The HPDA-15RMi-CW is a High Performance Distribution and Isolation Amplifier designed to distribute state-of-the-art atomic frequency standards. This model offers exceptionally low additive phase noise and has a frequency bandwidth of 1 MHz to 100 MHz. This amplifier may be used 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 provides five isolated outputs. All the output power levels are monitored and compared to a preset threshold of 0 dBm. 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 or by a +12 to +36 VDC power source. The DC power module may be used as a main power source for the instrument or in conjunction with the AC power module 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.
