About this Manual
This manual is part of the documentation for the NX8000 family of transmitters from Rohde
& Schwarz. Each transmitter and each transmitter component is described in a separate
manual. The individual manuals of the family of transmitters are modular in structure and
complement each other.
Structure
Each transmitter component is described in a separate manual and can thus be used as an
individual component (where practical). The transmitter manual is the main document for
the entire set of documentation. It describes all steps that are necessary to install a transmitter, put it into operation, operate and maintain it. Where applicable, the transmitter manual refers to the individual manuals for the various components. The component manuals,
in turn, also refer to the transmitter manual whenever the component is to be used as a
transmitter module.
Contents
The manuals for the family of transmitters describe all steps required to install the transmitter or one of its components, put them into operation, operate and maintain them, troubleshoot and service them. The Annex includes interface descriptions plus technical
documents.
For convenience, all manuals are structured identically. Sections that are not relevant to the
manual at hand are also included but are left blank.
Safety
All skilled personnel working with a transmitter or its components must read all relevant
manuals and comply with the safety measures that are detailed in the chapter about safety
and in the applicable sections in the manual. The transmitter and the individual transmitter
components must be used only for their intended purpose. All operations involving the
transmitter or individual transmitter components must be performed by skilled personnel.
The manual will point out specifically if additional qualifications are required.
Symbols and Layout
The triangular warning symbol indicates danger. In addition to the triangular warning symbol, different key words indicate the level of potential danger.
Instructions are given in numbered steps or indicated by an "index finger" symbol to the left
of the instruction text. The results of the performed instructions are indented.
The key word "Note" precedes notes. Notes contain additional information and tips to help
facilitate the work at hand.
All other formatting options add structure to the text and are self-explanatory.

Safety Instructions
Safety Instructions for Transmitter Systems
and Instruments
ATTENTION!
The safety instructions provided in this manual must be complied with!
Pay special attention to the following points:
 Only skilled personnel may perform electrical installation and electrical connection
tasks.
 Always follow the relevant national and international safety rules and regulations when
equipping operating areas and when setting up and operating electrical equipment.
These rules and regulations include for example:
– Protective measures to prevent accidents
– Protective measures to prevent overvoltage
– Insulation status of electrical equipment
– Grounding of electrical equipment
– Physical properties and laying of electric lines and cables
– Regulations applying to industrial premises and areas as well as to special facilities.
 When setting up the rack, observe the country-specific rules for accident prevention, for
example with regard to:
– Risk of getting crushed when working with loads suspended in the air
– Risk of falling off ladders
– Risk of injury when lifting heavy objects.
 Use your personal protective equipment for installation and repair work, i.e. wear pro-
tective clothing such as helmets, safety gloves and eye protection, depending on the
task at hand.
 Operate the equipment and systems only when the cabinet is closed. If you have to open
the cabinet for maintenance and repair work, comply with the applicable safety instructions.
 If the equipment and systems are removed from the AC power supply, all poles must be
disconnected. Check for and remove any external power supply, i.e. all measuring cables, extension cables, multiple socket outlets (except for special service sockets). Wait
for five minutes to ensure that any and all capacitors are sufficiently discharged.
 Additionally with liquid-cooled transmitters:When filling and installing the cooling system
(pump unit and heat-exchanger unit), observe the rules for handling hazardous substances (cooling agents); see section "safety data sheets about hazardous substances"
under "EU safety data sheet in accordance with 2001/58/EC Antifrogen".

Safety Instructions
General Safety Instructions
This section contains general safety instructions that apply to all products manufactured or
distributed by Rohde & Schwarz.
In accordance with IEC 215 and EN 60215, transmitters and their auxiliary equipment must
be operated only under the responsibility of skilled personnel. The EN 60215 standard
("Safety requirements for radio transmitting equipment") defines the minimum requirements
for skilled electrical personnel.
Complying with all statutory provisions is a precondition for operating radiocommunications
systems and equipment. The operator or the operator's authorized representative is responsible for ensuring compliance with these guidelines. They must also ensure that the
operating personnel meets the applicable country-specific training requirements. These requirements also include any periodic training that is necessary.

