DO NOT block air vents.
Due to its high RF output power, PIM31 consumes up to 750W.
This energy has to be disposed. While these test systems have
protection against overheating, it is vital to keep air vents clear of
any obstructions that would prevent or limit the air flow.
Air vent locations
• Front Panel
• Back Panel
• Bottom
Keep clearance at least 15 cm / 6 inches for Front and Back Panel
Vents, and 4cm / 1.5 for the bottom vent.
DO NOT bent cable tighter than 40 cm / 16 inches of diameter.
Cables that come with the PIM31 offer a combination of high
quality, low PIM, and high reliability. The test cable is a vital piece
of the measurement setup, and a damaged or worn cable will
influence PIM measurements... The structure of Boonton’s PIM
cable offers customer friendly utilization in the field and in the
factory it allows for a bending radius of 20 cm / 8 inches. Tighter
bending will permanently alter the cable structure, which will cause
performance loss and can cause permanent PIM, rendering the
cable unusable. See also chapter: Using the Cable.
DO NOT over-torque the RF Port connector and accessories.
The best performance of RF connectors is achieved when the
connections are made with the correct torque. Too much of a
torque can permanently deform PINs and connections areas, too
little torque can hinder the electron flow, varying the impedance or
in some cases can cause spark discharge. All these effects can
damage the components permanently. To ensure proper
connections always use the torque-wrench that comes standard
with the PIM31.
