Delta X. User Manual70the function is described for each further input. The Signals table and the Waterfall are cleared eachtime the Zero button is pressed.The "Full Range"a button sets the recommended span of the spectrum graphs for the Probe mode: 0 –10 MHz. This range is selected as the most probable for bugging. Nevertheless a wider span can beselected manually. Please note that despite the spectrum graphs display, the span starting from 0means the actual measured range begins at 40 kHz or 100 kHz, depending on the system's version.Like in all other modes double clicking on a signal in the Signals table performs tuning it in. Thespectrum graphs adjust automatically to show the clicked signal fully. If the Detector is in the Signalmode it will be assigned to the clicked signal. A single click tunes in a signal without adjusting thespectrum graphs.Clicking on the Spectrogram allows tuning in the desired frequency.The Persistence view of the Spectrogram, when activated, allows the user to distinguish between thecontinuous and non-constant signals.Infrared (IR)Since infrared rays have a directed nature, the potential IR bug will be directed to the place of thesignal's reception. The most likely direction will be the outer area near the building or a remote part ofthe room. The detection should be performed inside the room and in the windows' area, with theMultifunction Probe pointed to the interior of the room, window frames and the area near the frames.The detection distance of the probe's IR sensor depends on the transmitter's power and can be 1-5meters, on the condition of being pointed to the source.Algorithm1. Connect the "SWITCHER OUT" to the INPUT with the help of the supplied jumper cable2. Connect the Multifunction Probe to the PROBE with the help of the supplied coax cable3. Select the IR input on the probe4. Select the Probe mode in the Delta X software5. Cover (close) the probe's IR sensor and press the Zero button. Keep the sensor covered for fewseconds6. Create a source of sound in the room to activate any potential bugging devices7. Point the probe's IR sensor to the place of possible bugging (for example, from outside thewindow to the interior and frames)8. If an infrared signal is detected, it will be automatically inserted into the Signals table.9. In case of finding a signal, rotate the probe in different directions in order to find the strongestlevel, which will mean that the sensor is directed to the transmitter. Move the probe closer tothe supposed source while observing the change of level. Try to find the place with the highestdanger level. The Audio alarm function will change the intensity of sound correspondingly. Inthe place where the strongest level is found start a physical inspection. If the entire areaproduces a low to average level of danger, and there is no one place with a strong signal, it maymean just the presence of interference.10. Repeat the test near other windows and parts of the room |
