Introduction

1.0 Introduction
The ETS-Lindgren Model 8100-007 RF Power Amplifier can deliver an output
power of 75 W over the frequency range of 1000 MHz to 2500 MHz and an output
power of 100 W over the frequency range of 2500 MHz to 6000 MHz.
The instrument consists of 2 different amplifier lineups, between which can be
switched via coaxial relays. Amplifier band 1 covers the frequency range of 1000 …
2500 MHz and amplifier band 2 covers the frequency range of 2500 … 6000 MHz.
The four-stage solid-state amplifier of frequency band 1 is of modular design and
integrated into two RF modules, both featuring a high linearity and a flat frequency
response.
The five-stage solid-state amplifier of frequency band 2 is also of modular design and
integrated into two RF modules, both featuring a high linearity and a flat frequency
response.
In order to achieve a stable output power, the bias of the amplifier stages are
controlled by low-drift voltage regulators.
The maximum input power for achieving the nominal output power is 0 dBm
corresponding to 1 mW or 0.224 V into 50 . Due to its gain reserve, the amplifier
usually achieves full output power with an input power of -5 dBm.
The final stage is separately protected against overload by current limitation. The
amplifier is protected against open circuit and short circuit at the output. By using
suitable transistors and a special circuit design in the final stage, even a total
mismatch at the output will not cause any damage. For a VSWR 2:1 the maximum
power can be obtained, all specifications being met.
The amplifier housing is designed to ensure minimum RF leakage and high RF
immunity. The module is supplied with DC voltage via RF feed through filters.
In order to protect the amplifier against thermal overload in case the blower fails or
the ambient temperature is too high, a temperature sensor is mounted on the heat
sink in the vicinity of the final stage.

4.0 Before You Begin
CAUTION: Before connecting any components, follow the information
provided in Safety Information on page v.
Setting up the Amplifier
When setting up the amplifier, make sure that the cooling airflow is impeded neither
at the air inlet at the front nor at the outlet at the rear. The permissible operating
temperature ranges from +0°C to +45°C with an air humidity of max. 95%. The outlet
air temperature exceeds the inlet temperature by max. 20°C.
CAUTION: The temperature of the inlet cooling air must not exceed
+45°C. The outlet air temperature should be maximum 20°C higher than
the inlet air temperature.
Rack Mounting
To ensure sufficient ventilation:
Make sure to provide enough space between the casing and the air inlet at
the front panel and the air outlet at the rear.
Make sure that there is sufficient air supply inside the rack (forced ventilation)
and that no overheating can occur due to other instruments placed under or
over the amplifier.
CAUTION: The temperature of the inlet cooling air must not exceed
+45°C.

5.0 Pre-Installation Tasks
CAUTION: Before connecting any components, follow the information
provided in Safety Information on page v.
Mains Connection
The amplifier is equipped with a power supply which can be operated at a voltage of
100–240 VAC. The automatic line fuse (12 A T) is integrated in the mains switch.
Note: When connecting the amplifier to the AC mains network, make sure to
provide a proper protective earth connection according to the regulations.
RF Connectors
The amplifier is equipped with N-type female connectors at all RF connectors. The
mating connectors must be tightened manually.
Interlock Safety Loop
This amplifier permits an interlock safety loop to be connected, which must be always
closed for activating the amplifier. The interlock function protects the user against
unintentional emission of RF power.
It is necessary to wire the attached mating connector for the Remote Control and
Interlock connector at the rear panel of the instrument as shown below. Pin 8 and pin
15 should be connected to the safety loop of the measuring room.
Figure 2: Pin assignment of remote control and interlock connector
This ensures that the amplifier can only be switched on when the safety switch, and
thus the door of the measuring room, is closed.
Page 18
18
Pre-Installation Tasks
www.ets-lindgren.com
The EXTERNAL INTERLOCK and EXTERNAL INTERLOCK RETURN contacts are
designed as floating ones. In this way more than one amplifier can be interconnected
in an interlock system with a common switch or a common loop.
Figure 3: Example of interlock safety loops
If this safety function is not used after thorough examination, the interlock contact can
be bridged in the Remote Control and Interlock connector. This is done using a
jumper from EXTERNAL INTERLOCK pin 8 to EXTERNAL INTERLOCK RETURN
pin 15.
Note: If the interlock connection is missing, the amplifier cannot be operated.
Finally, check that there is no message indicating an interlock error status on the
display. Now the amplifier is ready for use and can be operated either manually via
the front panel or via one of the remote control interfaces.

If the interlock loop is interrupted during operation, the amplifier is
deactivated automatically. The error message Interlock External will be
displayed. If the door and thus the safety switch are closed again, the
amplifier is not activated again automatically but must be activated via
the front panel or via one of the remote control interfaces.
After a measurement has been concluded, the amplifier can be
deactivated by pressing the Amplifier key again. RF OFF will be shown
at the display. For removal of the internal heat the fan can be operating
for about one more minute.
CAUTION: If the amplifier is driven outside its frequency range, no
damage is caused; however, only the signal component (e.g. harmonics
of generator), which lies within the frequency range of the amplifier, is
amplified.
In this case, measuring the output power does not provide any
information on the actual operation of the instrument.

