  • Phase stabilization for a frequency multiplier
    Patent number: 10680621
    Abstract: A frequency multiplier circuit includes a frequency multiplier, a phase detector and a control circuit. The phase detector detects a difference between an input phase of an input to the frequency multiplier and an output phase of an output from the frequency multiplier. The control circuit is configured to maintain the output phase based on the difference detected by the phase detector.

  • Instrumentation chassis with high speed bridge board
    Patent number: 10579574
    Abstract: An instrumentation chassis includes a backplane, multiple peripheral slots located on the backplane and configured to receive insertable peripheral modules, respectively, and at least one protocol agnostic high speed connection mounted on, but not electrically connected to the backplane. The high speed connection is configured to interconnect at least two peripheral modules in corresponding peripheral slots of the multiple peripheral slots, bypassing the backplane.
