Introduction

1.0 Description
This manual discusses the Radyne SFC1800A Synthesized Frequency Upconverter (Figure 1-1).
This high-qu al ity, rack-mountable sa tellit e upco nverter is intended for use in medi um-to-large
earth station installations where multiple carrier uplinks need to be established . The SFC1800A
Upconverter is ready to be configured into a variety of backup switch configurations, which
include 1:1, and 1:N (where N is a maximum 8) configurations.
Figure 1-1. SFC1800A Upconverter Front Panel
The SFC1800A Upconverter is a DBS-Band, 125 kHz reso lution synthesi zed satellite upconverter
capable of converting either a 3 6 MHz bandwidth, 70 MHz IF inpu t or optionally a 72 MHz
ban dwidth, 140 MHz input to a DBS-Band uplink i n the range of 17.30 - 18.40 GHz.
All of the configu r ation, monitor, an d contr ol functions are available at the front panel. Operat ing
parameters such as frequency, channel, gain, gain offset, and switch settings (backup only) can
be readily set and changed at the front panel. Additionally, all functions can be accessed with a
terminal or personal com puter via a serial li nk (RS-232, RS-485, or Ethernet) for complete remote
monitoring and control ( M &C) capabili ty. Extensive fault monitoring wit h masking capability,
along with time and date stamped event st or age is ava i lable.
The units m onitor l ocal oscillato r ( LO) phase-locked loop faults in the converter at all times dur i ng
operat ion. If a fault i s detected, the converter immediately g oes int o the S tandb y Mode. If
multiple converters are configured t o provide backup protection switching, a summar y fau lt will
sig nal the backup, which will put itself online and r estore the failed circu it.
The RF Hardwar e consists of a broadb and synthesizer, a fi xed freq uency phase l ocked oscillator,
and the first and se cond converter modules. The broadband syn thesizer provides the
synt hesized local oscillator for the conversi on from L-Ban d to RF output. The LO that tunes from
14.80 - 15.9 0 GHz performs this conversion. The second mi xer co nvert s the 70 or 140 MHz IF
input to L-Band. A fixed frequency First IFLO performs this frequency conversion.
A 20 dB gain co ntrol attenu ator at t he L-Band of the second m i x module controls the power out of
the converter. This attenuator is capable of 0. 1 dB reso lution through a software li near
interpolat ion of 1 dB cal i bration values.

Introduction SFC1800A Synthesized Frequency Upconverter
The SFC1800A Upconverter have been designed to provide performance that meets or exceeds
all in dustry standards i n effect today for satell i te com muni cation s earth stati on frequency
converter eq uipment fou nd worldwide. In addition to providing robust performance , th e
SFC1800A Upconverter are loaded with feat ures t hat will provide ease of integration and
operation.
1.1 Protection Switch Versatility
Radyne SFC converters featur e ‘plu g-and-play’ ease of installation wit h th e RCU101 1:1 or th e
RCU1 08 1:8 Redundancy Control Units. All convert er s can be plugged in to the b ackup slot and
assume the r ol e of protection switch con troller. The backup converter l earns and stores the
frequ ency, gain and channel settings of the p r imary conver ters. The backup converter can be
operat ed automatically, in which case an automatic backu p of a fault ed, online C onverter occurs
after a user-programmed delay. The Backup may also be operated manually, all owing the user
to m anually switch i n the B ack up Uni t. The Fron t Panel controls and indica tors p r ovide for
automatic/man ual configurat ion, as well as display of onlin e/offline status information. In the
event the stored settings of the Prim ar y Converter are changed, th e backup co nverter will not i fy
the user.
All circu i ts are p r otected upon installation of the swit ch an d completion of the lear ning process.
This eli min ates the need for complicated soft ware configurations that m i ght oth er wise lea ve a
circuit vu l nerabl e. Likewise, rep l acing a failed converter is as sim ple as plugging in a
replacement.
1.2 Chain Switching (Optional)
Chain Switching is availab l e as an op tion for the SFC1800A Upconverter. This unit can be
delivered with t he optional Chai n Switching Module in place, or may be purchased separ ately and
installed by the customer (no tools are required). When equipped with thi s module, in the event
of a unit failure (in a 1:1 or 1:N Configuration where N is less than or eq ual to 8), the upconverters
themselves perform the switching. This elimi nates the need for a separate converter protection
switch such as the Radyne RCU101 or RCU108.

