The HPDA-100RM-C is a high performance distribution and isolation amplifier. The
standard unit contains three HPDA-100 modules. Each module provides five unity gain
outputs for every input signal. The HPDA-100RM-C may be modified upon request to
contain only two HPDA-100 modules.
The following specifications are valid for any HPDA-100RM-C that provides five unity
gain outputs for every input signal. Typical cross channel isolation and reverse isolation
is generally greater than 100 dB. The phase noise of the modules is exceptionally low,
typically –145 dBc/Hz @ Fourier frequency of 1 Hz and –174 dBc/Hz @ Fourier
frequency greater than 10 kHz. Both the input and output are matched to 50 ohms to
obtain better than 20 dB return loss.

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 HPDA-100RM-C 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
The DC POWER LED is on when DC power is applied to unit and the unit is operating
properly.
Monitor LED
The MONITOR LED of each module will turn on if all the output signals to the
corresponding module are greater than +7 dBm.

AC POWER ENTRY MODULE
The HPDA-100RM-C is configured to operate on:
100-120 VAC
220-240 VAC
DC POWER ENTRY MODULE
Optional Battery Backup Connector for +24 VDC Backup power source.
SMA INPUTS
The standard HPDA-100RM-C contains three amplifier modules each having one input
SMA connector. If you acquired a modified unit with only two HPDA modules the back
panel will contain only two SMA input connectors. The signal to be distributed should be
connected to the corresponding SMA jack labeled INPUT.
SMA OUTPUTS
There are five SMA OUTPUTS for each SMA INPUT. Any output may be used to drive
the input of another distribution module. The five outputs of each amplifier module are
DC isolated from the chassis ground to prevent ground loops. Make sure that the
amplifier ground does not float to a potential greater than 50 VDC from the chassis
ground. An output ground potential greater than 50 VDC will damage the amplifier and
could cause injury or death to personnel.

Description
The battery backup module allows the HPDA-100RM-C instrument to be powered by a
+24 VDC power source in case of loss of the main AC power. 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 AC voltage on page 4
and +24 VDC. For conversion to a different voltage of operation contact
SpectraDynamics, Inc.
To operate the unit, locate the AC power entry module on the rear of the enclosure
and/or the DC connector and connect the power cord(s). Plug the unit into an
appropriate power outlet. The LED on the front panel labeled AC POWER will turn on
when you apply the AC voltage. If you also apply the DC voltage the LED labeled DC
POWER on the front panel should light up. Attach the signal to be distributed to one of
the SMA input connectors on the back panel. Any HPDA-100RM-C output may be used
to drive the input of another distribution module.
