本文利用廉价的商用软件无线电硬件实现了通用参考信号的同时、高精度测量和分析。正弦参考信号被数字下变频到基带，用于分析相位偏差。在此，我们比较了定点硬件数字信号处理链与自定义的单指令多数据(SIMD)x86浮点实现的精度。通过一个软件触发器分析脉冲参考信号，该触发器精确定位斜率通过某个阈值的时间。该测量系统使用Ettus Research LLC的通用软件无线电外设(USRP)N210进行了实现和验证。采用10 MHz和1 PPS的标准参考信号进行测试，测量精度（标准偏差）分别为0.36ps和16.6ps。与标准PC硬件连接，该系统允许在数周内长期采集和存储测量数据。对目前用于正弦信号分析和脉冲信号分析的双混频器时间差法(DMTD)和时间间隔计数器法(TIC)进行了比较。此外，我们还表明，我们提出的基于USRP的方法优于高级数字采样示波器的测量。

英文摘要：
  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 down-converted 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 (SIMD) x86 floating-point implementation. Pulse reference signals are analyzed by a software trigger that precisely locates the time where the slope passes a certain threshold. The measurement system is implemented and verified using the Universal Software Radio Peripheral (USRP) N210 by Ettus Research LLC. Applying standard 10 MHz and 1 PPS reference signals for testing, a measurement precision (standard deviation) of 0.36 ps and 16.6 ps is obtained, respectively. In connection with standard PC hardware, the system allows long-term acquisition and storage of measurement data over several weeks. A comparison is given to the Dual Mixer Time Difference (DMTD) and Time Interval Counter (TIC), which are state-of-the-art measurement methods for sine and pulse signal analysis, respectively. Furthermore, we show that our proposed USRP-based approach outperforms measurements with a high-grade Digital Sampling Oscilloscope.
