The HPDA-15RM-B is a high performance distribution and isolation amplifier. It

contains three modules each of which provide five unity gain outputs for every input

signal.

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. Typical

cross-channel isolation is 125 dB and reverse isolation is typically greater than 135 dB.

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-15RM-B 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.

Safety and Preparation for Use

SDI

AC Power LED

The POWER LED is on when power is applied to unit and the unit is operating properly.

Monitor LED

The Monitor LED labeled 1 will be on if all outputs on the first HPDA module have

signal levels greater than +7 dBm. The Monitor LED labeled 2 will be on if all outputs

on the second HPDA module have signal levels greater than +7dBm. The Monitor LED

labeled 3 will be on if all outputs on the third HPDA module have signal levels greater

than +7dBm.

The Front Panel

SDI

AC POWER ENTRY MODULE

The HPDA-15RM-B is configured to operate on:

100-120 VAC

220-240 VAC

SMA INPUTS

The HPDA-15RM-B contains three amplifier modules each having one input SMA

connector. 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.

The Back Panel

SDI

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 AC power entry module on the rear and connect the

power cable. Plug the unit into an appropriate power outlet. A green LED on the front

panel labeled “POWER” will turn on. Attach the signal to be distributed to any of the

SMA input connectors on the back panel. Any HPDA-15RM-B output may be used to

drive the input of another distribution module.
