The HPDA-100RM-A is a high performance distribution and isolation amplifier. It
contains one module that provides five unity gain outputs. Typical cross channel
isolation and reverse isolation is typically greater than 100 dB. The phase noise of the
modules is exceptionally low, typically –145 dBc/Hz @ Fourier frequency of 1 Hz and
–173 dBc/Hz @ Fourier frequency greater than 10 kHz. Both the input and output are
matched to 50 ohms to obtain better than 25 dB return loss. All outputs are AC coupled
and the grounds are DC isolated to reduce the effect of ground loops.

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-A is specified on
page 4.
Fuse
A 2.0 Ampere 250V slow-blow fuse is used for 100-120 VAC operation.
A 1.0 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 LED labeled POWER is on when power is applied to unit and the unit is operating
properly.
Signal LED
The LED labeled SIGNAL will turn on when you apply an input signal to the SMA input
connector greater than +7 dBm.

AC POWER ENTRY MODULE
The HPDA-100RM-A is configured to operate on:
100-120 VAC
220-240 VAC
SMA INPUT
The signal to be distributed should be connected to the SMA jack labeled INPUT.
SMA OUTPUTS
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.

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. The green LED
on the front panel labeled POWER will turn on. Attach the signal to be distributed to the
SMA input connector on the front panel. Any HPDA-100RM-A output may be used to
drive the input of another distribution module.
