Device for testing printed boards

A tester for testing a large-area, non-componented printed circuit board having a plurality of test points, comprising:

• an electronic analyzer comprising a plurality of test connections;
• a grid base having a side provided with a grid pattern comprising a plurality of contact points arranged in a predetermined pattem, each of said contact points being electrically connected to at least one of a plurality of straight-line scanning channels, wherein several of said contact points are electrically connected to each straight-line scanning channel and wherein an electrical connection can be made between said test points and at least some of said contact points when an adapter and/or a translator is mounted between said grid pattern and said printed circuit board being tested;
• and
• a means for electrically connecting a plurality of scanning channels together to form groups of electrically connected scanning channels, wherein each group of electrically connected scanning channels is connected to one of said test connections of said electronic nalyzer.
