LMR Master Certification

Anritsu LMR Master Certification

The S412E LMR Master from Anritsu is a single instrument that combines all of the tools required to install, maintain, and certify Land Mobile Radio systems.

This four day instructor-led certification class will give students a complete overview of the S412E LMR Master, enabling them to fully utilize the many features and functions of this instrument. Live polling quiz questions and extensive use of hands-on labs throughout builds confidence and helps students become proficient using the instrument.

The entire first day is spent familiarizing the student with every facet of the Spectrum Analyzer mode plus coverage mapping. Hands-on mini-labs throughout the day familiarize students with every function immediately after covering the topic in lecture. Since decibels are the language of RF (radio frequency) measurements, the students also learn an easy way to calculate decibels in their head.

The second day of class covers RF interference scientifically but in an easy to understand format that teaches successful interference hunting techniques. The day culminates with a live interference hunt where each student must work independently to identify and locate their own distinct source of interference.

On day three, students will learn to test cables and antennas, tune Duplexers, and learn to interpret digital measurements (Eye Diagrams and Constellations). Each student will be given a cable, antenna and Duplexer during several hands-on lab activities.

Day four is spent covering optional topics such as P25, NXDN, DMR2, PTC and LTE signals, learn to use the Channel Scanner, GPS and Power Meter functions in the S412E as well as MST (Master Software Tools) to display measurements and create reports. A final review of all the quiz questions is conducted before the final written exam is given. Students that successfully complete the course receive an LMR Master Certificate of Completion and Photo ID Badge.

"The training was nothing short of exceptional. I feel like I learned more in one week than in a semester in college. Jeremy is an excellent instructor. This class was worth every penny and more."
- G. Jarvis, Student 2015

Price: $2,495 per student

Private, on-site classes in the U.S. typically require a minimum of 8 students.

Why Anritsu training?
  • Hands-on: Learn by doing!  Learn the theory and perform the measurements.  A significant portion of the course contains lab exercises with simulated signals and conditions measured with the S412E LMR Master.
  • Thorough Emphasis: Students will learn to perform typical measurements including Line Sweeping, Over-the-Air and demodulated RF measurements, power measurements, Interference Analysis, Spectrum Analyzer based measurements, and duplexer tuning.
  • Cost Savings: Eliminate or significantly reduce your travel expenses because training sessions are offered at a location near you (or even at your location).
  • Schedule: Training sessions can be easily scheduled months in advance. Get specific details regarding class locations, information on discounts, or having a dedicated training session at your company site by contacting us. Or, register for a class online.
Additional information
  • Classes will be canceled if minimum registration of 6 students is not met two weeks prior to the class dates.
  • Credit card orders are authorized but not charged until the class is confirmed.


  • Once a class is confirmed, any student wishing to cancel must provide written notice to us-training(ATMARK) at least 14 days prior to the class date or be subject to a cancelation fee up to 100% of the registration price.
