) port. If you are connecting the LG 3810 to your PC in a one-to-one manner, use a crossover cable. If you are using a hub to connect the LG 3810 to your local network, use a straight cable. Consult your network administrator, and configure the LG 3810 TCP/IP settings to match your local network environment.

You can control the LG 3810 over an Ethernet at the same time that the instrument is being controlled (remotely) through GPIB. If you want to only control the LG 3810 over an Ethernet, disconnect all other control cables from the instrument.

9.2 Operations on Your PC

9. ETHERNET

Use TELNET*1 to control the LG 3810 remotely from a PC that is connected to your network. For information on how to start TELNET, see your PC's instruction manual. All LG 3810 operations have been confirmed to work on Windows 2000 (SP4) and Windows XP (SP3). However, depending on compatibility with your PC's environment, some operations may not work.

When you start TELNET, “login:” is displayed. Enter “lg3810.” Next, “Password:” is displayed. Enter “lg3810.” (You cannot change the login name and password on the LG 3810.)

To execute commands, type “rem” followed by the program codes that were listed in Table 8-4 and Table 8-5. Additionally, you can query settings by appending “?” to commands.

● Example 1

To set the frequency to 500 MHz and the output level to -60 dBm, send the following commands. “_” represents a space character. Insert a space between the header and data codes. rem_RF_500 Enter rem_LM_-60 Enter

● Example 2

To read the channel setting, send the following command. “_” represents a space character. Insert a space between the header and data codes and before the “?” character. rem_CH_? Enter

*1 Example of starting TELNET on Windows XP (the IP address assigned to the LG 3810 is 192.168.0.1)

1. On the taskbar, click Start, and then click Run.

2. Enter “TELNET 192.168.0.1.”
