The RDA-6 is a six channel Reference Distribution Amplifier designed for distributing an external reference frequency standard, such as a Stanford Research PRS-10 Rubidium reference or a Trimble Thunderbolt GPS disciplined oscillator, to laboratory equipment such as frequency counters, spectrum analyzers or signal generators. This allows all of your laboratory equipment to be stabilized to one reference frequency.

The RDA-6 provides very high isolation between output channels and very high isolation between any output channel and the input channel This prevents one piece of test equipment from disturbing another piece of test equipment which is a typical problem using resistive power splitters to distribute a reference frequency.

The output level is typically +10dBm with a +10dBm input channel level. This meets the required driving level of most test equipment. Each output channel level can be adjusted over a 60dB range from +10 to -50dBm, allowing independent level settings for each channel if needed.

Each RDA-6 is powered from a wall mounted 24VDC power supply and the unit is always powered ON as there is no power switch to get turned off accidently. A rear mounted green LED indicates the power on condition of the RDA-6.

The RDA-6 is offered in two versions. The RDA-6 is a fully assembled unit in an enclosure as pictured, with BNC connectors and 24 Volt wall mount power supply included.

The RDA-6PCB is a fully assembled Printed Circuit Board with all (6) channels populated, but the enclosure, BNC connectors and 24 Volt power supply are not included. This allows the RDA-6PCB to be integrated into your own enclosure along with for example the Trimble Thunderbolt GPS Disciplined Oscillator. Here is a photo of the assembled PCB.
