Problems solved by technology
[0003] However, conventional pulse signal generators generally only provide single-channel or dual-channel pulse output. Even if the pulse performance is good, the precision is high, and the functions are complete, there are certain limitations and it is difficult to meet some special application needs.
If more than two channels of pulse signal output are required at the same time, even if multiple instruments work at the same time, there are problems in signal synchronization, and at the same time, it is impossible to adjust the delay relationship of multiple channels of pulse signals

Description
technical field [0001] The invention relates to a pulse signal generator, in particular to a device and method for generating multi-channel video pulse signals. Background technique [0002] With the rapid development of electronic technology, high-speed pulse signal generator has been widely used as an important experimental instrument in the fields of communication, radar, measurement and control, precise control and electronic countermeasures. At this stage, there are not many types of dedicated pulse signal generators, because the design purposes and indicators are different, and the performance is also different. Some general signal sources also have the pulse signal output function. General instruments can generate pulse signals with adjustable pulse width, pulse period and pulse amplitude, and some instruments also have functions such as variable pulse edge time, bipolar pulse output, and external triggering. [0003] However, conventional pulse signal generators gen...
