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.
