| description | In order to realize the waveform reconstruction of high-frequency signals under under-sampling conditions, the generation of progressive delay ultra-narrow trigger signals has become the key to the use of sequential equivalent sampling techniques for high-frequency signal sampling in trigger sampling systems. To this end, a programmable delay trigger sequence generation and conditioning circuit is designed. Under the control of the FPGA digital circuit, an adjustable delay trigger sequence is generated through the counter and delay module, and the step recovery diode characteristic is utilized to condition the generated trigger sequence to produce a pulse signal with adjustable delay step and extremely narrow edge. By testing the circuit, the results show that the output pulse signal step range is adjustable between 0~2.4 ns, the resolution can be up to 1 ps, the edge jump time can reach within 120 ps, and the amplitude is about 8 V. The delayed pulse and conditioning circuit can be applied to communications, radar and other signal detection equipment, and has great significance for the acquisition and analysis of high-frequency signals. |
