SAFETY PRECAUTIONS
There is always a danger present when using electronic equipment.
Unexpected high voltages can be present at unusual locations in defective equipment
and signal distribution systems. Become familiar with the equipment that you are
working with and observe the following safety precautions.
Every precaution has been taken in the design of your Satellite Modulator to
insure that it is as safe as possible. However, safe operation depends on you the
operator.
Always be sure your equipment is in good working order. Ensure that all points
of connection are secure to the chassis, and that protective covers are in place
and secured with fasteners.
Never work alone when working in hazardous conditions. Always have another
person close by in case of an accident.
Always refer to the manual for safe operation. If you have a question about the
application or operation call Sencore for assistance.
WARNING – To reduce the risk of fire or electrical shock never allow your
equipment to be exposed to water, rain or high moisture environments. If
exposed to a liquid, remove power safely (at the breaker) and send your
equipment to be serviced by a qualified technician.
To reduce the risk of shock the SMD 989 must be connected to a mains socket
outlet with a protective earthing connection.
For the SMD 989 the mains plug is the main disconnect and should remain
readily accessible and operable at all times.

SMD 989– User Manual
Introduction
The SMD-989 is a versatile DVB-S/S2/S2X/TurboPSK modulator platform capable of one or two
channels of modulation per rack unit. The SMD-989 comes standard with IP and ASI inputs to
offer flexibility for future changes in network architecture or sourcing content from two different
interfaces. The SMD also supports advanced DVB-S2 features such as 16APSK and 32APSK
modulation as well as the carriage of multiple streams on a single RF carrier. It further supports
the advanced modulator coding scheme turbo PSK and S2X.
This manual describes how to install, configure, and operate the SMD 989 DVBS/S2/S2X/TurboPSK Modulator. It is written for professional operators of video distribution
systems and assumes a prerequisite level of technical knowledge.
The SMD 989 is controllable through the front panel interface, a supported web browser and/or
via SNMP which also provide alarms and traps that may be configured to alert users when errors
occur through automation systems.
Through the SMD 989 web interface, front panel, or SNMP the user can perform tasks such as
configuration, monitoring, and troubleshooting.

Hardware Overview
The SMD 989 consists of a chassis with two bays which can house individually configured
modulators. There are two different modulator options including the SMD 910 or SMD912(A).
These options are described in the next section of this manual. Each modulator option can be
configured to support either IF or L-band outputs. The modulators support all DVB-S/S2
modulation types from QPSK to 64 APSK. The SMD 910 modulator can be upgraded to support
multistream outputs with streams input to one of the four ASI ports or IP interface. The SMD912
modulator can be upgraded to support Turbo PSK advanced modulation. This section of the
manual describes the chassis and hardware options available.
SMD 989 Chassis and Controller
The Sencore SMD 989 satellite modulator platform can be configured in multiple hardware
configurations. The two bays with the controller located in the middle of the chassis as shown in
Figure 1.
The controller module hosts the graphical user interface along with the relays and 10 MHz input
reference. Looking at the rear of the chassis, the left slot is bay 1 and the right slot is bay 2.
Each bay is independently controlled and operated. Therefore each bay needs to be configured
separately in order to ensure the expected operation.
The SMD 989 platform offers eight modulation options. The modulation module is the SMD 910
which includes an MPEGoIP input via RJ45, four ASI inputs via BNC connectors, and an IF
output via a BNC connector. The SMD 910 option can be configured with an optional L-band
output module, the SMD 920 which includes and L-band output via an SMA connector. The other
licenses available are software licenses enabling features for bitrates, DVB-S2, and multistream.
Alarm Contact Closure
The Alarm contact closure output connector allows a user to configure two separate contacts that
can be used to drive external alarm indicators (sirens, flashlight etc.) or can be used to connect to
a redundancy switching system. The pinout in Figure 3 shows the relays in a de-energized state.
When the SMD 989 is on the relays energize. This allows the possibility to monitor the state of
the relays if the unit losses power the relays de-energize and a redundant unit can be activated.