Special Danger Warnings
4.1
Hazards due to AC Supply Voltage
Safety Instructions
There is a risk of electric shock with any Vrms > 30 V AC or V > 60 V DC voltage. Appropriate measures must be taken to prevent exposure to any danger when working with voltages
that bear the risk of electric shock. Never work on live parts unless specifically required and
only if the special safety precautions are complied with.
4.1.1
AC Power Supply
 Before connecting the equipment to the AC power supply, make sure that the AC supply
data specified on the system or equipment matches the rated data of the local AC supply. The supply circuit must be protected by fuses against overloading and short circuits
at all times.
 Miniature modules have neutral conductor fuses. As a result, the power supply may still
be connected even after interruption of the circuit by a fuse.
4.1.2
Replacing Fuses
 Replace the safety fuses accessible in the operator area only if no voltage is being ap-
plied to the instruments. The safety fuses may be replaced only by fuses with identical
electric data, identical switching characteristics and identical switch-off capacity.
 Motor and line circuit breakers accessible in the transmitter's operator area may be op-
erated. If their response range is selectable, do not change the settings made by the
manufacturer. If the settings are accidentally changed, reset them by using the correct
values specified in this documentation.
4.2
Hazards due to High-Energy Circuits
The instruments include low-voltage circuits which can be fed from an extremely low-impedance voltage source (e.g. amplifier operating voltage). These circuits conduct dangerously
large amounts of energy. We handle these circuits in the same manner as circuits with voltages that bear the risk of electric shock. They are usually covered and thus protected
against accidental contact. The cover comes with a warning label.
Practical experience has repeatedly shown that a short circuit caused by metal tools can
cause severe burns. For safety reasons, high-energy circuits are protected by covers and
are thus not accessible within the operator area of the instruments.
2095.7346.32
- 1.4 -
E-3
Chapter 1
Safety Instructions
 If you need to measure low-impedance voltages, during repair work for example, exer-
cise the same caution as when measuring operating voltages that bear the risk of electric shock.
Wear protective clothing if necessary.
 Before you open an instrument or remove its cover, switch off the operating voltage and
wait for five minutes to ensure that any and all capacitors are sufficiently discharged.
 Do not short-circuit capacitors to discharge them.
4.3
RF Hazards
4.3.1
Mandatory Training
 Operators must instruct their personnel on how to use this transmitter or instrument in
accordance with EN 60215 and IEC 215. This periodic training must cover the radio-frequency hazards of the individual transmitter or instrument. Only after such training has
been provided and documented may the operating personnel handle switching and operating tasks.
High-energy RF circuits within the transmitter or the instrument are routed via conventional
detachable RF connectors (e.g. N). Depending on the output power, the transmitter or instrument outputs come with screw-in or pluggable RF lines or ducts.
If RF lines or modules conduct high power, the connection point or the entire module is
marked with the standard warning symbol (yellow triangle with black exclamation mark).
4.3.2
RF Shielding
Transmitters and instruments from Rohde & Schwarz are shielded in such a manner that
RF radiation does not pose any danger even in the immediate vicinity if all RF lines are
closed. This statement is based on the ordinance for electromagnetic fields as defined in
German law:
The 26th ordinance for the Federal Emission Protection Law dated December 16, 1996 defines limit values for radio-frequency equipment for electric and magnetic field strengths.
4.3.3
Rules for Operating an Amplifier
Opening RF lines during operation may cause electric arcs. This can cause burns and eye
injuries.
 Operate the amplifier only if an antenna or dummy antenna is connected.
 Never undo RF lines during amplifier operation.
 Never open amplifiers or modules during amplifier operation.
 Never put amplifiers into operation if RF lines are open.

4.3.4
Safety Instructions
Rules for Working with an Open Amplifier
Operating the instrument with RF power is not permitted if the instrument has been opened
or its covers removed.
4.4
Hazards due to Beryllium Oxide (BeO) Ceramics
Note
Instruments and modules with components containing beryllium oxide (BeO) ceramics are
marked accordingly. The following applies:
If handled correctly, parts or components containing BeO ceramics are not hazardous to
health.
If used improperly, however, BeO dust may be released. BeO dust causes chronic lung disease (berylliosis); inhaling large amounts over an extended period of time is toxic, causing
respiratory paralysis and death.
4.4.1
Rules for Handling BeO Ceramics
 Parts or components containing BeO ceramics must not be opened, mechanically pro-
cessed or destroyed.
 Above all, these parts or components must not be scratched, broken, ground, tempered
and sandblasted, not even under exhaust hoods.
4.4.2
Marking Parts or Components Containing BeO Ceramics
Rohde & Schwarz marks all parts or components containing BeO ceramics in the electric
parts list, the circuit diagram and the transmitter.
The electric parts list contains the following text:
Beryllium oxide
Hinweise beachten
Observe instructions
The circuit diagram includes the full warning:
Achtung!
Hinweise zur Sicherheit beim Umgang mit Teilen aus Berylliumoxid-Keramik beachten!
Attention!
Observe safety instructions for handling parts made from beryllium oxide ceramics!
In the transmitter, all components containing parts made from beryllium oxide ceramics are
marked with a warning symbol and a label:

