PIM Cheat Sheet 2026: One-Page Review of Must-Know Facts

What This Cheat Sheet Covers (and What It Doesn't)

This page is a compressed review of Passive Intermodulation Testing (PIM), the vendor-neutral, stand-alone certification offered through ETA International. It is a one-page memory aid, not a replacement for training. If you want the full learning path, start with the PIM Study Guide 2026; if you want the long-form treatment of scope, the PIM Exam Domains guide goes deeper than a cheat sheet can.

Everything below is anchored to ETA's published materials: the PIM section of its communications certifications page, the PIM Competencies Requirements document, the one-page fact sheet, the maintenance page, the general FAQ, and the certification pathway page. Where those sources disagree or leave gaps, this sheet says so rather than guessing.

The One-Glance Exam Snapshot

Print this table and tape it above your desk. It captures every hard number the published sources support.

Two cautions on that table. First, the 75% figure is a passing requirement, not a pass rate. No official PIM cohort pass rate has been verified, and commercial "success rate" claims are not ETA data; see the PIM Pass Rate discussion for how to read such claims. Second, the two-hour figure describes the written exam only. It says nothing about how long the practical assessment or the training course takes.

For the cost picture beyond the $130 exam fee, the PIM Certification Cost breakdown separates what is published from what depends on your chosen training provider.

The Seven Competency Headings

ETA's competency document lists seven numbered headings. They are unweighted: ETA does not publish percentages per domain, so do not trust any site that quotes domain weights for this exam. A separate Terms and Acronyms appendix is supporting scope, not an eighth numbered domain.

Core Concepts to Memorize Cold

The big idea

Passive intermodulation is unwanted signal generation by components that are not supposed to create signals at all: connectors, cables, antennas, and similar passive hardware. When two or more signals pass through a nonlinear junction, new frequencies appear. If those new frequencies land in a receive band, they raise the noise floor and degrade performance. That causal chain (multiple carriers, a nonlinearity, interfering products, degraded reception) is the thread running through Domains 1 through 3.

Vocabulary that carries over

Because the Terms and Acronyms appendix supports the whole scope, treat vocabulary as a daily habit instead of a last-week cram. Build a short glossary from the competency document itself and quiz yourself until the terms are automatic. Questions in later domains assume you already speak the language.

Connecting the dots across domains

• Sources (3) feed Testing (4): knowing likely causes tells you where to look and how to set up.
• Testing (4) feeds Interpretation (6): a measurement is only useful if you can read it.
• Interpretation (6) feeds Documentation (7): conclusions must be recorded in a form someone else can rely on.
• Safety (5) wraps everything: no test procedure is complete without safe practice.

If you are wondering how demanding all this is in practice, the PIM difficulty guide frames it honestly without inventing numbers.

Test-Day Rules and Logistics

ETA's general testing FAQ sets the ground rules, and they apply to a PIM sitting:

• Photo ID is required. Bring a valid one.
• Phones are prohibited. Plan to leave yours out of reach.
• Scratch paper is permitted, and you must surrender it when you finish.
• Calculators: non-programmable or scientific models are allowed. Programmable calculators may require a reset or battery removal.
• Delivery: ETA Certification Administrators administer onsite theory testing through Trapeza online testing or paper-and-pencil.

ETA's general FAQ also offers remotely proctored theory testing through Exam Room.AI. Treat that as a general ETA policy; it is not a separately retrieved PIM-specific remote-testing handbook, and it does not replace the required hands-on attendance at an ETA-approved school. Ask your administrator what applies to your sitting. For scheduling mechanics, see the PIM exam dates and scheduling guide.

Pacing is straightforward arithmetic from the published format: 50 questions in 120 minutes leaves roughly two and a half minutes per question on average. Don't let one hard item eat the time of several easy ones. ETA's materials do not specify a question-type breakdown for this exam, so avoid assuming one, and practice with a mix of formats through the PIM practice tests.

The Hands-On Half of the Credential

This is the part of the process that catches people off guard. Passing the written exam is not the whole credential. You also need an ETA-approved hands-on training course and practical verification. Those carry their own charges and their own duration, separate from the $130 exam fee and the two-hour written test.

The stand-alone pathway means you do not need the Associate Certified Electronics Technician (CETa) or another basic electronics certification first. That lowers the entry barrier, but it does not remove the hands-on requirement. For the full eligibility picture, read PIM Requirements: eligibility and how to qualify, and for the training side, the PIM training overview.

Four-Year Validity and Maintenance Math

The credential is valid for four years, with maintenance. Under ETA's Maintenance with Hands-On category, the published requirements are:

On-the-job training is subject to employer verification and ETA evaluation. Don't substitute requirements from other maintenance categories (such as a general non-hands-on hour total) or exceptions that apply only to other credentials; those do not govern this category. If you are weighing long-term value, the ROI analysis and the salary guide discuss the career side, and the PIM jobs overview covers where the skill gets used.

Source Quirks Worth Knowing

ETA's public documents contain a few inconsistencies. Knowing them keeps you from being thrown by a stray reference.

• Safety heading wording: The undated fact sheet uses "PIM Safety Overview," while the more detailed competency document says "RF SAFETY OVERVIEW." The detailed document controls, so study to the RF Safety Overview heading.
• Fact sheet bullets: The one-page fact sheet has eight summary bullets, including Key Terms and Acronyms. The competency document has seven numbered headings. The appendix is supporting scope, not a numbered domain.
• Standard citation: ETA's page and fact sheet cite IEC 60237, whereas IEC's passive-intermodulation series is IEC 62037. This sheet does not treat the ETA reference as independently verified.
• IEC 62037-1:2025: The public catalogue description does not establish a new ETA exam blueprint, and the paid standard was not retrieved. Don't assume the exam changed because a standard was revised.
• Document age: The competency document carries a 2013 copyright. A seller's claimed "2025 update" is not an issuer-verified revision.
• PDF metadata: The competency PDF contains an unrelated legacy title in its metadata, but all three visible pages identify PIM, and the visible content governs.
• Rollover pathway: A separate $130 rollover exists for current Anritsu PIM holders. That is a different pathway, not the standard examination described here.

Mapping the Domains to a Study Calendar

Generic scheduling advice is cheap; what helps is ordering the domains by dependency. Because Sources feed Testing and Testing feeds Interpretation, study them in that sequence rather than at random. Here is one possible four-week arrangement.

Adjust the pace to your background and to when your hands-on course falls. Use the practice test platform for timed runs, and see the passing score explainer for how to interpret your practice results against the 75% criterion without over-reading any single attempt.