2.0 Installation Requirements
The SFC1800A Upconverter is desig ned to be installed within any standard 19 inch eq uipm ent
cabi net or rack, an d requi r es 1 Rack Unit (1RU) mounting space (1.75 inches, 4.44 cm) vertically
and 19 inches (48.26 cm) of depth. Including cabling, a minimum of 20 i nches (50.8 cm ) of rack
dep th is required. The rear panel is has power enter from the left and cab ling en ter from the
center and right as viewed from the rear of the unit. Dat a and con trol cabling can enter from
either side. The unit can be placed on a table or suit able st able surface if requir ed.
Before initially applying power to the unit, it is a good idea to disconnect
the transmit output from the operating station equipment. This is
especially true if the current SFC1800A Upconverter configuration
settings are unknown, where incorrect setting could disrupt existing
comm u nica tions traffi c.
There are no user-serviceable parts or configuration settings located
inside the SFC1800A Upconverter chassis. There is a potential shock
hazard internally at the power supply module. DO NOT open the SFC
Chassis under any circumstances.
The SFC1800A Upconverter contains a Lithium Battery. DANGER OF
EXPLOSION exists if the battery is incorrectly replaced. Replace only
with the same or equivalent type recommended by the manufacturer.
Dispose of used batteries in accordance with local and national
regulations.

Turn the unit ‘ON’ by pl acing th e r ear panel swi tch ( above the power entry connector) to t he ‘ON ’
position. Upon initial and subsequent power-ups, the SFC1800A Upconverter w i ll test itsel f and
several of its components before beginning i ts main Monitor & Control Program. The Event
Buffer LED will illuminate and the unit will log setup events upon power-up. This allows the user
to tel l if there was an accidental power failure or i f the power was manually cycled for any reason
while the unit was left unattended. These events can be cleared after setup. If any failure is
detected, an Alarm LED will illuminate.

Theory of Operation SFC1800A Synthesized Frequency Upconverter
3.1 Converter Configuration
The SFC1800A Upconverter has three basic operating configurations. These are: S tand-Alone,
1:1 Sw it ch, and 1:8 S witch.
The upconverter automatically detect s the equipm ent to which it is conn ected, and adjusts its
operat ion accor dingly. S ome user menus, most notably the switch Men u, are only avail able if the
up converter i s connected as the backup unit in a Redundancy Switch System.
The Switch Systems may be referred to as either a Redundancy Switch, a
Protection Switch, or simply a Switch. In addition, in all switch
configurations, the Backup Unit acts as the master (it controls all switch
operations).
3.1.1 Stand-Alon e Opera t io n
If J5 on the Back Pan el of the SFC1800A Upcon vert er (B.U. SWI TCH INTERFACE) is n ot
connected to a Switch, th e unit will automatically configu r e i tself for Stan d-Alone Operati on. The
user can set up all configurabl e param eters using one of t he four differen t In terfaces described in
Section 4.
3.1.2 1:1 Switch
In the case of a 1 :1 Switch System, the upconverter detects to which connector on the switch it is
connected (INTERFACE BACKUP or INTERFACE PRIMARY).
The Primary is also sometimes referred to as the Prime.
If the upconverter is conn ected as the backup, then al l the switch con trols are available to t he
user on that unit.
Figure 3-2 illustrates a typical interconn ection of a SFC1800A Upconverter with an RCU101 1:1
Prot ection Switch.
3-2 TM111 - Rev. 1.0
SFC1800A Synthesized Frequency Upconverter Theory of Operation
3.1.3 1:8 Switch
In a 1:8 Switch, the Converter detects whet her it is con nected as PRIM ARY1 through
PRI M ARY8, or as the BACKUP. The RCU108 is flexible in that it can be set up with anywhere
from 1 through 8 Pri mary SFC 1800A Upconverters. H ow ever, there is only on e backup. Thus,
only one Prime can be backed up at one time.
Figure 3-3 illustrates a typical interconn ection of a SFC1800A Upconverter with an RCU108 1:8
Protection Switch. The configuration shown is a 1:2 Switch.
3.2 Optional Chain Switching Operation
For Ch ain Swit ching, each convert er in a 1:N configurat i on (where N is less than or equal to 8)
will co ntain an op tional C hain Switching Module. Duri ng set up, one of the con verters will be
considered the backup. This is u sually th e converter at t he bot tom of th e r ack. Once the system
is set up and proper l y wi r ed, each con verter t hen has an ID Address and can be programmed
from t he Fron t Panel to set the priority level of each converter in the rack. If no priority is set from
the Front Panel then th e priority will default to level one with the converter cl osest to the back up
having the highest prior i ty and priorities incrementall y decreased the furt her from the back up.