Design and Characteristics
Device Purpose and Overview
R&S XLx8000 transposers/gapfillers receive the off-air signal from a master emitter and radiate it further to an SFN or MFN network. The signal is converted for modulation standards
DVB(-T/H), ATSC, DTMB and MediaFLO (DTV) or B/G, M/N, I (ATV) in the UHF or VHF frequency range and for DAB in the VHF frequency range.
Note
The transposer characteristics comply with the relevant standard specifications and EN
standards, thus meeting international requirements.
The transposers, which are integrated in a compact 19" housing, are designed for lowmaintenance and uncomplicated operation. All parts inside the instruments are maintenance-free. Automatic functions such as loading previously stored precorrection curves on
changing channel make operation extremely easy. Precorrection by the user is unnecessary.

RF ON/OFF
Switches transmission mode ON or OFF. If transmission mode is free of
interference, the instrument produces RF power.
LOCAL
Switches between local and remote operation
With local operation, settings are entered either on the front panel of the
instrument or via a PC which is connected to X30 (ETHERNET
LOCAL).
With remote operation, settings are made via a logged-on network client
which is connected to the X31 interface (ETHERNET REMOTE).
2.3
LED
Meaning
RF ON/OFF
LED (green) signals transmitter operation. If the instrument is producing
power, the RF PRESENT LED also lights.
LOCAL
LED (yellow) signals local operation. The instrument can no longer be
operated remotely.
RF PRESENT
LED (green) signals that RF is present at the output. The LED goes out
if the output power drops below a fixed threshold.
WARNING
LED (yellow) signals a general warning from the instrument.
FAULT
LED (red) signals a cumulative fault on the instrument.
CompactFlash Card
The settings for the instrument operating parameters are written to a CompactFlash memory card. The parameters can be transferred quickly from one device to another (e.g. a replacement device) by simply swapping the memory card.
2.4
Fan
The instrument has a fan which draws in cool air via the ventilation openings in the front
panel and blows the warm air out via the rear panel.
2100.4445.32
- 2.9 -
E-2
Chapter 2
Design and Characteristics
The fan is mounted on the outside of the rear panel and can therefore be changed without
opening the cover on the instrument.
If a fan fails a warning message is generated. If the temperature then increases too much,
a fault message is output and the instrument is shut down in order to prevent the electronics
from overheating.

The local time is the time of day or zone time applicable at the station.
Unlike universal time (UTC = universal time coordinated), there is a positive offset for time zones east of Greenwich or a negative offset for time
zones west of Greenwich.This offset is determined by the time zone and
is always a multiple of a full hour or sometimes of a half hour.
In some countries, the clock is set forward by 1 hour in summer (daylight

Window Offset
An echo that results from the transmitted signal being fed back to the
transposer input has a delay which is at least the same as the signal
turnaround time through the transposer.
The Window Offset parameter enables the position of the echo compensation window to be moved back in order to take account of echo delays
due to external influences (e.g. echo from an adjacent SFN transmitter).
Echo Level Limit

Introduction to Operation
The R&S XLx8000 transposer can be operated as follows:
– Local operation via the display and menu keys on the front panel of the device
– Operation via the web browser
– Monitoring and control via SNMP
If the unit is operated via the web browser of an attached PC/client computer, two modes
are possible:
– Direct operation via a locally connected PC
– Remote control via a remote network client
1.1
Authorizations and Menu Levels
There are different authorizations and menu levels for operating the instrument.
 Authorizations define which parameters and configurations you are allowed to change.
 The parameters to be selected are on a maximum of four menu levels.
1.1.1
Authorizations
Various authorization levels protect against unauthorized access to critical system settings.
In local operation via keyboard and display you work by default with the factory preset user
ID Operation (which authorizes you to make settings that directly affect transmitter operation).
Note
You can change, create or delete user profiles with the aid of the user administration facility,
which you call up via the web browser (see section "User Administration").
From the Change User context menu, you can log on in any menu under a different user
ID. No password is required to change the user ID under local control (according to the factory default). You can also protect access to the display by entering a password.
Fig. 1 Changing user at display in local operation mode
You can select a user profile by clicking Select user from list.
The following factory-default user profiles are available for local operation:

