HIGH PERFORMANCE DISTRIBUTION AMPLIFIER WITH ETHERNET, 1-100 MHz
The HPDA-15RMe 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 is engineered to distribute signals in the frequency range of 1 to 100 MHz. The input signal is buffered and distributed to fifteen isolated outputs. The instrument monitors the signal power levels. Faults are visible on the front panel LEDs and reported through the ethernet interface. The ethernet interface allows remote monitoring and control of the instrument. The HPDA-15RMe is available in a 1U, 19-inch rackmount enclosure, and the instrument runs on AC or DC power.