DEVICE MESSAGES
Device messages (to IEC 625-1) are transmitted on the data lines, in which case the
ATN line is not active, i.e. high. The ASCII code (ISO 7-bit code) is used.
Commands Received by the Amplifier in Listener Mode
(Controller to Device Messages)
The ASCII code (ISO 7-bit code) is used. All commands to the amplifier
consist of a single character set followed by the "Line feed" character
(hexadecimal: 0A; decimal: 10) as a terminator.
All commands to the amplifier must be terminated by a terminator. The only
permissible terminator is:
<Line feed> (ASCII code 10 decimal)
A command line may require more than one line on the screen of the
controller because it is only limited by the terminator. Most controllers
automatically append a terminator to the transmitted data.

Messages Sent by the Amplifier in Talker Mode
(Device to Controller Messages)
The amplifier transmits messages via the IEEE-488.2 GPIB-bus if it has been
requested by a query command to provide data in its output buffer and has
been addressed as talker.
Note that the command line with the data requests must be transmitted
immediately before addressing as talker. The output buffer is cleared if
another command line is entered in between.
Transferring the Device Status
The status messages of the amplifier indicated at the display on the front
panel are transferred as a text via the IEEE-488.2 GPIB interface to the
controller. For this purpose, the status text must be polled first (see control
character sequence above). The text can then be transmitted in a standard
reading process. The amplifier transfers the text also with "Line feed" as the
terminator.

Figure 12: IEEE interface status messages
Alarms
If a fault status occurs, the amplifier indicates the specific fault message and
sends a service request via the IEEE interface. The controller is able to
recognize this alarm message without having to poll the status byte of the
amplifier repeatedly.
To reset the fault message the command *RST has to be sent to the
amplifier.
The alarm message has to be acknowledged by way of the serial poll
procedure specified in the IEEE-488.2 GPIB standard (see interface manual
of the controller). The status byte issued by the amplifier corresponds to the
above-mentioned status messages.

Figure 13: Pin configuration of the Ethernet interface
On power on, the amplifier is always in the local state (manual operation). At the front
panel display LOCAL will be indicated.
If a controller addresses the amplifier as a listener by sending the REMOTE
command, the amplifier changes to the remote state and remains in this state even
after termination of data transmission. This is indicated by the message LAN at the
front panel display.
A change of the control mode is only possible when the amplifier is in STANDBY
mode.
There are two methods to return to the local state:
By the command LOCAL.
By pressing the Control key on the front panel of the amplifier.

ADMINISTRATION BY LAN
Default IP Address of the Ethernet Interface is 192.168.1.253
The Ethernet interface can be configured for the first time by LAN only if the
client computer / local network is matching this address range and subnet
mask. Only one new Ethernet interface can be plugged on the LAN at a given
time, until an individual IP address is assigned on each Ethernet interface;
otherwise, conflicts will be caused.
Computer Configuration
Configure computer with:
IP address 192.168.1.xxx where xxx = 253, and
subnet mask 255.255.255.0 are assigned by default.
Check that computer is connected to same Ethernet LAN than the Ethernet
interface.
TCP/IP Configuration
IP address of each Ethernet interface must be unique on the network. An
individual address can be either assigned by:
A static address using administrative commands, or
An existing DHCP server on the network, who can assign an available
address.
If both DHCP and static IP address are defined, DHCP configuration will
override static IP.
TCP/IP Configuration Setup
Open web browser.
Enter IP address of Ethernet interface (e.g. http://192.168.1.253).
Enter user and password (8 digits), default user ”user” default password
"admin00", and the following page will display:

ETHERNET CONTROL COMMANDS
The ASCII code (ISO 7-bit code) according to Figure 10 of this manual is used. All
commands to the amplifier consist of a single character set followed by the "Line
feed" character (hexadecimal: 0A; decimal: 10) as a terminator.
All commands to the amplifier must be terminated by a terminator. The only
permissible terminator is:
<Line feed> (ASCII code 10 decimal)
Between each two commands there should be a delay time of 200 ms to avoid a
command overflow situation.

Figure 16: Signals at the remote control and interlock connector
All commands and messages, which are available on the front panel, can also be
found on the remote control interface. The status messages for all faults are
combined to a summary alarm on the interface.
The remote control interface commands are activated by negative slope triggering.
(The pulse width should be 10 to 50 ms.) This is done in order not to activate the
amplifier immediately on power-on by static remote control interface commands (TTL
REMOTE and OPERATE). Triggering on the negative slope permits to control the
interface by 12 V CMOS logic or 5 V open-collector TTL logic.
The status output MAINS ON supplies a maximum current of 100 mA at 12 V in order
to be able to activate and feed other equipment, or, for example, an external interface
and similar devices together with the amplifier.
The amplifier can be set to remote control mode and back to local control mode by
using the command TTL REMOTE. At the status display the text will change from
LOCAL to TTL. Now the amplifier can be activated using the command OPERATE.
The indicated message must then change accordingly from STANDBY to OPERATE.
