  • Page 2 HPDA-100RM-C Description The HPDA-100RM-C is a high performance distribution and isolation amplifier. It contains 2 modules that provides ten 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...
  • Page 3: Safety And Preparation For Use

    To operate the unit, locate the AC power entry connector on the rear panel and connect the power cable. When power is applied to the unit, a red led located on the front panel, labeled “on”, should light up. Copyright © SpectraDynamics, Inc. 2005...

    The Back Panel The Back Panel AC POWER ENTRY MODULE The HPDA-100RM-C is configured to operate on 100 to 120 VAC. DC POWER ENTRY CONNECTOR Optional Battery Backup Connector for +24 VDC Backup power source SMA INPUTS There is one SMA input. The signal to be distributed should be connected to the SMA jack labeled input.
  • Page 6: Battery Backup Module

    Battery Backup Module 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 effected by a schottky diode network and charge storage capacitors to ensure glitch free operation.
