Table 7.1 Calculation of the cable signal delays
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 measurement 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 connected to the same transmitter output.
5. Reconnect the cable t 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 difference 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 balcony, if applicable (see section 7.4.3 )
11. Set the delay switches to the calculated delay switch positions.
Figure 7.4 and Table 7.2 illustrate the calculation of the signal delays and the delay switch
positions.

4 30 5.6 30*5.6 = 168 280-168=112 112/33=3.39=3
5 30+20=50 5.6 50*5.6 = 168 280-280=0 0/33=0
NOTICE!
The used cable signal delay per meter is an example. Use the actual signal 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.
