Its also useful to determine how many times the signal is split on a specific run. Some installation practices only allow at most a 2 way split, so determining if there are multiple splitters is very important. Yes, the CableIQ can detect the presences of splitters in a coax system, but not always show their location output branches must be un-terminated.
In the past, detecting the presence of splitters, their quality and the number of splits has been very difficult to do without specialized test equipment. However, the technology implemented in the CableIQ now allows this information to easily be determined. The TDR trace will contain information to generally assess the quality of the splitter and how many times it is split. TDR is like radar and signals reflect off each point where there is an impedance change. If the impedance change goes higher, for example an open circuit, the reflection is positive.
If the change in impedance is lower then the reflection is negative. The size of the reflection is a function of the size of the impedance change. With this simple knowledge, a user can view the TDR trace and determine if there are impedance mismatches due to a splitter and how many times a signal is split.
Consider the following example of coax cabling which has a 2 way splitter being tested by a CableIQ Figure 2. It has three branches of lengths L1, L2 and L3 respectively. L2 and L3 are connected to the output ports of the splitter and are un-terminated. Figure 2: Example coax cabling test configuration with a splitter. Figure 3 shows the display with the Splitter or Fault warning that will be present if the CableIQ suspects a splitter is in the cabling under test.
This is the cue to the user that the Coax TDR trace should be viewed for further information. An ideal or high quality splitter has the characteristic of looking like a 75 ohm impedance device across a wide frequency range on input and output ports.
Therefore, when hooked into a 75 ohm cable system there will be little to no reflection at the splitter since there isnt an impedance change. Only the reflections off the un-terminated ends of the output branches will be seen. There should be one and only one reflection for each branch.
The reflections should occur at the sum of the length of the input and respective output branches. There are only two reflections. This is and indication the splitter is of good quality since there is no reflection for the splitter itself.
The two reflections indicate that there is only a 2 way split. Note in the case of a good splitter the CableIQ may not be able to locate it since there is no reflection off a good splitters, but it can detect there is a splitter in the cabling.
However, sometimes even in the case of a good splitter there may be a slight reflection that allows the user to determine the location of the splitter. Low quality splitters do not provide a good wideband impedance match on all its ports and generally generate a low impedance reflection at the point of the splitter.
This will produce a negative reflection.