10 MHz Reference Input
The clock input (CLK IN) is used when a reference with enhanced stability is needed or when
several modulators need to be synchronized to the same clock source. The level should be 0
dBm nominally or within a range of -3 to +7 dbm.. The unit automatically senses and switches
between the internal or external reference based on presence detection. By default, the internal
clock reference is used. When an external clock input is sensed, the unit automatically locks to
the incoming reference.
10 MHz Reference Output
The clock output (CLK Out), not shown in figure 1, is used to provide a sample of the internal
reference clock when it is desired to synchronize other equipment to the modulator’s reference
clock or output. The output level is approximately 0 dbm. This output is subsequently and
automatically locked to a 10 MHz reference input when an input is applied to the 10 MHz
Reference Input.
Control Ethernet Connection
A standard RJ-45 connector provides connection to the SNMP and Web Interface of the SMD
989 platform. The connection is a 10/100 BaseT connection. A user can view the IP address of
the unit from the front panel or once known can access the web interface through any supported
web browser by typing the IP address of the unit. The control port is capable of both DHCP and
static IP addressing. By default the IP address of the SMD 989 is statically set to 10.0.0.60.

set to Include any streams originating from
the user defined IP addresses will be
received.
With the SMD 912(A) the input buffer size is settable at a range from 1 to 4,000 KB. The larger
the buffer size, the more latency will be created in the system. The tradeoff is a potential for IP
jitter and dropped packets. It further permits setting an input buffer delay of 1 to 4000 mS.
The advanced settings allow source specific multicasting using IGMP v3 joins. The filter can be
set to exclude or include. IGMP addresses can be added and removed by clicking the

Configure Modulator – Inputs
The Input tab provides selection of the Primary Input and the option to enable a Backup Input to
the modulator. A backup input may be selected in the event of a primary input fault. The selected
Primary or the Backup Input is routed to the main modulator input. The selected Primary and
Backup Inputs must be enabled and active inputs. (See the previous section of this manual)
Switching Manually from Primary Input To Backup Input:
You can switch manually between the Primary Input and Backup input with the icon located at the
top of the middle modulator section. Click on the icon. This icon changes
to a Switch to Primary Input icon when the Backup Input is active.
There are several options for defining failover conditions in which the input to the modulator
switches from the Primary Input to the Backup input. There are also options for defining
conditions in which the input returns from the Backup Input to the Primary Input.
- Failover to Backup can be set to On Primary TS Sync Loss, On Primary TS
Analysis Failure or Manual Only. TS Sync Loss mode allows the SMD 989 to switch
to backup if the primary input transport sync is lost. In TS Analysis mode failover is
based on transport stream errors or sync loss. This allows the SMD 989 to switch to
a backup source when there are errors in the transport stream even if it does not lose
sync. (TS Analysis Failover/Restore switching requires SMD 970 TS Analysis Option)
If TS Sync Loss Failover is selected. Restore to Primary can be set to Manual Only,
On Primary TS Sync Restored, or On Backup TS Sync Loss. The switchover
Interval(s) can be set from 1 to 20 seconds.
If TS Analysis Failover (option) is selected, Restore to Primary options are Manual
Only on Primary TS Analysis Restored or On Backup TS Analysis Failure. Failover
conditions can be enabled/disabled and Switch After interval can be set from 1 to 30
seconds.
IMPORTANT NOTE: When selecting TS Analysis Failover for Primary or Backup inputs, the
TS Analysis feature must be enabled or active for the respective primary and/or backup.

