Page 5: Overview
Controlled Crystal Oscillator (OCXO) or a free running Rubidium Oscillator. Also, the QFS-106 has various power supply options. The QFS-106 may use either AC or DC input power supplies. The QFS-106 provides six output channels of a single reference frequency, typically 10 MHz. The QFS-106 has six individually buffered low phase noise outputs. -

• 1 power cord • 1 power mating connector (DC voltage only) Note the power connection on the rear of the QFS-106 chassis. Please take note of the voltage displayed near this power connection. If the AC or DC voltage setting is incorrect, use a small screw driver to remove the fuse holder. - Page 9 Units Figure 1 Daisy-Chain Interconnection When daisy-chaining multiple QFS-106 units, these units should be connected as shown in Figure 1. This configuration ensures that all outputs are accurately locked to a common reference with minimal injection of the phase lock loop noise.

Operation Powering the QFS-106 Once all the connections to the QFS-106 have been made, apply power to the unit by switching the power switch to the on position. The power switch is located on the rear panel of the unit. The Power LED and Output Monitor LEDs (1 –... -
Page 11: Calibration
Calibration The QFS-106 is a free running standard that requires periodic recalibration. The unit must be calibrated against a frequency standard that is at least ten times more accurate than the oscillator fitted in the QFS-106 unit. Therefore OCXO oscillator units must be calibrated against a rubidium reference. Rubidium oscillator units must be calibrated against a cesium frequency standard or GPS disciplined rubidium. -
