●
The voltage of the pulse generator can be changed between 50V to 400V continuously, so that
no matter thin plate or hard-penetrated work-piece can be matched with the most fitful probe.
●
The width of the pulse can be change d between 25ns to 1000ns continuously, so that the best
sensitivity can be realized with the help of different probes with different frequency.
Damping
can be changed among 4 levels: 33/50/100/500Ω, so that the best performance of the
probe can be attained and the different requirements of the sensitivity and resolution can be realized.
Wave signal filter
can be changed between 2 levels: 1-4MHz/0.5-15MHz. Each individual
advantage of narrowband and broadband filter can be achieved.
Repeating frequency
can be changed freely to avoid unreal signal.
