RF Detection Equipment Comparison Cartoon

Software Defined Radios (SDR) are becoming more common to use when looking for rogue RF transmissions in certain environments. They may appear to be less expensive simply because there are many tuner modules on the market that provide Spectrum Analyzer capability for very low cost, and there are various suppliers of software and hardware to mix and match all sorts of system combinations. However, total cost of software, antennas probes, cables, software defined receivers, a laptop, etc., can get expensive.

FOR IMMEDIATE RELEASE

Algood, Tennessee, U.S.A. – July 6, 2015 – Research Electronics International (REI) has introduced a new Non-Linear Junction Detector (NLJD)   – the ORION 2.4 HX. The new ORION 2.4 HX compliments the standard ORION 2.4, introduced in 2013, with several distinguishing features including a 3.3W model and a higher 6.6W transmit power model, both with built in touch screen display.

The above illustration is a composite screen shot taken from an OSCOR Green Spectrum Analyzer, showing traces from 2 NLJDs. The purple trace is a commercially available NLJD transmitting a continuous wave analog signal at 2.41 GHz. The yellow trace is an ORION 2.4 broadband digital spread spectrum signal at the same frequency. The spread spectrum signal of the ORION 2.4 is almost 400 times wider than the CW signal. The spread spectrum signal puts more energy on an object at a given time.

 

In the late 80s and early 90s, the bag phone was developed as a portable communication device, but when the next generation digital cell phone came out, the bag phone and other analog variants soon became history. Digital signal processing offered so many benefits to signal delivery, there was really no comparison. Modern digital modulation can provide higher quality signal purity with much lower noise interference. Today, practically everything is digital.

FOR IMMEDIATE RELEASE

Algood, Tennessee, USA – August 22nd, 2013 – Surreptitious electronics are becoming smaller and harder to detect, which can present serious problems for security professionals everywhere. The new ORION™ 2.4 Non-Linear Junction Detector (NLJD) from REI provides better sensitivity for detecting and locating smaller more advanced semiconductor circuitry, even when the target device is turned off.
