Front panel lights allow you to check status of the amplifier at a glance. Indicators are provided for power, alarm, input, and all 12 outputs. An alarm occurs whenever there is loss of input signal, or loss of any of the 12 outputs. Full remote control and monitoring of the amplifier can be done through the Ethernet port, including checking status and alarm conditions.

The oscillators are disciplined to either the input frequency or GPS. Using the oscillators in combination with external reference inputs provides various levels of redundancy. The oscillators also add holdover capability so that uninterrupted operation is maintained in the event of total failure of the reference input(s). Model 56000 outputs can include distributed or generated clock signals, frequencies, Network Time Protocol, and IRIG B time code. N.1 clock rate generation from 1Hz to 25MPPS in 1 PPS steps is available in addition to N.8 clock rate generation from 8 KPPS to 8.192 MPPS in 8KPPS steps. Also available is a Telecommunications Interface that provides a variety of outputs and alarms common in today’s telecommunications applications. The chassis is configured with front and rear plug-in cards. The front panel plug-in circuit cards perform the modular rate generation and distribution functions and are hot swappable. The rear panel interfaces are also implemented using plug-in cards with a wide variety of connector types and styles. Of the 21 card slots available, four are reserved for the power | |

The 4032A is a one-input, fifteen-output pulse distribution amplifier in a 1U,19-inch rack mount chassis. It provides fifteen isolated outputs from a single input. An Ethernet port on the rear panel provides the capability to remotely monitor the status of the input and all output signals. Any failure in the unit will immediately provide an alarm to the Ethernet port. The front panel provides green LED status for the input and green/red for all output signals, as well as indicating an input of 1 PPS, DC IRIG, or Other. The 4032A can be configured to custom requirements.