change his/her own password via the user administration program.
Note
In the event of a power failure, the instrument resets to the Operation authorization level.
Local mode
Fig. 2 LOCAL key (with LED) for switching between local and remote operation
For local operation the instrument must be in local mode, so that changes to individual
menu items via the instrument keypad and display, or via a PC connected to ETHERNET
LOCAL (X30), will be accepted.
To switch to local operation, press the LOCAL key (the associated LED lights up).
Remote operation
For remote operation the instrument must be in remote operation mode, so that commands
for changing settings via the ETHERNET REMOTE (X31) interface will be accepted.
To deactivate local operation, press the LOCAL key again (the associated LED goes out).

Connecting a PC/network
 For operation by PC connect a PC by RJ-45 cable to the X30 (ETHERNET LOCAL) port
on the R&S XLx8000.
 For remote control connect the remote monitoring network by RJ-45 cable to the X31
(ETHERNET REMOTE) port on the R&S XLx8000.
Setting IP addresses in the transposer
To allow the R&S XLx8000 to communicate with a local PC or remote network client, the IP
address of the used Ethernet interface of the transposer must be in the IP subnet of the PC
or remote monitoring network.
You can directly enter the address data needed for communication via the XLx8000 display.
Note
Alternatively, you can also adapt the IP address of your PC to the subnet of the transposer
under Windows and retain the factory setting for the local network interface X30 (IP address
= 192.168.57.253, network mask = 255.255.255.0). In this case, configure the network address of your PC to, for example, 192.168.57.100/255.255.255.0.

Monitoring and Control via SNMP
SNMP (Simple Network Management Protocol) is used for monitoring and controlling a
wide variety of different units in a network. Detailed information about this topic can be
found under http://www.wikipedia.org/.
A description of the unit - the MIB (Management Information Base) - must be loaded in the
central unit ("manager") from which the transmitters are monitored.
A monitored unit contains a program ("agent") which can answer queries from the manager
and execute commands. Furthermore, the agent may of its own accord generate a message and send it to the manager. In this way, the central unit can be informed of a fault.
1.5.1
Installation
The MIBs required for monitoring and controlling a transmitter are stored as a ZIP archive
directly in the transmitter control unit and can be downloaded from there using any networkcompatible unit. All of the information required for configuration is contained in the MIBs
themselves.
When the transmitter is put into operation, both the agent in the transmitter and the manager must be configured. Additional steps may be necessary if the transmitter is connected
via routers, firewalls or similar devices as they may block data packets.
 The XX8000 transmitter family supports the versions SNMPv1 and SNMPv2c.
 Alarms can be sent as v1Traps, v2Traps or v2Informs.
 Several destinations can be set for fault messages (alarm sinks).
 Several communities can be set with Read Only authorization and Read/Write authori-
zation.
1.5.1.1
Settings on Transmitter Side
You can make settings yourself via the local display (if available), the web server or SNMP.
The menu windows of the SNMP menu contain all the settings that are required for accessing a transmitter.
Note
2100.4445.32
Changes to these settings are adopted immediately. The device does not need to be restarted.

Chapter 5
Operating
Note
Detailed information about the individual parameters can be found in the descriptions of the
respective menu windows.
1.5.1.2
Settings on Manager Side
In order to monitor and control a transmitter with SNMP, you need on the manager side the
MIB of the instrument and a program that the MIB can interpret.
You can load all available MIBs from each instrument with the aid of a web browser.
1. Log on using the web browser and select the SNMP Administration menu.
MIBs from Rohde&Schwarz and IRT are available. MIBs from IRT allow transmitters to
be linked using SNMP irrespective of the manufacturer. They are, however, limited with
respect to their functionality. When using IRT MIBs, you can select the "Inhibit Status"
for local operation (in the same way as for the parallel contacts). If this function is activated, no alarms/traps are sent when the transmitter is in local mode. You can activate/
deactivate this function using Inhibit Status in the SNMP > General menu window.
The MIBs have the naming convention RS-XX8000-<TV/Radio Standard>-<Standby
Concept/Option>-MIB. An example is RS-XX8000-ATV-TX-MIB for signal transmitters
for analog TV.
Examples of MIBs and contents:
MIB
Description
RS-COMMON-MIB
Contains general Rohde&Schwarz definitions
RS-XX8000-COMMON-MIB
Contains definitions that comply with all the transmitters of the
XX8000 generation (e.g. type plate, configuration)
RS-XX8000-TRANSPOSER-MIB
Contains definitions for single transposers
2. Save the required ZIP file to your PC.
3. Load the following MIBs:
a) RS-COMMON-MIB

