为在欠采样率条件下实现高频信号的测量与恢复,本文使用自研国产皮秒级等效时间采样光取样示波器对频率10~100 GHz的简谐波信号进行采集和恢复。该示波器中,分别采用粗、细两级延迟进位产生延迟分辨率5 ps、动态范围10 μs的触发序列,驱动高带宽取样器对信号进行取样,取样信号通过50 kHz 模数转换器输出得到测量值,即每间隔20 μs增加5 ps延迟的方式对高频信号进行一次取样,压缩比约为10

,实际采样率远低于奈奎斯特定理限制。根据压缩感知原理,通过傅里叶变换及等效时间采样构成测量矩阵,构成该信号测量过程的稀疏化表示,并求解L1范数最小化问题,恢复得到被测信号波形。结果表明,最高可实现100 GHz的高频信号均方根误差小于5×10

A simple harmonic wave with frequency 10–100 GHz is collected by a domestic equivalence time optical sampling oscilloscope to measure and recover high-frequency signals in undersampling situations. There is a trigger sequence with a 5 ps delay resolution and 10 μs dynamic range in the oscilloscope. The trigger sequence, generated by two steps of coarse and fine delayers, is used to drive the high band-wide sampler, and the sampling value is output by an ADC with a frequency of 50 kHz. In this advancement, the high-frequency signal is sampled with an increasing 5 ps delay every 20 μs. The compress ratio is approximately 10

, and the sampling rate is far below the Nyquist law. With compressive sensing theory, the measurement matrix is constructed by Fourier translation and equivalence time sampling sequence and sparsify the signal measurement process. The measurement signal is reconstructed by solving an L1-norm minimum problem. The results demonstrate that the signal with a frequency of 100 GHz can be undersampled and reconstructed with a mean square error below 5×10

, implying that the dynastic range of the sampling oscilloscope should be expanded.
