AR-ONE C - FREQUENCY + PHASE COHERENT VERSION

For multi-receiver configurations (such as for direction finding purposes), in addition of frequency matching, PHASE MATCHING between receivers is also critical.
Whereas the AR-ONE already offers an ultra-stable reference frequency oscillator of 0.1ppm, the new AR-ONE C provides LOCAL OSCILLATOR SEPARATION, for best possible PHASE MATCHING between receiving units.

In addition of 10MHz frequency standard input/output connectors (for coherent), there are also 1st, 2nd, 3rd local oscillator input/outputs, for phase matching with a maximum 5% shift. The daisy chained receivers become therefore perfect clones in frequency and phase. The number of receivers which can therefore be interconnected, is only limited by the (non supplied) IF amplifiers and splitters used.. see the connection picture below.

SMA connectors for INPUT

SMA connectors for OUTPUT

10MHz standard oscillator

1^st& 2^nd local oscillators: 254.5MHz or 744.5MHz

3^rd local oscillator: 10.245MHz

IF (10.7MHz or 455kHz)

10MHz standard oscillator

1^st & 2^nd local oscillators: 254.5MHz or 744.5MHz

3^rd local oscillator: 10.245MHz

When the supplied bridge cables connect the above described In and Outputs, the AR-ONE C functions as a standard stand-alone AR-ONE. The only difference being that the IF OUT connector is of BNC type for AR-ONE, and SMA for AR-ONE C. Receiver specifications remain the same.

The following plot shows 2 interconnected AR-ONE C receivers having an identical phase for their respective IF OUT signals at 455kHz.
