Cable Assemblies
The RTF module is supplied with the following cable assemblies:
Short USB Cable
The short USB cable is for use with C-series iQAs and the iPA. It connects the RTF module to USB Port 3 on the front
panel of the iQA and the Type A USB connector on the iPA.
Long USB Cable
The long USB cable is for use with A- and B-series iQAs that have had the RTF upgrade kit installed. It connects the RTF
module to USB Port 1 or USB Port 2 on the front panel of the iQA.
Monitor Cable
The Monitor cable is a low-power RF cable that connects the AUX port on the RTF module to the Monitor port on the front
panel of the iQA. Its purpose is to carry the measured PIM signal and 12V DC power from the iQA to the RTF module.
Current Production iPAs are shipped with a N Type to SMB cable to connect the RTF module to the iPA. If your N-to-SMB
cable has been lost or damaged, a replacement cable can be ordered from Kaelus (part no. R18-0768-500).

Connecting the RTF Module to the iQA
The RTF module can be connected or disconnected from the iQA at any time, without risk of damage to either piece of
equipment.
The connection procedure is as follows:
1. Attach the RTF module to the iQA’s RF Output port and tighten the RF connector. Do not allow the body of the RTF
module to rotate while tightening the connector, as this can cause damage to the 7-16 connector mating surfaces.
The recommended orientation of the RTF module is shown in Figure 4.
2. Connect the AUX port of the RTF module to the iQA’s Monitor port using the cable provided.
3. Connect the USB port on the RTF module to any one of the USB ports on the iQA’s front panel using the cable
provided.
