QFS-106 Quartz Frequency Standard The QFS-106 is a high performance frequency standard. The QFS-106 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. Features: High stability OCXO or rubidium oscillator 6 individually buffered outputs Low phase noise output buffers Related Brandywine Communications Products PTS: High performance GPS disciplined frequency standard with network interface. GPS8: Power supply options include 115/230 VAC, 36 – 72 VDC, 18 – 36 VDC, or 09 – 18 VDC. Stand alone GPS time and frequency system. The QFS-106 is configured as a 1U 19” rack mount unit. Distribution amplifier with up to 2 output frequencies, time code, and 1 PPS. It has a built in low noise OCXO for hitless switching.
