Manufacturered
by Leo Bodnar LTD, the Low-jitter GPS-Locked Precision Frequency
Reference Oscillator can be programmed to two output frequencies between
400 Hz up to 800 MHz with a stability of better than 1e-9 (1 part per
billion (ppb) within 1 minute after achieving lock to the high accuracy
GPS Satellite Network which is controlled by a Caesium Clock with
accuracy approaching 1e-12
USB
powered, this instrument is 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.
The 2 port GPSDO can be used as an external clock for the SDRplay RSPdx, RSPduo and the older RSP2 or RSP2pro with our RSP Clock-in cable
Light
and portable, the 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.
Two synchronized low-jitter reference clocks locked to GPS signal, Digital PLL allows main output reference frequency to have almost any value between 400 Hz and 800 MHz.
Two outputs can be individually enabled and set to different frequencies. Second output frequency depends on the first output. If both outputs have the same frequency their relative phase shift can be adjusted. This can be used, for example, to generate two signals with 90° phase shift for use in I/Q mixer.
Both output signals are at 3.3V CMOS levels with 50 Ohms characteristic impedance. Their output drive levels 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- Short term signal quality is defined by internal 0.5 ppm TCXO clock source
providing high-quality, low phase noise clock signal with sub-picosecond
RMS jitter
- USB Powered or +5V External PSU. Current drawn: Max: 0.27 Amp
How to set up the GPSDO as an External Clock Reference for the VNWA 3EC: Guide to setting up GPSDO as external reference clock, instead of internal VNWA TCXO when taking VNWA measurement
