2.3 Function of the Upconverter
2.3.1 Main Modules
The Upconverter has a modular structure. The unit consists of four main parts, the Upconverter module, the
main power supply, the master communication module (Main controller) and the user interface.
The Upconverter module includes all components (local oscillators with synthesizers, OCXO-reference, mix-
ers, filters, amplifiers), which are necessary for a dual conversion Upconverter.
The switched mode power supply delivers a +24 V DC voltage to the master communication module.
The master communication module controls all other modules within the device and distributes 24 V DC,
6.5 V DC and -4 V DC to all other modules within the Upconverter module and the display/keypad. The mas-
ter communication module gets its inputs via the remote interfaces or the keypad.
The user interface consists of a keypad, a LC display for local control, a serial interface (RS485/RS232) and
an IP over Ethernet interface for remote control. The Upconverter functions can be controlled either locally or
remotely.
Figure 1 indicates the main function blocks of the Upconverter including the main external interfaces.

2.3.2 Signal Flow
The input signal at 70 MHz, 140 MHz or 720 MHz passes first through an IF amplifier. This amplifier unit is
equipped with a gain variation of 30 dB with 0.1 dB step size. For compensation of transmission line charac-
teristics, an adjustable gain equalizer is integrated within the IF-amplifier.
The output signal of this amplifier is converted within the 1st mixer to a fixed IF frequency at typically
2.45 GHz (or 2.44 GHz). The local oscillator fixed LO feeds the mixer with the LO signal. At this IF frequency
a linear phase filter selects the correct mixer output signal. This filter has a very low group delay distortion.
In the 2nd mixer the IF signal at typically 2.45 GHz (or 2.44 GHz) is converted directly to the output band. The
microwave local oscillator MW LO feeds the mixer with a wide tunable LO signal. A multi-loop synthesizer
consisting of a coarse synthesizer and a fine step synthesizer generates the MW LO-signal. The reference for
this synthesizer is either an internal 10 MHz OCXO or an external 5 MHz or 10 MHz reference signal. The
step size of 100 Hz is at every MW LO Frequency an exact ratio of 10 MHz/105.
The output signal is filtered by a microwave band pass filter and passes then through an output amplifier.

2.3.3 Local Oscillators
Both local oscillators are built with PLL-Synthesizers. The synthesizers use an internal reference of 90 MHz.
This 90 MHz Reference is direct synthesized by multiplication of a 10 MHz OCXO. To synchronize multiple
converters in LO-phase it is also possible to phase-lock the internal 10 MHz OCXO to an external reference.
The frequency of this external reference can be either 5 MHz or 10 MHz.
Several frequencies and frequency ranges for the RF output signal, the LO signals and the IF input signals
are listed in Figure 4.

2.3.4 Warm Up Period
When the converter is powered on, it takes some time to boot the firmware (approx. 1 minute). After booting
some time is required for the oven controlled crystal oscillator (OCXO) to warm up. Only after sufficient warm
up the specified maximum frequency offset is established. Therefore a warm up time is foreseen, during
which an oven cold warning is generated. The signal path is automatically switched off if the unit is in warm
up period. In this case the “TX On” LED is orange instead of green when the unit is configured for TX on.
2.4 Power Supply
The power supply has the following main parameters:
·Switched mode power supply for industrial application
·Standard Input voltage range is 90 V…264 V AC (50…60 Hz)
·Output Voltage: 24 V, max 2.0 A (Ta = 50 °C) / 1.2 A (Ta = 70 °C)
·Efficiency typical: > 86 %
·The power supply is protected against overload and short circuit operation.
·Recommended mains fuse: 3.15 A or 2 A (as indicated on unit).

2.7 Connectors on the Rear Panel
2.7.1 Mains AC Input Connector Block
The mains AC input connector block includes a male power input connector according to IEC/EN 60320. It
also includes two mains fuse (type 5 x 20 mm). The allowed ranges for the AC input voltage, the input fre-
quency are printed on the label near the connector block.
2.7.2 Alarm Interface
The alarm interface connector is located on the rear panel. The alarm interface has 2 alarm outputs and an
input for a “Hardware Mute” signal (RF-Inhibit). Two relay contacts are used for the alarm outputs.
The mute input signal is processed by the controller. This input is a 5 V TTL input with internal pull up. If mut-
ing via this input is enabled by software a low level (or connection to ground) enables the output of the con-
verter and a high level (or open input) disables the output of the converter.
Important: When the “Hardware-Mute” is enabled by software or front panel setting, pin 4 and pin 9
must be connected for normal operation!

The serial interface can be configured to the following baud rates: 4800, 9600, 19200, 38400, 115200 Baud.
The following data formats are allowed: 7E1, 7O1, 7N2, 7E2, 7O2, 8N1, 8E1, 8O1, 8N2 (Number of data bits,
parity, number of stop bits).
For the RS 485 twisted pair signals a 100 Ohm capacitive coupled (100 nF) termination can be activated
individually for the Data In (RX) and the Data Out (TX) signal pairs.
The factory default is set to RS232, baud rate 19200 and 8N1.
2.7.5 Ethernet Interface
In addition to the serial interface an Ethernet Interface can be installed for remote Monitoring and Control.
This interface supports 10 or 100 Mbit/s Ethernet in full duplex or half duplex mode.
The link LED indicates if there is a physical link established to this connector. Auto negotiation according to
IEEE 802.3 / 802.3u is used to detect the highest possible link speed and full duplex or half duplex mode.
The link LED is green, if there is an active link. The LED briefly goes dark during data transfer.
The speed LED is yellow if there is a 100 Mbit/s link established. The LED goes dark if there is a 10 Mbit/s
link established.

