LNDA-5, 10, 100
The LNDA-5, LNDA-10 and LNDA-100 are High Performance Distribution and Isolation Amplifiers designed to distribute signals from state-of-the-art atomic frequency standards. They offer exceptionally low additive phase noise and are designed for operation at 5, 10 and 100 MHz. The input signal is buffered and distributed to twelve 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. These amplifiers are available in a 1U, 19-inch rackmount enclosure with dual AC power for redundancy.
