Embodiment Construction
[0053] Attached below picture The present invention is further described in detail with specific examples.
[0054] Such as Figure 8 As shown, the new high-precision dielectric constant test system based on microwave sensors includes a wide-bandwidth signal sweep source, a differential sensor, a frequency discrimination phase (data conversion) module, and a data storage module.
[0055] Wide-bandwidth dual-port signal sweeping source (or single-port sweeping source outputs two-way sweeping signals after passing through a power divider) outputs two equal-amplitude 0dBm measurement signals, which are input to differential sensors; differential sensors output two-way power signals to the frequency and phase detection (data conversion) module; the frequency and phase detection (data conversion) module outputs two DC voltage signals, which are finally stored in the data storage module. The data storage module can upload it to the client for data analysis and data post-processing...