Chapter 5
Operating
b) RS-XX8000-COMMON-MIB
c) MIB of the standby concept or option
A detailed description of the MIBs, the information that they contain and the associated options is given below.
1.5.1.3
Testing SNMP Communication
SNMP communications is properly set up if you have loaded the MIBs in your program and
you are using the correct IP address of the transmitter and the correct community. For queries and settings you must set the SNMP version in your manager; the transmitters detect
the used protocol automatically.
The following query can be used as a simple test:
In the example above, a transmitter with the IP address 10.123.10.7 queries the OID (ObjectIdentifier:
unique
designation
of
a
data
point)
serialNumber
(.1.3.6.1.4.1.2566.127.1.2.167.1.1.1.2). The reply from the agent is 100111.
Using a further test, you can check whether the transmitter sends an alarm message in the
event of an error and whether this message reaches the alarm destinations. To do so, set
an OID sendTestTrap (.1.3.6.1.4.1.2566.127.1.2.167.1.1.2.3) to the value 2, which triggers
a testTrap (.1.3.6.1.4.1.2566.127.1.2.167.1.2.0.1). This alarm is sent to all receivers which
have been entered for the alarms (Trapsinks, see above).
This type of fault message functions in a slightly different way than that used for querying
and setting values (default: UDP Port 161 for SET/GET and UDP Port 162 for alarms).
2100.4445.32
- 5.27 -
E-2
Chapter 5
Operating
The following illustration shows that the testTrap has been received correctly by the unit
with the serial number 100111.
Known problems
If querying the data does not work or if you do not receive an alarm, check the following:
– Has the network been connected correctly? Does the SNMP connection function exclusively via the remote Ethernet interface of the device (R&S NetCCU800: X5 – NETLINK,
R&S Sx800/SX801: X2, R&S xLx8000: X32 – ETHERNET REMOTE)?
– Are the network settings (IP address, gateway) correct?
– Has the correct Community been entered for accessing the manager and the transmitter
(case-sensitive)?
– Is a PC firewall blocking incoming SNMP packets?
2100.4445.32
- 5.28 -
E-2
Chapter 5
Operating
– Has the program which receives alarms been started and correctly configured?
– In large networks: Is a router or firewall blocking the SNMP packets?
– Is message suppression (Inhibit Status in the SNMP > General menu) activated?
1.5.1.4
Configuration
This chapter provides an overview of the available properties.
RS-XX8000-COMMON-MIB
This MIB contains general data that supports every unit:
– Type plate: serial number, software version, etc
– SNMP configuration: table for alarm destinations and alarm versions
– Triggering of a test trap
– Counter for counting the transmitted traps
– List of the alarm messages last transmitted
– Parameters which are used in several other MIBs
This information always applies to the instrument that is being monitored via SNMP.
Setting alarms
The transmitter-specific alarms offer an extensive range of configuration possibilities.
Depending on the available system, it is possible to set detailed alarms: for example, for
every item of status information in every amplifier in every rack of every transmitter in a medium-power n+1 system. In addition, it is also possible to assign a freely selectable priority
and to check the current status.
In the illustration above, the following information is contained in the highlighted row (depending on the used MIB; here: DVB n+1 medium-power system):

