PIM Radio Frequency ON Light (item 1 in Figure: PIM Master Top Panel Layout)
This red indicator is illuminated when PIM RF output power is On.
PIM Test Connector (item 2 in Figure: PIM Master Top Panel Layout)
Type 7/16 DIN(f), 50 Ω test port connector that is used to perform PIM versus Time, Swept PIM, Noise Floor, and Distance‑to‑PIM (DTP) measurements.
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the DIN connector. Do not over-tighten the connector. The recommended torque is 25 N · m (~18 lbf · ft). To prevent rotation, secure the PIM test connector or the recommended connector saver with a wrench when attaching a test lead.
Refer to Connector Saver.