TM111 – Rev. 1.0 3-3
Theory of Operation SFC1800A Synthesized Frequency Upconverter
After al l of the converters have been programmed, th e back up co nverter is then set into a “Learn
Mode. ” The backup poles each converter on a continuous basis, and learns then stores the
setting s of each con verter. Because the swi tch m odules are on a common pr otection bus, each
converter knows the address (position in th e r ack), and the faul t status of all of the converter s in
the r ack. In the event of multiple fail ures, the highest priorit y co nvert er that fails is backed up fir st.
The chain switch provides the primary through path between the converter RF output and the
output of the switch module without bei ng powered . It i s provided with redundant power from all
converters co nnected in the chai n. In the event that a Upconvert er needs to be replaced, th e
Chain Switching Module ca n be removed from the back of t he converter and left in place with out
breaking the interconnecti ons to adj acent converters in t he ch ai n.
Refer to Figure 3-4 for Chain Switching Operation in a 1:1 configuration, and Figure 3-5 for a 1:N
configuration.

4.2.3 Switch Menu Options and Parameters
This Menu is only available when the upconverter is conn ected i n a 1:1 or 1:N Switch
configuration as the Backup Unit.
BACKUP MODE: {MANUAL, AUTO-NONREVE, AUTO-REVERTI}
Sets the Backup Mode of the swi tch.
Manual: A Prime Con verter can be backed up t hrough
manual control onl y.
Auto-Nonrevertive: A Prime C onverter will be backed
up if it fails. It will remain backed up until it is manually
unbacked.
Auto-Revertive: A P r i me Con verter will be backed up i f
it fails. If a second Converter, which has been deemed
higher prior i ty (see Monitor Backup S tate below) fails,
the switch will unback the first and backup the second
Converter. If the first Con verter recovers after it has
been backed up (i.e., no l onger has a fault) , and a
second Con verter fails, the recovered unit will be put
back on line and the new faulted unit will be backed up.
FORCE BACKUP <SELECT PRIME >: {PRIME 1 - 8, UNBACK}
When i n Manual Backup Mode, this selection will force
the selected Prime to be backed up. Unback will release
any Prime that is currently backed up.

PRIME SETUP:
PRIME #:
PRIORITY: {0 - 8}
Sets the switching priority of a Prime Un it. If more than
one u nit fail s at the same ti me, the higher priorit y unit will
be backed up. Also, if one unit is currently backed up
and a second unit with a higher priority fails, the first unit
will be unbacked and the second unit will be backed up
(but only if Backup Mode is Auto-Revertive, see Backup
Mode above). The priority is se t as fol l ows:
0 = No p r iority (the switch will ignore the upconverter). If
at any time a Prime’ s priority is set t o 0, t he
Backup will p urge any learned parameters of
that Prime.
1 = Highest priority.
8 = Lowest prior i ty.
COMPENSATION: {- 5.0 - +5.0}
Offsets the gain of the Backup Uni t to account for
variations in loss through the system. This allows the
user to ensure that the signal path of a particu lar Prime
Converter maintain s the same outp ut power wh en
backed up.
MONITOR:
BACKUP STAT E: {NONE, PRIME1 - 8}
Reports the current Backup Stat e of the swit ch. If no
