4059B
1x15 LF (IRIG) Distribution Amplifier.
The 4059B is a one-input, fifteen-output Low Frequency amplifier in a 1U, 19 inch rack mount chassis. It provides fifteen isolated (> 70 dB) outputs from a single input. This unit is ideal for distributing IRIG A/B or G. An Ethernet port on the rear panel provides the capability to remotely monitor the status of the input and all output signals.
The 4036B is a 1-input, 15-output RF distribution amplifier in a 1U chassis. It provides fifteen isolated copies of a single input. The unit operates over a frequency range of 1MHz to 20 MHz. Fault sensing of signal level is provided on the input and every output. Faults are indicated on front panel LEDs as well as via an Ethernet interface.

4033A
1x15 5 Volt Pulse Distribution Amplifier.
The 4033A 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.

6502B
10 Channel RF Distribution Module.
Ten channel, RF distribution amplifier packaged in a 1U rack mount chassis. It is comprised of ten low phase noise RF amplifiers that maintain high channel isolation (>100dB). Up to ten units can be daisy chained together to give up to 100 outputs or each output of one unit can be used as a source for other 6502B units to give almost infinite expansion capability with virtually no signal degradation.

4037A
1x16 L1/L2 RF Distribution Amplifier.
The 4037A is a one-input, sixteen-output L1/L2-Band amplifier in a 1U, 19 inch rack mount chassis. It provides sixteen isolated (> 15 dB) outputs from a single input. This unit is ideal for distributing GPS antenna signals. The front panel provides green LED status for the power and antenna bias voltage setting.

9611B
Switch and Distribution Unit.
The 9611B switch and distribution system is an intelligent switching, monitoring and distribution system, packaged in a 1U rack-mount chassis.
The 9611B can be set up to distribute a wide range of signal formats; low noise sine waves, IRIG timecodes or pulse formats from either one of two inputs to all twelve outputs. The 9611B allows the user to deploy one model type to support multiple signaling formats which lowers support and logistics costs.
The 9611B provides for both manual and auto-switching signal distribution. When in auto-switching mode, the 9611 will detect any input or output failure based on the signal type being propagated. In the Auto mode, any input failure causes the unit to switch from Primary to Secondary source. Alarms will be indicated by all user interfaces including the front panel and Command Line Interface.
