Low-cost trigger circuit for sampling oscilloscope
Aleksander Burd, Katarzyna Opalska · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2007
The paper presents a low-cost trigger circuit for use in sampling oscilloscope with bandwidth in order of hundreds of MHz. The presented dual-step trigger circuit provides relatively high bandwidth because of significant reduction of possibility of incorrect turning on in trigger circuit flip-flop (caused by circuit instability called tremor or - describing the same phenomenon by other means - its metastability. The paper presents a circuit structure, principle of operation and its physical realization.