Configure Modulator – Modulation Parameters
The Modulation tab provides setup settings of the modulation parameters. First, choose the
Modulation/FEC code to use and then select how you wish to set the output symbol rate. You
may enter the desired output symbol rate or input bit rate or have the internal calculator
recommend a setting. The following section describes entry of these parameters.
The Enter Rate By field provides the user a choice of how to setup the output Symbol Rate or
Max Bitrate entry fields. The values in these fields are mathematically related depending on the
modulation mode, modulation type, and FEC settings. The SDM 989 contains an internal symbol
rate or max. input bitrate calculator to assist.
Enter Rate By
- Output Symbol Rate
- Input Bitrate
Description: Output Symbol Rate mode allows the entry of the desired output symbol rate. The
SMD 989 calculates the maximum input bit rate and lists it in the Max. Bitrate field.
Description: Input Bit Rate mode allows the entry of a known input bit rate. The SMD 989 then
calculates the needed symbol rate and lists it in the Symbol Rate field.
With output Symbol Rate you enter the desired output symbol rate. It must be mathematically
proper based upon the input bit rate measured by the system. When a higher than needed
symbol rate is entered, the modulator inserts null packets to achieve the rate. When entering a
lower than needed symbol rate the SMD 989 removes nulls, if they exist, from the stream.
With Input Bitrate, the SMD 989 uses the entered bitrate along with the modulation settings to
calculate the needed symbol rate. If it is known that the input transport stream contains a
significant amount of null packets it is possible to enter a bitrate that is lower than the actual input
transport stream bitrate. In this case the SMD 989 will remove existing nulls.
Important Note: When entering a bitrate lower than the input bitrate or a symbol rate below
the minimum, there must be enough nulls in the input transport stream to be removed to
allow the lower bitrate or symbol rate or errors in the transmission transport stream result.
The SMD 989 contains a symbol rate or input bit rate calculator to assist with these selections. By
clicking the icon, the recommended symbol rate will be inserted into the Symbol Rate field
or maximum input bitrate inserted in the Bitrate field.

The remaining settings include (Bold indicates default):
Pilot Insertion (Only available in DVB-S2 Modes)
- Enable
- Disable
Description: When enabled, every 16 slots of 90 symbols the modulator will insert 36
non-modulated symbols to aid in receiver synchronization. The use of a pilot allows the
receiver to maintain carrier recovery, even when the user data payload cannot be
decoded.
Frame Size (Only available in DVB-S2 Modes)
- Normal (64,800 bits)
- Short (16,200 bits)
Description: Short frames introduce more overhead but give a shorter encapsulation
delay. Short frames are 4 time shorter than normal frames.
Spectral Inversion
Page 37 (105)
- Normal
- Inverted
Page 38
SMD 989– User Manual
Description: Determines whether the spectrum is inverted or normal.
Note: When the SMD 920 L-Band option is installed, the default spectral inversion is
inverted as the upconverter will invert. Setting the output to Inverted will give a normal
output from the upconverter. This is shown in the RF Output status for Spectral Inversion.
Alpha Filter Rolloff
- 0.35
- 0.25
- 0.20
- 0.15
- 0.10
- 0.05
Description: The filter rolloff is known as the Alpha coefficient (α). The smaller the α, the
less bandwidth will be required on the satellite.
Rate Adaptation (Only available in DVB-S2 single mode)
- Disable
- Enable
Description: When set to enable a rate adaption is applied to the DVB-S2.mode. When
disabled the rate adaptation is not active. Rate adaptation forces the modulator to add or
remove null packets and re-stamp PCRs in order to match TS bitrate to the modulation
payload rate. Disabling rate adaptation is desirable where the input TS must be
preserved through the transmission chain. In such use cases, it is expected that the input
TS bitrate is fairly consistent and the payload mismatch can be resolved by occasionally
inserting a dummy frame instead.
PL Scramble Code (Physical Layer Scrambling is only available in DVB-S2 or DVB-S2X
single modes)
Description: This is used to specify a randomized scrambling sequence applied to each
PL frame and initiated at the end of each PL header. Scrambling randomizes band
energy dispersion and allows for a “signature” when may provide association to a satellite
operator or satellite. The complex code relates to an “n” value defined by an entry of 0 to
262 141.
PRBS Enable/Disable A pseudo random binary sequence test signal is available for
testing. When Enabled the PRBS replaces the normal input modulation feeding the
modulator. Select Disabled for normal output applications. See the PRBS section of this
manual for added information.

