Brandywine - QFS-106 6 Output Free-Running Frequency Standard
- High stability OCXO or rubidium oscillator
- 6 individually buffered outputs
- Low phase noise output buffers
The QFS-106 is a high performance frequency standard. The unit provides 6 output channels of a single reference frequency, typically 10 MHz.
The internal reference oscillator options available are: free running OCXO or free running rubidium oscillator.
The QFS-106 has 6 individually buffered low phase noise outputs.
Each output has a level detector that will indicate loss of an output or overload via the front panel LED.
Power supply options include 115/230 VAC, 36 – 72 VDC, 18 – 36 VDC, or 09 – 18 VDC.
The QFS-106 is configured as a 1U 19” rack mount unit.
