  • Page 3 DATE 091420 1.0 Summary The ND2316D is a ten channel wide bandwidth distribution amplifier. While primarily used for 10 MHz reference distribution, it has a functional bandwidth from 100kHz to 12 MHz but is filtered for the lowest phase noise 10MHz signal.
  • Page 4 USERS MANUAL ND2316D REVISION DATE 091420 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.

  • Page 5: Controls And Indicators - Front Panel

    USERS MANUAL ND2316D REVISION DATE 091420 2.0 Controls and Indicators – Front Panel This section describes the functionality of the front panel controls and indicators. Two buttons above the status LEDs provide navigation through the menus. In general, the NEXT button advances through the menus to the next screen, while the SELECT button chooses between the available values on a menu.
  • Page 6 USERS MANUAL ND2316D REVISION DATE 091420 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. The default variation value is set at ±25% percent from the current state of the...

  • Page 7: Status Leds

    USERS MANUAL ND2316D REVISION DATE 091420 2.2 Status LEDs There are three status LEDs which provide a quick indication of valid unit operation. Alert LED: The alert LED will illuminate flashing red to indicate an input failure or a power supply failure. The alert LED will not flash red if any valid input signal is present.

  • Page 8: Power Supply Status

    USERS MANUAL ND2316D REVISION DATE 091420 2.4 Power Supply Status The power supply status screen provides DC voltage values of the two available power supply sources. The 90-250V AC input is internally connected to an internal 24V AC-DC convertor which powers the internal supplies with 24V.

  • Page 9: Alert Threshold

    USERS MANUAL ND2316D REVISION DATE 091420 2.9 Latch Channel Values The latch channel values screen allows the user to save the current channel output values for use as the reference value for alert settings. A channel alert is triggered when a channel output voltage exceeds or falls below a percentage of the reference value.

  • Page 16: Fault Status

    USERS MANUAL ND2316D REVISION DATE 091420 2.10 Fault Status The fault status screen allows a quick overview of any channel faults from the front panel. The total fault count is listed, as well as a visual flashing indication of any channels that are beyond the threshold values.

  • Page 17: Power Switch

    USERS MANUAL ND2316D REVISION DATE 091420 2.11 Power Switch The rear panel power switch controls AC power input to the unit. If the optional DC input is provided with 24V, or a valid DC supply, the unit will operate. If the unit is powered with the DC Option, the rear panel switch does not remove DC power.

  • Page 18: Rs232 Db9 Port

    USERS MANUAL ND2316D REVISION DATE 091420 2.12 RS232 DB9 Port The front panel RS232 port allows convenient setup of the unit in addition to the rear panel RS232 which may be connected to a more permanent instrumentation setup. The front panel RS232 port will respond to the same commands as the rear panel, and any changes made will be reported on both serial ports.

  • Page 19: Rear Panel

    USERS MANUAL ND2316D REVISION DATE 091420 3.0 Rear Panel 3.1 Channel Outputs - BNC There are ten outputs across the left hand side of the rear panel. They are labeled 1 through 10. Nominally the outputs are 50 Ohm impedance.

    USERS MANUAL ND2316D REVISION DATE 091420 4.1 Bandwidth 20 KHz to 10MHz. Gain flatness is ±2dB. The amplifier is available with output drive to DC. Though the unit operates well across wide bandwidth, filtering and design have been optimized to reduce phase noise at 10 MHz.

  • Page 24: Outputs

    USERS MANUAL ND2316D REVISION DATE 091420 4.3 Outputs Each output is fault and electrostatic discharge protected. Each output is independent, and any output can be faulted for an indefinite period of time with no permanent damage. Each output is connected to a monitor circuit that detects a local fault on the output.
