New Hand-Held ANDRE Quickly Detects Transmitters

07 Mar 2017 Research Electronics International

Research Electronics International is pleased to announce the ANDRE™ Advanced Near-field Detection Receiver, a hand-held broadband receiver that detects and assists in locating nearby RF, infrared, visible light, carrier current and other types of transmitters.

Advantages

The ANDRE detects signal activity in its vicinity and displays changes in signal strength over time, allowing users to quickly locate the source of transmissions. The ANDRE’s frequency counter provides quick frequency information of the strongest signal and outputs additional information to an automatic signal list generator.

Antenna probes included with the ANDRE can be used to sweep rooms and objects in search for known, unknown, illegal, disruptive, or interfering transmitters from 10 kHz to 6 GHz.

A 3.5-inch touch screen displays all of the operation controls and frequency activity. The frequency chart provides advantages over other RF detectors by showing rising and falling signal strength over time. Eight displayed time intervals can be selected ranging from 5 seconds to 24 hours. This helps identify pulsing signals and shows historical peaks, to ensure nothing will be missed. Manual and automatic threshold settings notify the user when a signal exceeds defined strength levels with haptic, audible, and visual alerts.

ANDRE Advanced Near-field Detection Receiver Feature DiagramThe ANDRE automatically recognizes connected probes and displays the appropriate frequency band on the time chart. When there are no probes attached, the ANDRE’s built-in visible light/IR probe is active.

The ANDRE also has a built-in AM audio demodulator that allows users to listen to signals. Ten second audio clips can be recorded for reporting.

A built-in frequency counter registers the strongest signal and displays the frequency. Output from the frequency counter can automatically generate a signal list with additional details such as received signal strength, attenuation and gain settings, and information about the communication band classification. Band identification will help classify detected signals based on the FCC frequency allocation the signal falls within.

As the signal list builds, stronger signals rise to the top of the list and weaker signals fall within the list. The signal list displays the frequency, date/time and the option to designate the signal as Friendly; Threat; or Unknown. The ANDRE also has the option to capture and store screen shots of any of the screens and audio files. A USB port and cable provides the means for transferring files and recharging batteries in the unit.

Applications

Access to eavesdropping and electronic bugging devices is becoming easier and more affordable. Broadband receivers, like the ANDRE, provide mobile RF search capability to help locate these and other transmitters quickly and discretely.

RF investigators will find the ANDRE a valuable asset and affordably priced to complement advanced analysis equipment, like the OSCOR spectrum analyzer. It can also be used independently to acquire quick, non-alerting RF detection and location.

In addition, the ANDRE can be used by wireless industry developers, RF hobbyists, and educational institutions for RF research and development. Commercial and corporate applications include performing site surveys, installing and maintaining RF systems, and emissions detection of illicit transmitters.

The ANDRE replaces the discontinued CPM-700 Broadband detector. REI will continue to support the CPM-700 with parts and service as long as parts supplies last.

  • “I very much look forward to continuing my personal support to DSEI. It provides an excellent opportunity to explore the development of airpower capability, through engagement with the widest range of industry and international partners.”
    Air Chief Marshal Sir Stephen Hillier KCB CBE DFC MA RAF Chief of the Air Staff
    Royal Air Force
  • “I much look forward to DSEI 17. We intend to build on the very positive experience of DSEI 15 as we construct the partnerships we need to deal with the complexity of the future operating environment”
    General Sir Nicholas Carter KCB CBE DSO ADC Gen Chief of the General Staff
    British Army
  • "DSEI 2015 was the ideal occasion for the Royal Navy to demonstrate its ambition to lead and win through technological innovation. The opportunity to meet with so many partners from academia, industry and overseas at DSEI is, as always, a really useful component of our engagement with the vital partners through whom we seek to deliver this innovation."
    Admiral Sir Philip Jones KCB ADC, The First Sea Lord and Chief of Naval Staff
    Royal Navy
  • "DSEI 17 will offer Joint Forces Command the opportunity to report on our plans for the future, in particular on operationalising our Warfare In The Information Age concept. I am looking forward to it."
    General Sir Chris Deverell Commander Joint Forces Command
  • "DSEI is a highlight within the defence calendar, I use it to find out what the most recent developments are in every technological area affecting for defence. Without DSEI I fear this sort of interaction, information exchange and knowledge of developments across all domains would be lost. DSEI is an invaluable international biannual event .”
    Rt Hon Dr Julian Lewis MP, Chairman, House of Commons Defence Select Committee
    UK Parliament
  • “DSEI is a fantastic showcase for defence companies where international buyers, sellers, developers, thinkers, educators and the trainers can all get together. The UK defence industry is looking to recruit more engineers, scientists and developers into 200,000 jobs and up to 10,000 apprentices within UK defence companies. DSEI is an excellent tool to highlight the challenges the industry face as well as showcase its capabilities domestically and overseas.”
    James Gray MP, House of Commons Defence Committee
