A further test involves testing the drop cable section of the residential system. The drop
cable is disconnected from the ground block and the drop cable is connected to the precision
receiver. With the mobile transmitter powered on and the receiver tuned to the frequency of
the transmitter, the level of test signal is measured. The level of the received test signal is
compared to a reference standard to determine if the shielding integrity of the drop cable is
acceptable. Test signal level measurements may be indicated by the receiver in common
units of measurement, such as µV or dBmV. The receiver may automatically perform the
level comparison function and produce a Pass/Fail message. A greater than acceptable level
measurement would most likely indicate a faulty connection at the local tap.
