The HPDA-15RM-C is a high performance distribution and isolation amplifier. The
standard unit contains three HPDA-5 modules. Each module provides five unity gain
outputs for every input signal. The HPDA-15RM-C may be modified upon request to
contain only two HPDA-5 modules.
The following specifications are valid for any HPDA-15RM-C that provides five unity gain
outputs for every input signal. Typical cross-channel isolation is 125 dB and reverse
isolation is typically greater than 135 dB. The phase noise of the modules is
exceptionally low, typically –150 dBc/Hz @ Fourier frequency of 1 Hz and –172 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.

Safety and Preparation for Use
SDI
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-15RM-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.
