All LAB105 TDR probes are light weight and slim. This is a unique characteristic and can be benefited when hand held measuring. However, hand held probing is difficult to pin point the same spot. W2000A is a probe station which holds the probe and through its universal joint design, any location can be easily probed. This eliminates the deviation caused by human factors such as, slightly probing spot deviation, contact force difference, probing angles.
