Note: For systems with a cable length dif- ference of more than 50 meters, it is rec- ommended to use a measurement tool to determine the delay differences in order to calculate the delay switch positions.

Figure 1.26 and table 1.1 illustrate the calculation of the cable signal delay.

1.5.1.2 Determining delay switch positions by using a delay measuring tool

The most accurate way to determine the cable signal delays is to measure the actual signal delay for each radiator as described in the following procedure:

1.Disconnect the cable from a radiator output of the transmitter and connect this to a delay measure- ment tool.

2.Disconnect a radiator from this cable.

3.Measure the impulse response time (in ns) of the cable(s) between the transmitter and the radiator.

4.Reconnect the cable to the radiator and repeat steps 2 to 4 for the other radiators that are connect- ed to the same transmitter output.

5.Reconnect the cable to the transmitter and repeat step 1 to 5 for the other radiator outputs of the transmitter.

6.Divide the impulse response times for each radiator by two. These are the cable signal delays for each radiator.

7.Determine the maximum signal delay.

8.Calculate for each radiator the signal delay differ- ence with the maximum signal delay.

9.Divide the signal delay difference by 33. The rounded off figure is the delay switch position for that radiator.

10.Add delay switch positions to radiators under a bal- cony, if applicable (see section 1.5.3)

11.Set the delay switches to the calculated delay switch positions.

Note: The used cable signal delay per meter is an example. Use the actual sig- nal delay per meter in this calculation as specified by the manufacturer.

Caution: Turn the delay switches carefully to a new position until you feel that it clicks into position, to prevent that a switch is positioned between two numbers, which would result in a wrong delay setting.
