Soft Function keys, built-in speakers and the classic rotary tuning dial help make OSCOR Blue easy to operate. Trace Analysis for Rapid Detection of Sophisticated Transmitters OSCOR Blue quickly identifies localized RF energy transmissions of all types of modulation, and has built in patented Trace Analysis. Reference and target traces are quickly captured, stored and compared for complete RF analysis. Zoom in on signals without interrupting sweeps, assuring no signals are missed. Signal lists are produced from captured traces as determined by manually set thresholds, allowing rapid comparison of signals from room to room. Waterfall zoom allows 5 MHz magnification without interruption to full spectrum capture Waterfall Trace Sequence Recorder The Waterfall Trace Sequence Recorder captures and records signal activity in a peak trace over time for historical analysis of transmissions down to 5 second intervals at 12.2 KHz resolution. The Zoom function magnifies the spectrum to 5 MHz without interrupting full spectrum capture (24 GHz or 8 GHz depending on model). Trace data is recorded in complete detailed resolution and can be zoomed and panned freely within the recorded spectrum but is not restricted to screen capture resolution. Signal Analysis, Classification, and Location While demodulating, OSCOR Blue provides Real-Time frequency display of up to 18 MHz. For example: the operator can view the realtime FM broadcast band while listening to a single signal. Signal Ranging is a feature of OSCOR Blue that shows the distance to an analog transmitter, quickly locating threatening signals. Digital signals can be easily located based on RSSI (Received Signal Strength Indicator) level change and near field locating function. An algorithm generates a signal list from captured trace data. Built-in Suite of Demodulators A built-in suite of audio and video demodulators aide in analyzing signals, including on-screen video demodulation.

4 OSCOR Blue Features Continued from page 3 OSCOR Blue delivers TSCM specialists real-time sweep speed and 24 GHz visibility in a single auto-switching antenna array. User friendly controls guide the user through a full palette of signal analysis features and functionality not found in any other spectrum analyzer. Production units of the NEW OSCOR Blue are expected to be available for shipment by year's end. Additional information including product specifications are available on the REI website at Contact REI for more information or to place an order at sales@reiusa.net REI RF Test Transmitters We are often asked by TSCM practitioners for suggestions on test transmitters for the purpose of creating test exercises to practice detecting illicit RF signals of varying types and modulation schemes (REI stresses the importance of hands-on exercises in our TSCM training courses). There are some obvious test devices such as wireless microphones, common baby monitors, and wireless cameras, all which are easily available (bargains can be found on ebay or common retailers). But we also have requests for devices to create more sophisticated signals such as digital/encrypted signals, frequency hopping or bust transmitters to really test one s skills for detecting and locating varying signal types using techniques other than just relying on analog demodulation. For obvious legal reasons, we do not recommend that illegal bugging devices are obtained for this legitimate testing purpose, however there are many commercially available, inexpensive devices that do not pose any legal issues which create sophisticated RF signals such as digital encrypted signals, frequency hopping, burst, etc. that can be used for test transmitters. Below are some examples of several types of easily obtainable test transmitters: Common Analog CW Signals: Common baby monitors, wireless microphones, FM transmitters, etc. provide inexpensive transmitters in various frequencies. These can be purchased inexpensively from common retailers. Video Signals: Wireless video cameras can be found on ebay for $30 - $100 in various frequency ranges (900 MHz, 1.2 GHz, 2.4 GHz, and 5.8 GHz). Digital Signals: We often asked for digital test transmitters mainly for the purpose of honing skills that do not rely on listening to a signal. This can easily be achieved by simply not using the audio function on your detection equipment, relying only on trace analysis and signal strength to detect and locate the source of any test transmitter (analog or digital). DECT: Cordless phones provide a very interesting burst signal (10 ms frame with 24 time slots per frame) using a multiplexed GFSK (Gaussian Frequency Shift Keying) modulation scheme. DECT is frequency agile across multiple channels anywhere from 1880 MHz to 1930 MHz depending on country allocation (some countries use 2010 MHz to 2025 MHz). Due to the bursting nature, it can take some modern digital spectrum analyzers some time before they actually detect a DECT signal (both the OSCOR 5000 and OSCOR Blue quickly detect DECT signals). DECT phones can be purchased from any large retail department stores (or online) for $20 to $50. Frequency Hopping /Spread Spectrum Transmitters: There are many DSS Digital Spread Spectrum and FHSS Frequency Hopping Spread Spectrum cordless phones in both the 2.4 GHz and 5.8 GHz ranges (note that in many instances a cordless phone may be advertised as 5.8 GHZ when in fact the handset transmits at 2.4 GHz while the base station transmits at 5.8 GHz). Additionally, common wireless access points (802.11) can 4 Continued on page 6

5 Importance of a NLJD ORION NON-LINEAR JUNCTION DETECTOR Bugging devices are often thought to be transmitters, but hardwired devices or devices that can be turned on and off remotely that do not emit an RF signal could be overlooked. The ORION Non-Linear Junction Detector is made to find these types of hidden electronic devices. The ORION NLJD detects hidden electronic devices regardless of whether the device is transmitting, hard wired, or even turned on at all. It transmits an RF signal and then listens for harmonic returns to detect the presence of electronics. When the transmitted signal encounters semi-conductor junctions (diodes, transistors, etc...), a signal is returned at harmonic frequency levels according to the characteristics of the junction, providing an indication of the presence of electronics. NLJD's also respond to corrosive junctions such as rust or oxidation Stronger 2nd Harmonic indicates electronics/semiconductor Stronger 3rd harmonic indicates corrosive junction and where dissimilar metals make contact. Corrosive junctions normally appear as false alarms and so it's important to ensure the NLJD can discriminate between true semiconductor junctions and corrosive junctions. The ORION provides excellent discrimination between the 2nd and 3rd harmonics, and utilizes automatic power control which reduces the transmit power to a level where a good distinction between the 2nd and 3rd harmonic levels is visible, making it easy to discriminate between true electronic junctions and false corrosive junctions. HOW ORION WORKS 1. ORION Transmits RF energy at a specific, known frequency (i.e. 915 MHz) 2. Detects (listens for) harmonic (2X, 3X, etc.) returns of known frequency (1830MHz, 2745MHz etc.) generated by electronic devices (i.e. diode, transistor, integrated circuit etc.) ORION s advantages include: Minimum Set-up Time, no cables or bulk transceiver units to carry Light weight, balanced ergonomic design for ease of use High Transmit power for rapidly searching a large area Circularly Polarized Antenna reduces search time and improves reliability Dual Harmonic with Discrimination Algorithms Minimizes False Alarms Standard type camcorder battery with long use time and quick charge function Wireless Headphones and Graphic Display for simultaneous Audio & Visual Information The ORION detects electronics, even when they re not turned on.
