When you take the best features of a portable, handheld broadband RF detector (size, portability, utility) and combine them with the analysis capability of a spectrum analyzer, you get the MESA® – Mobility Enhanced Spectrum Analyzer. The MESA® is a compact, full-featured portable spectrum analyzer with physical search capability similar to a broadband receiver.
The first thing you may notice about the MESA® is how easy it is to navigate. Once you get a feel for the menus, icons, buttons and the main screen controls on the 7” capacitive touch screen, it may seem like you have it all figured out, but really, you’ve only begun to scratch the surface. Beneath the user friendly display is a powerful palette of tools and functions to help identify and locate signals.
MESA® is available in a Basic and Deluxe package (see the Accessories comparison chart). The MESA® Deluxe includes six RF antennas. The Fixed Dipole and Whip Antenna, are uniquely designed hybrid antennas that include a circular dipole for a higher frequency, and a longer mass antenna for low-frequency signals. The Down Converter antenna is a directional antenna with a frequency range from 500MHz to 12GHz. Other antennas include a Locator Probe, VLF probe, and low-frequency directional antenna. The QMA antenna input allows for non-REI antennas to be connected.
MESA® also has a Multi-Carrier Probe (carrier current), Ultrasonic, IR/Visible light, Audio Transformer and Audio Leakage probe. MESA® automatically recognizes REI antennas and probes when connected and adjusts the frequency display.
Operation Modes – Spectrum Analysis
MESA®, like the OSCOR®, is a portable swept-tuned super heterodyne spectrum analyzer that sweeps to 6GHz (12GHz with the Down Converter antenna included in the Deluxe model), at a speed of >200GHz per second at 312.5 kHz resolution bandwidth.
The Resolution Bandwidth (RBW) auto-adjusts depending on the frequency span.
• The narrower the span the finer the resolution bandwidth
• The wider the span, the higher the sweep speed
MESA® displays a full range of frequency data including span, start and stop frequencies, dB, RBW, Peak/Average Trace, Persistence Trace (below 200MHz spans), raster waterfall, RSSI, Alerts, and signal lists.
A new patented Cached Peak feature, preserves and displays 312.5kHz and 39kHz resolution Cached Peak traces as the span is zoomed in to higher resolutions, enabling peaks obtained at previous resolution bandwidths to be seen.
SmartBars™ – Mobile Bands – WiFi/Bluetooth®
SmartBars™ is a new patented mode that quickly detects and locates RF energy by displaying a bar graph of new signals, or increased RF energy, compared to a reference trace from outside the target sweep area. SmartBars™ offers a Fast Scan and a Signal Resolution scan which creates a signal list of signals that exceed the user-defined threshold.
Watch this video for an overview of how SmartBars™ works.
Additional display modes include Mobile Bands displaying RF energy levels for multiple RF Bands (i.e. WiFi, GSM, etc.) on one screen. Each Band is customizable to user-defined spans. This mode is excellent for quickly searching for RF energy in specific spans.
WiFi and Bluetooth® modes display nearby WiFi access points and Bluetooth® devices, relative signal strength, and links to the Spectrum View to view it in live frequency trace mode.
The MESA® is a completely new product that complements REI’s existing RF products – ANDRE® and OSCOR®. With the complexity and sophistication of new threats, multiple RF detection tools are required. Here are some of MESA’S benefits:
• Easy to use spectrum analyzer in a handheld package with touch screen controls
• Portable: 5 x 8 x 2 inches; (12.7cm x 20.3cm x 5.08cm), 1.08kg
• Sweep speed: >200GHz/second at 312.5kHz resolution; 30GHz/second at 39kHz resolution
• Quiet, flat noise floor with no internal spurious signals
• Quick to deploy and easy to use and walk around with, for fast effective site surveys.
• Patented SmartBars™ function to quickly and easily identify new signals using inside to outside comparison.
• Mobile Bands function displays RF energy level in user-defined spans
• Built in ITU database provides additional band information on detected signals
This fast, hand-held spectrum analyzer has operational capabilities suited for detecting illegal, disruptive, rogue transmissions across a wide frequency range and is ideal for:
• Communication systems site surveys
• RF emissions analysis
• Wireless service providers and installers
• Investigations of corrupt RF spectrum misuse
• Security surveys for eavesdropping detection
When COVID brought travel to a halt in early 2020, REI had to cancel many of its training courses, but customer demand for product and TSCM information never diminished. Since change and adaptation became the theme for 2020, REI instructors began searching for different ways to stay connected and at least try to satisfy some of the appetite for information.
REI customer feedback has always concluded that virtual training will never achieve the standard of in-person training for a number of reasons (hands-on access to equipment, live exercises, personal instruction, and networking). Under the present circumstances; however, virtual webinars can certainly provide value in the absence of in-person training.
REI instructors developed a series of free online Zoom Seminars to provide an overview of products and popular TSCM topics which includes ANDRE; OSCOR; TALAN; ORION; GPS Tracking; Basic Telephony; Introduction to VoIP, with more to come. Each seminar is approximately 1 hour long with Q&A at the end. The format is informal and interaction is encouraged. Capacity is limited to ensure optimal participation, so early registration is recommended.
In-person training courses have resumed, but REI plans to continue offering the online seminars. Schedule and registration information for online seminars and REI Training courses are available through the links below.
The REI Training Center recently added a new Level 2 course for REI’s newest product: MESA® – Mobility Enhanced Spectrum Analyzer.
The 5-day MESA® course will review radio frequency energy fundamentals. This module will further explore the basic characteristics of radio frequency (RF) energy and how it behaves in a normal environment. The purpose of this segment will be to build on the student’s knowledge of RF energy as it relates to spectrum analyzers.
Trainees will be introduced to the MESA by examining its technical specifications, operational features and function compared to other REI RF products – ANDRE and OSCOR. Modes and features to be examined in hands-on exercises include Spectrum Mode, the patented SmartBars™, Mobile Bands, Wi-Fi and Bluetooth®.
The Countermeasures Core Concepts course is a prerequisite to the MESA Course. Schedule and registration for the MESA® training course is available here.
7 Ways to Protect Your Equipment from Electrostatic Discharge (ESD).
The weather is changing and cooler temperatures mean short days, cozy sweaters, and static electricity. Colder, drier air outside causes us to turn on heat indoors further lowering humidity, which adds to the conditions that promote static electricity. Today’s electronic components and assemblies tend to be smaller more efficient, and also more delicate and sensitive to ESD and can be affected by even the smallest unseen, unfelt electrical charge. ESD can cause erratic operation, shortened electronic life expectancy, or catastrophic failure.
At REI our production teams take extra precautions to prevent static electricity, and here are a few tips to keep your products functioning properly.
- Review the product user manual.
- Prep your work area – use a grounding work surface or mat when possible.
- Check the humidity levels of the environment you’re sweeping in, take extra ESD precautions when working in a dry environment.
- Transport and store the equipment in the original manufacturer’s case to prevent accidental ESD events.
- To discharge built up ESD on your person, touch a piece of metal before handling any electronic equipment.
- Practice social distancing – keep charged materials about a foot from your devices. Be aware of how close you’re keeping plastic, foam, scotch tape, and other materials that can build up a charge.
- Try not to overdrive your equipment inputs.
Taking precautions for ESD can save time in your sweeps and money.
REI and parent company HEICO completed acquisition of 2 partner companies in August, 2020: Transformational Security (“TS”) and Intelligent Devices (“ID”).
