Title:
WIDEBAND WIDE-FREQUENCY AGILE SIGNAL MEASUREMENT INSTRUMENT AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2018/032645
Kind Code:
A1
Abstract:
A wideband wide-frequency agile signal measurement instrument, comprising: a first frequency mixer and filter unit (404), used to perform a first frequency mixing process on an input signal; a second frequency mixer and filter unit (408), used to perform a second frequency mixing process on an output signal of the first frequency mixer and filter unit (404), and generate a fixed analog intermediate frequency signal; an ADC acquisition unit (409), performs quantization on the analog intermediate frequency signal to generate a digital intermediate frequency signal; an orthogonal transformation unit (410), used to perform orthogonal transformation on the digital intermediate frequency signal, so as to generate an IQ complex signal; a digital filter unit (411), used to perform digital decimation filtering on the IQ signal; a measurement and analysis unit (412), performs processing and analysis on the basis of the IQ signal outputted by the digital filter unit; a display unit (413), used to display measurement results and curves. The wideband wide-frequency agile signal measurement instrument and measurement method can implement measurement and analysis on a frequency agile signal having a frequency agile range greater than an analysis bandwidth of a superheterodyne instrument.
