  • Page 5: Summary

    071221 Summary The ND2310D is a ten 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 at 10MHz. For applications other than 10 MHz the unit must be factory configured.
  • Page 6 USERS MANUAL ND2310D REVISION DATE 071221 The amplifier can also be optionally redundantly powered. The redundancy feature adds a second power supply which may be AC or DC. The dual input design monitors the input signals and selects the active signal or the prioritized signal.
