The FS100-RM is an ultra-low noise multiplying frequency synthesizer. The standard
FS100-RM unit multiplies a frequency input of 5 MHz or 10 MHz +13 dBm to provide
100 MHz output. The input frequency must be specified when placing the order.
The FS100-RM unit may be modified upon request to provide additional outputs at
10 MHz, 20 MHz, 40 MHz, 80 MHz, and 90 MHz.
The nominal output level of all output frequencies is +13 ±1 dBm. All outputs are
bandpass filtered to provide better than 50 dB of rejection for all spurious and harmonic
signals. The ultra-low residual phase noise of the multiplier allows it to be used with
state-of-the-art crystal frequency sources without degrading phase noise or
environmental stability.

CAUTION!
Voltages capable of causing injury or death are present in this instrument. Use extreme
caution whenever the instrument cover is removed.
Line Voltage
This instrument may be setup to operate on 100-120 or 220-240 VAC and a line
frequency of 50 to 60 Hz. The setup voltage for this FS100-RM is specified on
page 4.
Fuse
A 0.50 Ampere 250V slow-blow fuse is used for 100-120 VAC operation.
A 0.25 Ampere 250V slow-blow fuse is used for 220-240 VAC operation.
Only replace fuses with the same type and specifications.
Line Cord
The instrument has a detachable, three wire power cord for connection to a grounded
power source. The enclosure of the unit is directly connected to the outlet ground to
protect against electrical shock. Always use an outlet with a protective ground and do
not disable this safety mechanism.
Service
Do not attempt to service or adjust the instrument unless another person, capable of
providing first aid or resuscitation, is present. Contact SDI for any questions or repairs.

AC Power LED
The AC POWER LED will turn on when AC power is applied to unit and the unit is
operating properly.
DC Power LED
If the FS100-RM was manufactured with the battery backup option the DC POWER
LED should be on when DC power is applied and the unit is operating properly. If the
FS100-RM is not equipped with the battery backup option, the DC POWER LED will not
be connected but will still be on the front panel.
SMA INPUT
The 5 MHz or 10 MHz +13 dBm signal to be multiplied should be connected to the SMA
connector labeled INPUT.
SMA OUTPUTS
The standard FS100-RM has one 100 MHz output. The additional outputs at 10 MHz,
20 MHz, 40 MHz, 80 MHz and 90 MHz are optional. All the outputs have a nominal
output level of +13 ±1 dBm.

Description
If you acquired the optional battery backup module for your FS100-RM you will be able
to power your instrument with an external +24 VDC power source. In case of loss of the
main AC power this module will automatically power the unit. The switch from AC to DC
supply operation is affected by a Schottky diode network and charge storage capacitors
to ensure glitch free operation. The +24 VDC power source connector is located on the
back panel of the instrument. The +24 VDC ground is not connected to the instrument
case ground internally, however both ground connections are available at the DC power
connector and may be connected together at this point.
DC Voltage
The +24 VDC may be used as backup power to prevent loss of signal during power
outages. The DC power supply should be able to provide +24 VDC at 2A. For
optimum performance the following specifications should be used for the power supply.
DC Supply +24 VDC, 2 A
Line regulation +/- 0.05% for a 10% line change
Load regulation +/- 0.05% for a 50% load change
Output ripple < 5mV peak-to-peak
DC Fuse 2.0 Ampere 250V slow-blow
Fuse
A 2.0 Ampere 250V slow-blow fuse is used for +24 VDC operation.
Replace fuses with the same type and specifications
Service
Do not attempt to service or adjust the instrument unless another person, capable of
providing first aid or resuscitation, is present. Contact SDI for any questions or repairs.
Operation
To operate the unit on DC power, locate the DC power entry connector on the rear
panel and connect the power cable. When DC power is applied to the unit, the LED
located on the front panel labeled DC POWER should light up. Connection of the
+24 VDC supply is optional.

WARNING!
DO NOT APPLY AC VOLTAGE TO THIS UNIT THROUGH THE 6 PIN CONNECTOR
ON THE REAR OF THE UNIT!
Failure to follow these directions will cause injury or death to personnel, cause
irreparable damage to the instrument and void all warranties.
WARNING!
DO NOT REVERSE THE POLARITY OF THE SUPPLY VOLTAGE!
Reversing the polarity of the power supply will cause damage to the unit and void
all warranties.
WARNING!
The chassis of the instrument is internally connected to DC ground.
The +24 VDC connector is wired as follows:
Pin 1 NC
Pin 2 NC
Pin 3 NC
Pin 4 +24 VDC GND return
Pin 5 +24 VDC power
Pin 6 Chassis GND / Earth GND

This unit is designed to operate only with the specified voltage on page 4. For
conversion to a different voltage of operation contact SDI.
To operate the unit, locate the power entry module on the rear of the enclosure and
connect the power cord. Plug the unit into an appropriate power outlet. A LED on the
front panel labeled AC POWER will turn on. The 5 MHz or 10 MHz input signal to be
multiplied should be connected to the SMA connector on the front panel labeled INPUT.
The multiplied signals will be available at the second set of SMA connectors labeled
OUTPUTS. The input signal level must be greater than +12 dBm, otherwise the
synthesizer will not function properly and noise performance will be seriously degraded.
The multiplying synthesizer is not a linear device therefore the output power does
not vary linearly with input power. The absolute maximum specifications should be
observed to obtain the optimum performance and ensure reliability.
Absolute Maximum Ratings
Input RF Power +20 dBm Maximum
Reverse RF Power +20 dBm Maximum
DC Voltage @ Input 20 VDC Maximum
DC Current @ Input 100 mA Maximum
DC Voltage @ Output 50 VDC Maximum
Storage Temperature -10 to +75 ºC
Operation Environment 0 to +50 ºC