The configuration of the IP Address, Subnet Mask, the IP Gateway and the Port for TCP/IP and UDP connec-
tions can be configured using the front panel menu or remote access.
Within the TCP/IP packets commands according to the multipoint syntax and command structure can be used
for remote monitoring and control. The device address used within that command structure needs to match
the internally configured multipoint address of the unit. The default address is 'A'.

2.7.11 Reference Signal Input
At the “Ref. In”connector (BNC, 50 W, female) an external reference signal can be connected. The frequency
can be either 10 MHz or 5 MHz. See chapter 3.5.2.7 for configuration options and details about this input.
2.7.12 IF Input Connector
The IF input signal is connected to the “IF In”connector at the rear panel. The type of connector is BNC,
50 Ohm or SMA (720 MHz IF), 50 Ohm, female. With dual channel devices, two IF inputs are available.
2.7.13 Ground Terminal
The ground terminal is a blade type connector with the width 6.3 mm.
Important: For save operation, this ground terminal must be permanently connected to a grounding
point!

3 Front Panel Operation
3.1 Power Switch
With the power switch on the front panel the mains supply for the Upconverter can be switched on or off. The
switch is recessed to achieve protection against unintentional operation.
3.2 Indicators
There are 6 LED’s on the front panel to indicate the operating conditions:
LED Name
State
Description
TX On
Green
The signal path is enabled.
Orange
The signal path is commanded to be on, but is temporarily disabled by
a warning or alarm (e.g. warm up mute), and will automatically go to
enabled when the alarm or warning terminates
Off
The signal path is disabled.
Test Mode
Orange
A test mode is enabled.
Off
Normal operation.
Remote
Continousley
Green
Unit is in remote mode (only available if REMOTE/LOCAL feature is
enabled) or lot of remote access happens.
Green
Flashing
A remote user is active on the unit.
Off
No remote user is active.
Warnings
Orange
A warning condition is active.
Off
Normal operation.
Stored Alarms
Orange
Alarm conditions have been stored with a time stamp
Orange
Flashing
The alarm history storage is full; no further alarms can be stored.

Notes: The REMOTE/LOCAL feature can be enabled in the System CFG menu, see 3.5.3.11.
If Multipoint commands are received which do not match to the internal multipoint address or mul-
tipoint packet format these commands are not indicated by the remote LED.
3.3 Test Outputs
The two optional test outputs on the front panel allow monitoring of the RF output and (optional) the IF input
signal:
·Test 1: RF output monitor signal (standard)
·Test 2: IF input monitor signal (option)
All test outputs have an approx. 20 dB reduced power level compared to the main IF/RF signal on the rear
panel.

3.4 Display and Keypad
All converter functions can be accessed via the front panel display and keypad or via the M&C remote control
interfaces.
Figure 12: User Interface with display and keypad
The display has 40 columns, 2 rows. Within standard type units a LCD-Display with illumination, within high
performance type units a VFD display is used. In case of a VFD display and front panel inactivity a moving
cursor is activated in regular time intervals to achieve some protection of the display against burn in. The
keypad consists of 4 cursor keys and 4 function keys. The left, right, up or down arrow keys allows to navi-
gate through the menu tree or allow to change the parameters of menu items which were selected for editing.
If more than one menu items are shown in a main or upper menu, the selected item is indicated with an arrow
symbol left and right of the menu item. This selection can be done with the left and right arrow keys.
The “Enter” key opens the selected submenu, activates the selected menu point for editing or confirms a
parameter input or change of a parameter. After changing parameters in the edit mode the parameters are
activated only after confirming the selected values by pressing the “Enter” key. At the same time the edit
mode is left. The “Cancel” key leaves selected submenus and leaves an edit/change mode without making
changes. Pressing the “Cancel” key in the edit mode discards changes made to parameters in the edit mode
and leaves the edit mode. Pressing the “Cancel”key again while in the main menu rearranges the main menu
to it's initial alignment. If a menu item within a submenu allows the change of a parameter this menu item is
displayed with all capital letters. Pressing the “Enter” key activates the parameter for editing. This is indicated
with an arrow signal left and right of the parameter value. A cursor shows the position within an alphanumeri-
cal parameter which can be changed. The left and right arrow keys allow to move the cursor. The up and
down arrow keys allow to change the selected parameter or selected character within the allowed range.
With the “TX On” key and the “TX Off” key the transmit path can be enabled or disabled. It is possible to disa-
ble these keys to prevent unintentionally operation. This can be configured with the menu item "ON/OFF
KEYS” within the "SYSTEM CFG" menu, which can be set to "Enabled" (keys are operational) or "Disabled"
(keys are not operational).
3.5 Menu Structure
The menu is structured in a main menu and submenus. In the following the items of the main menu and the
submenus are described. Menu items with all capital letters allow changes of configurations. Menu items with
mainly small letters only allow monitoring of parameters.
3.5.1 LOCAL or REMOTE
The item “LOCAL" or “REMOTE" is only shown if the REMOTE/LOCAL feature is enabled, which can be
achieved through a menu point (see 3.5.3.11) with the SYSTEM CFG Menu. This feature allows compatibility
with other equipment, where configuration access is either exclusively possible locally or remotely. It may be
also useful to protect from unintended remote configuration (through the M&C interfaces) if the unit is in local
mode, or from unintended configuration from the front panel, if the unit is in remote mode. If the unit is in local
mode, and if multipoint configuration commands are received through the M&C interfaces, the error response
"local mode" is sent back, and the commands are ignored. Status request commands are still possible. If the
unit is in remote mode, the configuration menus "CONV CFG" and "SYSTEM CFG" are not shown in the
main menu, access to configuration menu points is not possible, also the "TX On" and "TX Off" keys are ig-
nored.
