Prepare for ETA LAS with RF and microwave transmission-line testing, cable and antenna analyzers, FDR use, return loss, VSWR, resonance, swept frequency, DTF, insertion loss, cable loss, hands-on requirements, 75 questions, and 2-hour timing.
LAS is ETA International's hands-on RF sweep testing credential for professionals who verify coaxial transmission lines and antenna systems using frequency domain reflectometers and cable and antenna analyzers.
Use these checkpoints to confirm the current format, delivery rules, scoring, and test-day setup before building the full plan.

ETA LAS validates the ability to conduct line and antenna sweep tests and fault-location measurements on RF and microwave transmission lines and antenna systems, especially coaxial systems used at communication sites.
ETA Press lists LAS as a stand-alone certification with maintenance required, a 4-year term, hands-on required, 75 questions, a 75% passing score, and 2 hours allowed to test.
Study reflected RF energy, return loss, VSWR, resonance, swept frequency, distance-to-fault, insertion gain, insertion loss, cable loss, coaxial line behavior, antenna verification, connector faults, and trace interpretation.
Preparation should include analyzer setup, calibration, reference plane control, cable and antenna analyzer operation, clean documentation of sweep results, and safe work practices around RF systems and tower or rooftop environments.

ETA Line and Antenna Sweep (LAS) is an ETA International certification for professionals who conduct sweep tests and fault location measurements of RF and microwave transmission lines and antenna systems. ETA describes the test equipment as frequency domain reflectometers or cable and antenna analyzers and expects candidates to understand field measurement of coaxial transmission lines and antennas.
ETA Press lists LAS as a stand-alone certification with maintenance required, a 4-year term, hands-on required, 75 questions, a 75% passing score, and 2 hours allowed to test. Preparation should cover RF energy measurement principles, reflected RF energy, return loss, VSWR, resonance, swept frequency, distance-to-fault (DTF), insertion gain and insertion loss, cable loss, coaxial transmission line behavior, antenna system verification, cable and connector faults, analyzer setup, calibration, trace interpretation, field documentation, and safe RF/tower-site work practices.
ETA Line and Antenna Sweep (LAS) is a stand-alone ETA International credential for professionals who perform sweep tests and fault-location measurements on RF and microwave transmission lines and antenna systems.
ETA Press lists the LAS exam at 75 questions with 2 hours allowed to test.
ETA Press lists a 75% passing score for the Line and Antenna Sweep certification.
Yes. ETA Press lists hands-on required for LAS, so candidates should confirm the current practical requirement and documentation process before scheduling.
Study RF energy measurement principles, return loss, VSWR, resonance, swept frequency, distance-to-fault, insertion gain and loss, cable loss, analyzer setup, calibration, trace interpretation, antenna verification, cable faults, and field documentation.
Before scheduling, verify the current ETA hands-on pathway, required equipment, evaluator expectations, and any course or proctor documentation needed for LAS.
Be able to connect reflected energy concepts to return loss, VSWR, resonance, mismatch, and what those readings imply about line or antenna condition.
Work through FDR or cable and antenna analyzer setup, calibration, frequency-range selection, limit lines, trace saving, and common setup mistakes.
Use DTF and sweep traces to identify likely cable, connector, antenna, water intrusion, bend, or termination issues and decide what field action follows.
Practice writing concise sweep reports that include setup conditions, pass/fail observations, trace evidence, corrective actions, and retest results.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
