Figure 42 iPA RTF Settings screen (Local control)
8.7.1 Slider Controls (iPA)
Slider controls can be touched and moved on touchpad devices or moved with the mouse on PC-based browsers. These
change the frequency range that the F1 and F2 tones are swept over.
8.7.2 Adjust Upper and Lower Frequency Limits (iPA)
These can be entered via the touch PC virtual keyboard or the PC keyboard.
8.7.3 Cable Velocity Factor
The velocity factor (VF) is a fundamental property of the RF cables in the system under test, which affects the speed at
which signals travel through the system. The velocity factor varies from cable to cable, but its value is always greater than
zero and less than or equal to one. An incorrectly specified velocity factor will introduce a distance measurement error into
both the PIM vs Distance and Return Loss vs Distance results.
8.7.4 Max Range
This establishes the maximum distance at which the instrument can detect PIM & Return Loss faults without error., Max
range can be represented in either meters or feet. The desired measurement units can be selected on the main settings/
miscellaneous menu.
8.7.5 PIM Product Menu
Use the Product pull down menu to select the Intermodulation Product to be tested, i.e. IM3 or IM5.
8.7.6 OK Button
Once you have completed adjusting the settings Press OK to enter the new values and return to the previous menu.
8.7.7 Cancel Button
Pressing the Cancel button will allow you to return to the previous menu without using any changes to the settings.