Configure Modulator – S2 Multistream
Configuration for DVB-S2 Multistream Modulation is similar to single stream settings with the
ability to add 6 streams to the modulation as shown in Figure 35 below.
Figure 35 SMD 963 multi-stream configuration
Multi-stream is supported in DVB-S2 CCM and VCM modes using the SMD910 modulator. Multistream DVB-S2 CCM limits the modulation type and FEC to the same for all the streams. Multistream DVB-S2 VCM as shown in Figure 35 allows a modulation type and FEC to be set for each
stream in the modulation.
Each input can be set to the desired incoming stream. If the input set to “OFF” the stream is not
configured to be used in the modulation. If the Input is set to something other than OFF and no
stream is present, an error indicating that input is missing is generated.
For each stream an Input Stream Identifier (ISI) is needed. This value is used by receivers to
select the appropriate stream out of the multi-stream modulation.
Note: When in the Multi-stream Modulation mode, the input backup and TS Analysis features are
not available.

The Modulation tab provides setup settings of the modulation parameters. First, choose the
Modulation/FEC code to use and then enter the desired output symbol rate or input bit rate. The
following section describe the Turbo PSK parameters.
The Enter Rate By field provides the user a choice of how to setup the output Symbol Rate entry
fields. The values in these fields are mathematically related. The SDM 989 contains an internal
symbol rate calculator to assist.
Enter Rate By
- Output Symbol Rate
- Input Bitrate
Description: Output Symbol Rate mode allows the entry of the actual output symbol rate desired.
With Input Bitrate by entering the bitrate of the input transport stream the SMD 989 uses this
bitrate along with the Modulation/FEC settings to calculate the modulation symbol rate. If it is
known that the input transport stream contains a significant amount of null packets it is possible to
enter a bitrate that is lower than the actual input transport stream bitrate. In this case the SMD
989 will remove the nulls.
Note: When entering a bitrate lower than the input bitrate there must be enough nulls in the input
transport stream to be removed to allow the lower bitrate. Entering a bitrate that is too low will
result in transport stream errors.

selected for use. The Advanced section provides settings for Sync Byte Deletion, Reduced
Latency, and PRBS.
Page 46 (105)
Page 47
SMD 989– User Manual
Figure 40: Reduced Latency Selections
Sync Byte Deletion: The Sync Byte Deletion advanced feature permits removal of the incoming
MPEG stream sync bytes from reaching the modulator. so as to not output symbols containing
the sync byte information. This enables a savings in bandwidth of 1 byte every 188 bytes as
modulator output symbols containing sync byte data are removed.
The Sync Byte Deletion setting can be disabled or enabled. When set to Enabled, the modulator
blocks the incoming Sync Byte. When Enabled the receive demodulator must reinsert it. When
Disabled the modulator receives the full transport stream including the Sync Bytes.
Reduced Latency:
The advanced section contains several reduced latency modes which may be applied to the
TurboPSK modulation. The reduced latency modes of the TurboPSK modulation provides several
levels of latency that can be applied. The reduced latency modes are only applicable to special
low symbol rate data satellite applications using the TurboPSK modulation.
Reduced Latency Selections
- Disabled: (Default) No latency reduction - with additional input buffering
- Normal: Introduces slight latency without additional input buffering
- Reduced 1: Adds latency reduction to the Normal mode
- Reduced 2: Adds latency reduction to the Reduced 1 mode
- Reduced 3: Adds latency reduction to the Reduced 2 mode
- Minimum: Adds latency reduction to the Reduced 3 mode
PRBS (Pseudo Random Binary Sequence): The PRBS feature provides a digital test
signal with known properties used for BERT (bit error rate testing) of satellite equipment
or transmission paths. Test signals used are a binary PN (Pseudo-Noise) signal known
as a PN-23 or Inverted PN-23. The test signal is selected within the PRBS tab/menu.
For BERT tests, the PRBS setting may be set to Enabled. When Enabled, the normal
input signal to the modulator is removed and replaced with the PN-23 or Inv PN-23
signal.
IMPORTANT: For normal or non-testing applications in which the input is to be
used to modulate the satellite IF or L-Band carrier output, the PRBS test signal
must be set to DISABLED.

