  • Page 3 USERS MANUAL ND2310D REVISION DATE 1/12/20 1.0 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 10MHz signal.
  • Page 4 USERS MANUAL ND2310D REVISION DATE 1/12/20 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 ND2310D REVISION DATE 1/12/20 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: Channel Status

    USERS MANUAL ND2310D REVISION DATE 1/12/20 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. The default variation value is set at ±25% percent from the current state of the amplifier and is user-programmable in 5% increments from ±10% to ±60%.

  • Page 7: Status Leds

    USERS MANUAL ND2310D REVISION DATE 1/12/20 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 ND2310D REVISION DATE 1/12/20 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 ND2310D REVISION DATE 1/12/20 Redundant power supplies operate on either the AC input or DC input, and function independently. All functionality and reporting for an individual power supply and amplifier is independent of its redundant copy. 2.6 Alert Threshold The alert threshold screen allows the user to adjust the tolerance from the reference voltage which, if exceeded in either direction, the output channels will report a fault status.
  • Page 10 USERS MANUAL ND2310D REVISION DATE 1/12/20 Each channel has a reference voltage which can be set, all at once, by latching the channel’s current value in the latch channel average screen. Each channel’s reference voltage can be set individually by writing the value serially with the $SET command.
  • Page 11 USERS MANUAL ND2310D REVISION DATE 1/12/20 The alert threshold can be optimized so that a channel short or an impedance change will cause an alert. Page #: 11 of 39 www.novuspower.com...
  • Page 12 USERS MANUAL ND2310D REVISION DATE 1/12/20 Example: The output of channel 1 is connected to a high impedance input and reports 1.25Vrms at the output. The output of channel 2 is connected to a 50 Ohm terminated input, and reports 0.90Vrms at the output. Input A is connected to a ~0.95V 10MHz source.

  • Page 13: Input Threshold

    USERS MANUAL ND2310D REVISION DATE 1/12/20 2.7 Input Threshold The input threshold screen allows the user to monitor and set the threshold at which the input is regarded as invalid or faulted. The input threshold value is the absolute voltage (user programmable between 0.1Vrms and 1Vrms) below which the input fault will occur, and the auto input select will consider the signal invalid.

  • Page 14: Input Select

    USERS MANUAL ND2310D REVISION DATE 1/12/20 2.8 Input Select The input select screen allows the user to monitor and select the input priority for inputs A and B. Pressing the SELECT button with advance through the following settings: Input A Select Input B Select Auto Select (Priority A) Auto Select (Priority B)

  • Page 15: Latch Channel Values

    USERS MANUAL ND2310D REVISION DATE 1/12/20 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 ND2310D REVISION DATE 1/12/20 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. Press SELECT to advance to the system fault screen.

  • Page 17: Power Switch

    USERS MANUAL ND2310D REVISION DATE 1/12/20 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 ND2310D REVISION DATE 1/12/20 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 ND2310D REVISION DATE 1/12/20 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. 3.2 Status LEDs There is an LED to the right of each BNC.

  • Page 20: Signal Input A/B

    USERS MANUAL ND2310D REVISION DATE 1/12/20 3.3 Signal Input A/B Signal input. Standard impedance is 50 ohms. Maximum signal input is 1.5 Vrms. By default, Auto(A) priority is selected, meaning Signal A is considered primary, and B is used if A is detected as being out of tolerance.

  • Page 21: Ac Input

    USERS MANUAL ND2310D REVISION DATE 1/12/20 3.5 AC Input The AC input accepts 90-250Vac, 50-60Hz. IEC 320-C14 Compliant. 3.6 RS232 DB-9 An RS232 port is provided for local setup, and status monitoring. The embedded processor provides status strings, as well as command responses.

    USERS MANUAL ND2310D REVISION DATE 1/12/20 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 ND2310D REVISION DATE 1/12/20 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.

  • Page 25: Programming Guide (Rs232 Port: Front And Rear)

    USERS MANUAL ND2310D REVISION DATE 1/12/20 Also, in most applications, the equipment that surrounds this unit is sensitive and the filter also reduces noise that could impact the performance of other equipment. If the optional DC Power Option is installed, the unit can be powered from nominal 24 Vdc.
  • Page 26 USERS MANUAL ND2310D REVISION DATE 1/12/20 The checksum can be required for all input commands, and the requirement for a checksum can be enabled or disabled (default setting is disabled).
