Embodiment Construction
[0030] see figure 1 Shown, be the block diagram of tool main high voltage multi-point test equipment and method provided by the present invention, mainly comprise:
[0031] A high / low voltage switching device 1, the high / low voltage switching device 1 includes an array of high voltage switches SH and several low voltage switches SL, so that the voltage output mode of the high / low voltage switching device 1 is that of each group of high voltage switches SH and low voltage switches SL switch on and off;
[0032] A test channel group 2, the test channel group 2 includes multiple groups of test channels 21a-21n, each group of test channels 21a-21n is connected to a group of high-voltage switches SH and a low-voltage switch SL of the high / low voltage switching device 1, When the high-voltage switch SH is in the conduction state (ON), the low-voltage switch SL is in the non-conduction state (OFF), so that the single test channels 21a-21n can only selectively output high-voltage or ...