Mute on PPS Fail
Used to determine the behavior in SFN mode in the event of failure of
the external time reference. The following settings are possible:
– off: The output signal is not suppressed
– only at startup: The output signal is suppressed at startup until a valid
1 pps signal is detected; if the 1 pps signal fails after successful synchronization, the output signal is no longer suppressed
– after fail delay time: The output signal is suppressed if the 1 pps signal fails for longer than the period specified under Fail Delay Time
This is the recommended setting for operation in SFN mode.
Mute on Ref. Fail
Used to determine the behavior in SFN and MFN mode in the event of
failure of the external reference frequency source. The following settings
are possible:
– off: The output signal is not suppressed
– only at startup: The output signal is suppressed at startup until a valid
reference source is detected; if the reference source fails after successful synchronization, the output signal is no longer suppressed
– after fail delay time: The output signal is suppressed if the reference
source fails for longer than the period specified under Fail Delay Time
This is the recommended setting for operation in SFN mode.
Fail Delay Time
If a reference source fails, the time specified here must elapse before
the output signal is suppressed. The setting is effective if "after fail delay
time" is set under Mute on PPS Fail or Mute on Ref. Fail.
Selection: 0 to 24 hours; 0 hours = no delay time
8.1.1
Reference Frequency Source
The basis for frequency generation is a 10 MHz oven-controlled crystal oscillator (OCXO).
This OCXO can be operated in different modes:
"Internal" mode
The OCXO runs in uncontrolled mode.
It obtains its control voltage via a D/A converter which can be set using the OCXO adjust
setting item. This allows the OCXO frequency applied at the test output REF OUT (X29,
rear panel of the transmitter) to be adjusted to 10 MHz where necessary.
"External 5 MHz" and "External 10 MHz" modes
The OCXO runs in controlled mode.
Due to the control, the control voltage generated by the D/A converter is adapted on an ongoing basis so that the 10 MHz frequency of the OCXO is synchronized with the externally
supplied 5 MHz or 10 MHz reference frequency.
2100.4445.32
- 5.50 -
E-2
Chapter 5
Operating
"External 1pps" mode
The OCXO runs in controlled mode.
The 10 MHz frequency of the OCXO is synchronized with the external seconds pulse. In
this mode, for example, SFN operation is possible without separate feed of a 10 MHz reference.
"Internal GPS" mode
The OCXO runs in controlled mode.
The 10 MHz frequency of the OCXO is synchronized with an optional internal GPS receiver.
8.1.2
Holdover Mode (for Failure of the Reference Frequency)
As soon as a failure of the external reference frequency is detected, the control voltage for
the OCXO is no longer modified. The result of this is that the RF generation is now based
on the stability of the OCXO.
As soon as the external reference frequency is restored, the control voltage on the OCXO
will be controlled again with the externally supplied reference frequency.

TV Settings > Reference > GPS Submenu
The menu windows in the TV Settings > Reference > GPS menu contain information for

Adjusting the I/Q Modulator
Note
Before performing the adjustment, make sure that the transposer has been in operation for
at least 30 minutes (operating temperature).
Objective
If quadrature modulation were optimal (theoretically possible), the residual carrier would be
completely suppressed. In actual practice, however, residual carriers arise (e.g. due to
crosstalk). They must be suppressed using suitable correction carriers.
The objective of I/Q adjustment is to suppress the undesired center carrier and undesired
carrier in the sideband with respect to a test carrier by better than 60 dB.
Two methods are available
Two methods are available to perform the I/Q adjustment: setting and testing actuators
manually or via a convenient automatic process.
The automatic method will usually meet the requirements. Yet, it may sometimes be useful
to test the automatically determined values for the actuators and to improve them.
4.1
Automatic Adjustment
1. Call the TV Settings > RF Out > IQ Adjust menu.
2. Under Auto I/Q Adjust, select the setting Start and confirm with OK.
The automatic process starts and the status display under Auto I/Q Adjust is changed
to In Progress. In this state, transmitter parameters can no longer be changed. Moreover, the output signal is suppressed during the calculation.
After approx. 5 minutes, the status will change (again) to Adjusted. Automatic I/Q adjustment is then completed and the determined actuators will be displayed under Bias
Course, Bias Fine, Gain and Phase.

Implementation
1. Set the Bias Fine [I/Q] actuators to zero.
2. Course adjustment, center carrier: Using the Bias Coarse [I/Q] actuators, suppress the
undesired center carrier as much as possible with respect to the test carrier. You should
individually adjust each actuator going back and forth several times until you achieve an
optimum value.
3. Sideband adjustment: Use the Gain [I/Q] and Phase actuators to suppress the undesired carrier in the sideband by more than 70 dB with respect to the test carrier. You
should individually adjust each actuator going back and forth several times until you
achieve an optimum value.
4. Course adjustment, center carrier optimization: Using the Bias Coarse [I/Q] actuators,
suppress the undesired center carrier as much as possible with respect to the test carrier. You should individually adjust each actuator going back and forth several times until
you achieve an optimum value.
5. Fine adjustment, center carrier: If the center carrier is suppressed by less than 70 dB,
carry out a fine adjustment using the Bias Fine [I/Q] actuators.
