The HPDA-15RMi-CW is a High Performance Distribution and Isolation Amplifier designed
to distribute state-of-the-art atomic frequency standards. This wide range model with a
frequency bandwidth of 1 to 100 MHz offers low additive phase noise, making it ideal for
use without concern in time scale applications where phase stability is of paramount
importance.
The amplifier is designed for maximum flexibility in system configuration in a 19 inch
rackmount, 1U enclosure, and may contain up to three RF signal distribution modules.
Each module takes a signal from 1 to 100 MHz and provides five buffered and isolated
outputs. All the output power levels are monitored and compared to a preset threshold If
the signal level on any output drops below this threshold, the monitor LED for the
corresponding module will turn off indicating a fault condition.
The HPDA-15RMi-CW is designed to be powered by a 100 to 240 VAC mains source
and/or by a +12 to +36 VDC power source. The DC power may be used as a main power
source for the instrument or in conjunction with the AC power as a backup power supply
in case of loss of the main AC power. The instrument is designed to automatically switch
from AC to DC supply operation using a Schottky diode network and charge storage
capacitors to avoid any glitches and ensure uninterrupted continuous operation.
