  We have examined the effects of embedded pitch adapters on signal formation
in n-substrate silicon microstrip sensors with data from beam tests and
simulation. According to simulation, the presence of the pitch adapter metal
layer changes the electric field inside the sensor, resulting in slowed signal
formation on the nearby strips and a pick-up effect on the pitch adapter. This
can result in an inefficiency to detect particles passing through the pitch
adapter region. All these effects have been observed in the beam test data.
