DESCRIPTION

The HPDA-15RMi is an improved version of the High Performance Distribution and Isolation Amplifier with

performance exceeding that required to distribute state-of-the-art atomic frequency standards. This new model

offers the same exceptional low phase noise with a larger frequency bandwidth, greater isolation and

improved stability. The inputs and outputs have a low VSWR to minimize environmental effects on frequency

distribution through long transmission lines.

The HPDA-15RMi may contain up to three HPDA modules with each module providing five isolated outputs.

Each module contains an output level monitor LED located on the front panel. All the outputs power levels are

monitored and compared to a preset threshold of +7dBm. If the signal level on any output drops below this

threshold, the monitor LED for that module will turn off indicating a fault condition. The HPDA-15RMi also has

an open collector alarm signal that is available through the DC connector on the back panel. A fault on any

module may be used to activate the alarm signal. The instrument operates from both AC power and DC power.

The switch from the AC to the DC power supply is automatic and glitch free ensuring uninterrupted continuous

operation. The HPDA-15RMi comes in a 1U high, 19” rack-mount enclosure. The power requirements for this

model are 100-240 VAC and 9-36 VDC.
