4.2 USING HIGH PERFORMANCE RF CABLES
Cables are as vital to proper PIM testing as any of the other accessories are. Treat them
with the appropriate care. All hints listed above for accessories apply to cables as well.
Always use cable caps to protect connectors when the cable is not in use. The bending
radius for the PIM-P cable delivered by AWT is 20cm / 8 inches. To prevent damage, coil
cable no tighter than 40 cm / 16 inches in diameter. A transit case for PIM-P systems is
available. This case has dedicated space for test systems, accessories and also the low PIM
cable. For more information please refer to the chapter on accessories.
“
Treat accessories and cables for what they are:
High precision measurement devices”
PIM tests measure the device in the testing path that generates the highest level of PIM.
Worn or malfunctioning accessories lead to inaccurate measurements. Remember you want
to measure the PIM level for the RF path or device under test, not a worn accessory or test
cable. Inspect your accessories and cables prior to each use, and treat them as part of a
high precision measurement device.
