Overview
The Brandywine Communications QFS-106 is a high performance reference
frequency standard distribution amplifier. The QFS-106 has two internal
reference oscillator options. The QFS-106 may use either a free running Oven
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. When more outputs are required, multiple
QFS-106 units may be daisy-chained to a single reference.

Unpacking and Installation
3.1
Unpacking
Carefully remove the QFS-106 from the shipping carton. The following items
should be included in the shipment:
• 1 QFS-106
• 1 user guide
• 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. Reverse the fuse holder and re-insert the fuse holder, making
sure that the correct AC or DC voltage is now displayed on the rear panel of the
QFS-106.
Use the supplied power mating connector for the QFS-106 unit (DC voltage
only). The user must connect the wires to the connector as shown in the table
below.

Installation
The QFS-106 may be bolted directly onto a 19” rack mount enclosure.
3.3
Connections
Connect the power source to the QFS-106. Now connect the input reference
signal and output reference signals to the appropriate connectors on the rear
panel of the QFS-106. The Reference Output connector may be used when
daisy-chaining multiple QFS-106 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
4.1
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 – 6) on the front panel of the unit will illuminate green.
Please note that units fitted with the quartz oscillators will take approximately five
minutes to warm up and these units will reach full accuracy after twenty-four
hours. Units fitted with the rubidium oscillators will take approximately ten
minutes to warm up.
4.2
Loss of Input Signal
The PLL LED illuminates green when an input signal is present on the Reference
Input connector on the rear panel of the unit. If the reference input fails, the front
panel PLL LED will extinguish.
4.3
Loss of Output Signal
The Output Monitor LEDs (1 – 6) illuminate green when output signals are
present on the Outputs connectors on the rear panel of the unit. If one or more
outputs fail, the front panel Output Monitor LEDs (1 – 6) will extinguish.
Please note that a short circuit on the output cable may not always trigger the
output alarm.

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. The front panel mounted potentiometer is used to adjust
the frequency of the QFS-106 unit. The table below describes this calibration.
