A new 400 Hz to 810 MHz output mini version of Leo Bodnar's popular low jitter GPS Clock - designed for Users with a limited budget or space restrictions, whilst still delivering accuracy and performance.
Long term stability of output signal is defined by high accuracy of GPS Caesium references and approaches 1x10-12
Short term signal quality is defined by internal TCXO clock source providing high-quality, low phase noise clock signal with sub-picosecond RMS jitter.
Digital PLL allows main output reference frequency to have almost any value between 400Hz and 810MHz.
Output signal is 3.3V CMOS levels with 50 Ohms characteristic impedance. Output drive level can be adjusted.
Output power level (measured at 10MHz, fundamental power channel):
- +13.3dBm, drive setting 32mA
- +12.7dBm, drive setting 24mA
- +11.4dBm, drive setting 16mA
- +7.7dBm, drive setting 8mA
- Powered via mini USB connector from a PC, USB phone charger or USB power bank. USB connection to Windows PC is required only for one-off configuration.
Like its big brother, the Mini Precision GPSDO Reference Oscillator can be used as an Universal Reference Clock for most other Instruments and Applications which up to now would require a bulky and expensive Rubidium Clock.
SDR-Kits recommends either version as the ideal frequency standard for supplying an external reference clock signal to the DG8SAQ Vector Network Analyzer to make Frequency and Frequency Difference measurements with accuracy approaching 1e-10 and frequency measurements (dF) in the mHz (milli Hertz) and even down to the uHz (micro Hertz) region.
Also, the Mini GPSDO can be used as an external clock for the SDRplay RSP2 or RSP2pro with our GPSDO - RSP2 External Clock Cable
note however that a SMA Plug to BNC Jack Adapter Connector, or similar is required to connect the External Clock Cable to the Mini GPSDO
