Figure 3 C-series iQA and A-series iPA front panel connectors991011101112139. RF Output PortThe RF Output Port on the iQA/iPA front panel is a bidirectional RF port. The pair of high-power carriers areemitted from this port, while the reflected PIM signal from the system under test enter the iQA’s receiver via thisport.10. Monitor PortThe Monitor Port is normally connected to the AUX Port of the RTF module. It is used to transmit the measuredPIM signal and 12V DC power from the iQA/iPA to the RTF module.11, 12, 13. USB PortOne of the USB Ports on the iQA/iPA must be connected to the RTF module. For C-series iQAs the preferredchoice will usually be USB Port 3, due to its close proximity to the RTF module’s point of attachment to the iQA.For the iPA a single Type A USB connector is provided under a protective cover.Note that USB Port 3 is not provided on A- or B-series iQAs that have had the RTF upgrade kit installed. Forthose instruments either USB Port 1 or USB Port 2 can be used to connect the iQA to the RTF module.15© 2017 Infinite Electronics, Inc., All Rights Reserved.
