  • Page 3: Summary

    6/01/17 DATE 1.0 Summary The ND0115 is a 15/16 channel wide bandwidth distribution amplifier. While primarily used for 10 MHz reference distribution, it has a functional bandwidth from DC to 12 MHz, but is filtered for the lowest phase noise 10MHz signal.
  • Page 4 ND0115 USERS MANUAL REVISION NO. 6/01/17 DATE The amplifier can also be optionally redundant. The redundancy feature adds a second power supply and a second 15/16 channel amplifier PCB assembly. The dual input design monitors the input signals and selects the active signal or the prioritized signal.

  • Page 5: Controls And Indicators - Front Panel

    ND0115 USERS MANUAL REVISION NO. 6/01/17 DATE 2.0 Controls and Indicators – Front Panel This section describes the functionality of the front panel controls and indicators.

  • Page 6: Channel Status

    ND0115 USERS MANUAL REVISION NO. 6/01/17 DATE 2.1 Channel Status The Channel Status can be determined by reading the actual RMS value on the output of each stage. This is compared to a threshold limit that is set by the user as a percentage variation from a saved value.

  • Page 7: Status Leds

    ND0115 USERS MANUAL REVISION NO. 6/01/17 DATE The current threshold limits are displayed in addition to the actual measured value. These values reflect the percentage threshold defined in the Alert Threshold settings. If the output value is too low to give a valid reading - the display will read “LOW.”...