Description: When set to enable a rate adaption is applied to the DVB-S2X.mode. When
disabled the rate adaptation is not active. Rate adaptation forces the modulator to add or
remove null packets and re-stamp PCRs in order to match TS bitrate to the modulation
payload rate. Disabling rate adaptation is desirable where the input TS must be
preserved through the transmission chain. In such use cases, it is expected that the input
TS bitrate is fairly consistent and the payload mismatch can be resolved by occasionally
inserting a dummy frame instead.
PL Scramble Code (Physical Layer Scrambling is available in DVB-S2X single mode)
Description: This is used to specify a randomized scrambling sequence applied to each
PL frame and initiated at the end of each PL header. Scrambling randomizes band
energy dispersion and allows for a “signature” when may provide association to a satellite
operator or satellite. The complex code relates to an “n” value defined by an entry of 0 to
262 141.
PRBS Enable/Disable A pseudo random binary sequence test signal is available for
testing. When Enabled the PRBS replaces the normal input modulation feeding the
modulator. Select Disabled for normal output applications.
The PRBS feature provides a digital test signal with known properties used for BERT (bit
error rate testing) of satellite equipment or transmission paths. Test signals used are a
binary PN (Pseudo-Noise) signal known as a PN-23 or Inverted PN-23. The test signal is
selected in the PRBS tab.
IMPORTANT: For normal or non-testing applications in which the input is to be
used to modulate the satellite IF or L-Band carrier output, the PRBS test signal
must be set to DISABLED.

Figure 43: Outputs section
Output Settings
This section focuses around the IF and optional RF (SMD 920 option) settings found on the right
column of the individual bay home screen.
All SMD 989 modulations will have an IF output area indicating an active or muted output,
frequency range from 57 up to 145 MHz, output level and tilt level. If the SMD 920 L-Band option
is available it will indicate the RF settings for the module as shown in Figure 43.
There are three quick access buttons at the top of the Outputs section. These buttons provide
easy access to common functions or functions that may need to be accessed quickly.
- Mute: By clicking the mute button the IF/RF outputs will be muted. When the output is
muted the icon will change to “Unmute”
- Modulating: Clicking the Modulating quick access icon will stop modulated output and
go to a carrier wave (CW). When in CW mode the Modulating icon will change to a
CW image and read “CW Only”
- RF Level (dBm): This allows the RF output level to be adjusted by either entering the
value, from -30dBm to 5dBm, or by using the up and down arrows.

Figure 44: IF settings
IF Output
Clicking on “Configure IF Options” will produce a dialog box as shown in Figure 44.
The output can be set as active or mute.
The IF output frequency is selectable between 57 & 140 MHz in 1 Hz increments. When used
with the option SMD 920 RF Upconverter set the IF frequency to 70MHz or 140MHz and the level
to -10dBm.
The level for the IF Output is adjustable between -30 to -5 dBm for the SMD 910 and SMD 912.
The SMD 912A output level is from -20 to +5dBm. When feeding the SMD 920 option
upconverter the IF output level is optimal at -10 dBm for any of the modulator models.
The tilt adjustment allows a user to adjust the overall slope of the output spectrum. The range is
selectable from -3 to +3 dB.
RF Output
If the RF L-Band SMD 920 option is installed in the SMD 989
bay, an RF Output section is shown. The header selections
provide quick selection for Mute, Modulating, and RF Level.
Click on the field to activate. When mute is active no output
satellite carrier is output. When the Modulating field is clicked
the output modulation is removed and a carrier only is
transmitted. By clicking the up or down arrows the output RF
level can be increased or decreased incrementally.
By clicking on the “Configure RF Options,” cog a dialog box
appears showing RF output selections as shown in Figure 45.
The output can be set as active or mute. This may also be
toggled by clicking on the Mute field in the Outputs header.
When mute is active no output satellite carrier is output.
The output frequency is settable at a range of 950 to 2150 MHz, When LO Offset is 0MHz.
The LO Offset (MHz) can be entered to allow the desired Satellite Frequency (MHz) to be
entered. The SMD 989 will output the proper frequency to achieve the correct satellite frequency
when combined with the external Upconverter LO (Local Oscillator). This eliminates the need to
determine what the output frequency of the SMD 989 should be to achieve the desired satellite
frequency. In the example settings below the output of the SMD 989 will be the same.
The output level is settable at a range of -30 to 5 dBm. This level may also be incremented to a
higher or lower level using the up/down arrows in the RF Level (dBm) header section.

