Math, okay here is a little chart i made for myself. Picture below.
(1) All the dots (heavy dots) are connected to the Ground. And the Ground
is connected to the ground of the two "center" SMA jacks (the one on the
left side of my pic, and the one on the right side).
(2) The 4 circles show how those 4 pairs of holes are connected. (Each pair
is an independent connection to the other member of the pair.)
(3) The top and bottom SMA jacks (in my picture, not yours) are not
connected to the 'holes' at all. They connect to the solder pads on the
surface.
Apparently you can solder surface-mount components to customize your board.
Maybe 50 or 100 ohm SMD resistors, or whatever.
(4) The holes marked X (in my chart) connect to the center conductor of the
SMA jack on the right side (of my photo), or to the center conductor of the
SMA jack on the left side.
If you ask me, the board is too small, but it can be used perhaps with a
breadboard to provide more space for connections.
Hope this is helpful. Without the chart, i would be baffled.

I can not find any info on how to calibrate or measure components with
this test board.
Could someone help me please?
