It delivers instrument-grade performance, increased functionality, and efficient power consumption at a reduced size and affordable cost. The sleek design combines low phase noise with fast switching capability, covering a wide frequency range from 8 kHz up to 20 GHz. The low spurious and harmonic content of the signal makes it ideally suitable for many demanding applications. Optimal Substitute for National Instruments (NI) Models FSW-0020, FSW-0010, FSL-0010 and FSL-0020. Among the Model 805-SG’s notable features is its high stability OCXO, which provides accurate, power-calibrated and phase-lockable output signals. The frequency resolution is 1 mHz and the power resolution is 0.01 dB power. BNC offers the option for the module to support anolog modulations. The unit is remotely controlled with USB, LAN or SPI control. The 805-SG is a popular choice among RF and microwave engineers and scientists. It integrates excellent signal purity, accurate setting capabilities, and quick switching capabilities. As the industry strives for quality, the 805-SG leads the way, ushering in a new era of microwave signal sources that enable innovation. **_Due to the form-factor, the unit can also be used as a drop-in replacement of the obsolete “QuickSyn Synthesizers” from NI._** ![](https://www.berkeleynucleonics.com/wp-content/uploads/web_model_805-sg_comparison_chart.png) ##### [Features](#features-section) ##### [Specifications](#specifications-section) ##### [Options](#options) ##### [Tech Resources](#technical-resources-section) ##### [Media](#media-section) ##### [Downloable Resources](#downloadable-section) ##### [Price List](#pricelist-section) #### Overview ##### Features - Microsecond switching speed - Low-phase noise and low spurs level - Portable battery operation - Low level error accuracy - Compact RF signal source ##### Applications - **QuickSyn FSW-0010/0020 replacement** - ATE - Characterizing antennas, semiconductor devices and other components - Radar signal generation & Electronic warfare - Local oscillator for frequency converter application #### Specifications **Frequency Range** 100 kHz (8 kHz with option 8K) to 20 GHz **Frequency Resolution** 0.001 Hz **Power Range** -20 to +16 dBm **Power Resolution** 0.01 dB **Switching Speed** 500 µs (20 µs with option FS) **Phase Noise at 1 GHz: at 10 Hz offset** -87 dBc/Hz **Phase Noise at 1 GHz: at 1 kHz offset** -133 dBc/Hz **Remote Control** Ethernet, SPI, USB 2.0 **Modulation** Pulse **Sweeps** Frequency, Power, List **Dimensions (W x L x H), Weight** 7.0 x 5.0 x 1.0 in, 2.2 lbs #### Options 8K Frequency range extension to 8 kHz FS Ultra-fast switching speed PULSE Internal / External Pulse Modulation #### Technical Resources [ Part Numbering - RF Synthesizer](https://www.berkeleynucleonics.com/download/21511/?tmstv=1778700938) [ Press Room - BNC Product Launch | 22 GHZ Compact Multi-Channel Phase-Coherent Frequency Synthesizer](https://www.berkeleynucleonics.com/download/26061/?tmstv=1778700938) [ BNC Model 805-SG Signal Generator Datasheet v104](https://www.berkeleynucleonics.com/download/26068/?tmstv=1778700938) #### Downloadable Resources Downloadable resources such as datasheets, firmware, software, drivers and products manuals.
