Prepare for ETA PIM with antenna installation quality, PIM test-set operation, RF safety, system and component tests, PIM sources, static and dynamic testing, dB/dBm/dBc, two-carrier test levels, reports, hands-on requirements, 50 questions, and 2-hour timing.
PIM is ETA International's stand-alone hands-on credential for technicians who verify antenna installation quality, operate passive intermodulation test equipment, and troubleshoot site PIM interference issues.
Use these checkpoints to confirm the current format, delivery rules, scoring, and test-day setup before building the full plan.

ETA PIM validates passive intermodulation testing knowledge and hands-on skill for antenna systems, including PIM test equipment use, antenna theory, interference testing, site troubleshooting, and safe test execution.
ETA Press lists PIM as a stand-alone certification with maintenance required, a 4-year term, hands-on required, 50 questions, a 75% passing score, and 2 hours allowed to test.
Study PIM definitions, radio-circuit terminology, KPIs, carrier and manufacturer test procedures, system versus component tests, dB, dBm, dBc, radiated and non-radiated power, intermodulation, spurious emissions, receiver desense, antenna versus load behavior, line sweep, internal and external PIM sources, connectors, antennas, filters, combiners, and other network elements.
Preparation should include static and dynamic PIM testing, fixed and swept frequency methods, third-order intermodulation calculations, spectrum analyzer use, system tests with antennas and low-PIM loads, high-PIM and low-PIM load purpose, RF safety briefings, lockout/tagout, test-set verification, two-carrier power-level confirmation, noise floor interpretation, uplink receiver impact, state files, markers, location and sector labels, reports, and return-to-service clearance.

ETA Passive Intermodulation Testing (PIM) is an ETA International certification for technicians who verify antenna installation quality, operate PIM test equipment, and help resolve site PIM interference issues. ETA describes the certification as based on the IEC 60237 standard covering antennas, connectors, jumpers, and related antenna network elements, with the expectation that certified technicians can use any manufacturer's test set at any frequency range.
ETA Press lists PIM as a stand-alone certification with maintenance required, a 4-year term, hands-on required, 50 questions, a 75% passing score, and 2 hours allowed to test. Preparation should cover PIM in radio circuits, network element terminology, key performance indicators, carrier and manufacturer methods, system versus component testing, dB, dBm, dBc, radiated and non-radiated power, intermodulation, spurious emissions, receiver desense, antenna versus load behavior, antenna line sweep, internal and external PIM sources, connectors, antennas, filters, combiners, static and dynamic PIM testing, fixed-frequency and swept-frequency PIM tests, third-order intermodulation calculations, spectrum analyzer use, system testing with antennas and low-PIM loads, RF exposure safety, PIM test head clearance, radio outages, lockout/tagout, test-set verification, two-carrier power levels, noise floor interpretation, uplink receiver impact, state files, markers, location and sector labeling, report generation, and post-test clearance restoration.
ETA Passive Intermodulation Testing (PIM) is a stand-alone ETA International credential for technicians who verify antenna installation quality, use PIM test equipment, and troubleshoot passive intermodulation interference at radio sites.
ETA Press lists the PIM exam at 50 questions with 2 hours allowed to test.
ETA Press lists a 75% passing score for the Passive Intermodulation Testing certification.
Yes. ETA Press lists hands-on required for PIM, so candidates should confirm current practical testing and documentation requirements before scheduling.
Study PIM sources, antenna and network elements, dB/dBm/dBc, radiated and non-radiated power, intermodulation products, receiver desense, static and dynamic PIM testing, fixed and swept frequency tests, spectrum analyzer use, RF safety, lockout/tagout, two-carrier power levels, noise floor interpretation, reports, and return-to-service procedures.
Verify the current ETA hands-on pathway, acceptable documentation, required equipment, approved training facility expectations, and test-day sequence before scheduling.
Practice distinguishing internal and external sources, multiple-source conditions, connector and antenna issues, filter or combiner effects, and site conditions that create PIM.
Review tailboard conferences, RF exposure, PIM test-head clearance, test duration, radio outage procedures, and lockout/tagout before any test scenario.
Calculate third-order intermodulation products, compare dBm and dBc, verify two fixed carriers, place test markers, and interpret noise floor changes.
Practice producing reports with setup state files, location and sector labels, carrier requirements, markers, results, exported files, operator clearances, and post-test return-to-service notes.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