Figure 45: RF settings
Figure 46: RF settings with 10MHz option
If the RF L-Band SMD 920 option is installed along with 10 MHz BUC Power SMD 94X option the
ability to configure the RF output as well as the ability to enable or disable the 10MHz Ref. Clock
and the BUC Power is also shown. By clicking on the “Configure RF Options,” a dialog box will
appear as shown in Figure 46. Enabling the 10 MHz Ref. Clock or BUC Power will diplex them
with the L-Band PRI RF output looped to the optional SMD 94X LOOP IN.
The parameters shown in blue in the RF Output section indicate the status of that parameter and
cannot be edited in the RF Output configuration window. These statuses are:
- RF Frequency: This is determined by the calculation of the Satellite Frequency and
the L.O. Offset frequency.
- IF Input Level: This indicates OK if the IF input is at the proper level. The Level
indication can be “Low”, “OK” or “High.” If this does not show OK as the status, check
that the IF output is set to -10dBm. If the level indicates LOW or HIGH you may
increase or decrease the IF Level slightly to return the IF Input Level to OK status.
This provides the optimum spectral output performance of the RF upconverter.
- Oscillator Status: Indicates if the 10MHz reference is locked to the incoming IF.
- Output Status: Indicates Present when the output is active, or Missing if the output
is muted.
- Spectral Inversion: This reflects what the RF output will be after the RF
upconverter. This indication changes depending on the Spectral Inversion setting in
the Configure Modulation Options. If the Spectral Inversion is set to Normal in the
modulation configuration, the RF Output will be inverted. If the Spectral Inversion is
set to Inverted in the modulation configuration, the RF Output will be normal.

Failover: This field provides options to enable a Backup Input in the event of a Primary Input
fault. Failover and Restore selection must to applied, after changes select the Apply Changes
field and press the ENTER front panel key.
Failover to backup options include:
Primary Sync Loss
Primary TS Error
MAX BITRATE: 49.4564248 Mbps
Manual Only
TS Sync Loss mode allows the SMD 989 to switch to
backup if the primary input transport sync is lost. In
BAY 1: FAILOVER CONFIG ↕
the TS Analysis mode failover is based on transport
stream errors or sync loss. This allows the SMD 989
to switch to a backup source when there are errors in
the transport stream even if it does not lose sync.
Restore: This field defines the conditions which direct the modulator to return or switch back to
the primary input.
Restore to primary options include:
Primary TS Sync Restored
BAY 1: FAILOVER CONDITIONS↕
Backup TS Sync Loss
Primary TS Error
Manual Only
Primary TS Analysis Restored
BAY 1: FAILOVER CONFIG ↕
Backup TS Analysis Failure
The restore to primary options depend on the Failover
setting. If failover to backu is TS Sync Loss, restore
can be set to Primary TS Sync Restored, or On
Backup TS Sync Loss. The switchover Interval(s) can
BAY 1: FAILOVER CONFIG ↕
be set from 1 to 20 seconds. If switch to Backup is set
to Manual, Restore to Primary can only be set to
Manual.
If TS Analysis Failure (option) is selected, Restore
options are Manual Only on Primary TS Analysis
Restored or On Backup TS Analysis Failure.
Failover conditions can be enabled/disabled and Switch After interval can be set from 1 to 30
seconds.The switch after intervals for each of the TS analysis categories defines a wait time or
delay before the modulator switches to the backup or switches from backup to primary when TS
analysis errors are detected. If the TS Errors are corrected within this time the switch is not
implemented and the TS analysis resumes.
IMPORTANT NOTES: 1. When selecting TS Analysis Failover for Primary or Backup inputs,
the TS Analysis feature must be enabled or active for the respective primary and/or
backup. See the TS Analysis Configuration menu.
3. You cannot use the TS Analysis for failover when you are setup to output VCM or
CCM Multistream with the SMD910 modulator.

