High performance pulse and frequency distribution amplifier for time and
frequency metrology. The pulse distribution board is an 1:8-channel (1
Hz and up) logic-level distribution amplifier, while the frequency
distribution board is an 1:8-channel sine-wave (1-30 MHz) distribution
amplifier. Two 1:8 boards fit side-by-sides in a 1U 19" rack enclosure,
with either BNC or SMA connectors.
