4.5.2. Off-hook insertion loss:
The insertion loss of a device connected into a given transmission system is defined as
the ratio, expressed in dB, of the load power available ( before and after insertion )
delivered to the output network beyond the point of insertion at a given frequency. In
general, the insertion loss is defined as the ratio, expressed in dB of the power delivered
to a load with the circuit in place and the power delivered to a load without the circuit in
place. The added insertion loss shall be measured using the test up in figure 2. For
measuring POTS band insertion loss for single filter module also for single filter with four
added parallel load filters. General Insertion loss equation can be expressed as follows.
Insertion loss = 20 log V2 / V1 dB where
V1 = the measured voltage value of load without LPF in circuit.
V2 = the measured voltage value of load with LPF in circuit.
The test setup is shown in drawing below.
