This paper addresses simultaneous high-precision measurement and analysis of generic reference signals by using inexpensive commercial off-the-shelf software-defined radio hardware. Sine reference signals are digitally downconverted to baseband for the analysis of phase deviations. Hereby, we compare the precision of the fixed-point hardware digital signal processing chain with a custom single instruction multiple data x86 floating-point implementation. Pulse reference signals are analyzed by a… CONTINUE READING

Key Quantitative Results

  • Applying standard 10 MHz and 1 PPS reference signals for testing, a measurement precision (standard deviation) of 0.36 and 16.6 ps is obtained, respectively.