Modulator Configuration – Modulator Parameters
The Enter Rate field provides the user a choice of how to setup the modulator’s output Symbol
Rate or Max Bitrate entry fields. The values in these fields are mathematically related depending
on the modulation mode, modulation type, and FEC settings. The SDM 989 contains an internal
symbol rate or max. input bitrate calculator to assist.
It is recommended that you first select the
modulation/FEC code you wish to use.
BAY 1: MODULATOR MODULATION ↕
Enter Rate By
MAX BITRATE: 49.4564248
- Output Symbol Rate
- Input Bitrate
Description: Output Symbol Rate mode allows the entry of the desired output symbol rate. The
SMD 989 calculates the maximum input bit rate and lists it in the Max. Bitrate field.
Description: Input Bit Rate mode allows the entry of a known input bit rate. The SMD 989 then
calculates the needed symbol rate and lists it in the Symbol Rate field.
With output Symbol Rate you enter the desired output symbol rate. It must be mathematically
proper based upon the input bit rate measured by the system. When a higher than needed
symbol rate is entered, the modulator inserts null packets to achieve the rate. When entering a
lower than needed symbol rate the SMD 989 removes nulls, if they exist, from the stream.
With Input Bitrate, the SMD 989 uses the entered bitrate along with the modulation settings to
calculate the needed symbol rate. If it is known that the input transport stream contains a
significant amount of null packets it is possible to enter a bitrate that is lower than the actual input
transport stream bitrate. In this case the SMD 989 will remove existing nulls. Note: There must
be enough nulls in the input transport stream to be removed to allow the lower bitrate or
symbol rate or errors in the transmission transport stream result.
Modulation/FEC: This field selects the modulator’s output modulation type and FEC code for the
selected modulation mode on page 73.
Pilot Insertion (Enabled/Disabled) (Available in
DVB-S2, DVB-S2X Modes)
Description: When enabled, every 16 slots of 90
symbols the modulator will insert 36 non-modulated
symbols to aid in receiver synchronization.
Frame Size (Available in DVB-S2 and DVB-S2X Modes)
- Normal (64,800 bits)
- Short (16,200 bits)
Description: Short frames introduce more overhead but give a shorter encapsulation delay. Short
frames are 4 time shorter than normal frames.
Spectral Inversion: This field sets the spectrum to inverted or normal.
- Normal

bandwidth will be required on the satellite. Rolloff in DVB-S limited to 0.35, 0.25 and 0.20.
Clean Carrier Only (Disabled/Enabled)
Description: When set to Enabled the modulator outputs only a cw carrier for testing purposes.
Rate Adaptation (Disabled/Enabled) Only available in DVB-S2 or DVB-S2X single mode)
Description: When enabled a rate adaption is applied. When disabled the rate adaptatiois not
active. Rate adaptation adds or removes null packets and re-stamps PCRs in order to match TS
bitrate to the modulation payload rate.
PL Scrambling Code (6 digit value entry)
Description: This is used to specify a randomized scrambling sequence applied to each
PL frame and initiated at the end of each PL header. Scrambling randomizes band energy
dispersion and allows for a “signature” when may provide association to a satellite operator or
satellite. The complex code relates to an “n” value defined by an entry of 0 to 262 141.
PRBS (Enabled/Disabled)
Description: When Enabled the PRBS replaces the normal input modulation feeding the
modulator with a PN23 normal or inverted BERT test signal. Select Disabled for normal output
applications.
IMPORTANT: For normal or non-testing applications in which the input is to be used to
modulate the satellite IF or L-Band carrier output, the PRBS test signal must be set to
DISABLED.
