How to set up the Mini GPSDO as an External Clock Reference for the VNWA 3EC: Guide to setting up Mini GPSDO as external reference clock, instead of internal VNWA TCXO when taking VNWA measurements. How to make high accurate precision frequency with the VNWA Thanks to Kurt Poulsen for preparing this report and sharing his expertise. ![]() Powered via mini USB connector from a PC, USB phoneĬharger or USB power bank.Output power level (measured at 10MHz, fundamental power channel): Output signal is 3.3V CMOS levels with 50 Ohms characteristic impedance. Providing high-quality, low phase noise clock signal with sub-picosecondĭigital PLL allows main output reference frequency to have almost any value between 400Hz and 810MHz. Short term signal quality is defined by internal TCXO clock source Long term stability of output signal is defined by high accuracy of GPS Caesium references and approaches 1x10 -12 To make Frequency and Frequency Difference measurements with accuracyĪpproaching 1e-10 and frequency measurements ( dF) in the mHz (milli Hertz) and even down to the uHz (micro Hertz) region.Īlso, the Mini GPSDO can be used as an external clock for the SDRplay RSP2 or RSP2pro with our GPSDO - RSP2 External Clock Cable SDR-Kits recommends either version as the ideal frequency standard for supplyingĪn external reference clock signal to the DG8SAQ Vector Network Analyzer Like its big brother, the Mini Precision GPSDO Reference Oscillator can be used asĪn Universal Reference Clock for most other Instruments andĪpplications which up to now would require a bulky and expensive Rubidium ![]() Restrictions, whilst still delivering accuracy and performance. Low jitter GPS Clock - designed for Users with a limited budget or space Mini Low Jitter Precision GPSDO Reference Oscillator (1 Port)Ī new mini version of Leo Bodnar's popular
