30MHz-6.5GHz High Sensitivity Signal Level Meter Radio Detector Features: Operating frequency: 30MHz-6.5GHz 2. Power supply: DC-9V (laminated battery, commercially available) 3. Working current: less than 2mA The built-in battery can work continuously for more than 240 hours, when the amplitude adjustment knob clockwise rotation in the end, the pointer does not need to replace the battery when the full table. 5. The test is completed, it is best to close the amplitude adjustment knob is used to disconnect the internal power supply to avoid power is still power. First, the product advantages: 1: The appearance of simple and efficient, nice 2: frequency bandwidth, high sensitivity, 30MHz-6500MHz can be tested (the full list can be transferred without emission) 3: Pointer amplitude can be adjusted! (To protect the header) 4: Built-in automatic damping function, which is buffering function to prevent excessive damage to the hands swing 5: small size, easy to carry! Size: 90 * 115 * 55mm (not including the antenna portion raised) 6: Test Sensitivity: 1,10-50mW transmitter distance of about 10-50cm 2,50mW-200mW transmitter, 50cm-1 range meter. 3,300mW-1W transmitter from 1-5 meters. 4,1W-5w about 5-20 meters. Second, use: Before using the "adjustments" knob on the front panel clockwise rotation, turn on the power to hear the sound of Cartagena, clockwise rotation adjustment field strength meter sensitivity, handheld walkie-talkie from the field strength meter is about 2-5 meters, not too close ??? Signal Strength Meter in order to avoid too strong to burn! Then press the PTT walkie-talkie button, so the intercom into the launch state, then Level Meter pointer should signal indication, the stronger the signal indicating the greater! Amplitude adjustment: as a field strength meter pointer exceeds the maximum range, adjustable "amplitude modulation" so that pointer to the appropriate location, Three-antenna maximum gain point test method. 1. In order to facilitate the quick change frequencies, should be used with a keyboard to manually set the frequency walkie-talkie. 2. Link good walkie-talkie and antenna feeder, place the antenna close to the field strength meter (distance depending on the environment), as far as possible be placed in a vertical radiation angle of the antenna, and the antenna same plan the best way. 3. Set a good walkie-talkie frequency, press the launch button, observe the meter reading, and register this frequency meter readings. Then put the intercom set to other frequencies, so that the intercom again into the launch state, observe the meter reading .... and then compare the readings for each frequency! You can know the best frequency antenna under test / section! IV. Anti-anti-eavesdropping equipment photographed anti-anti-anti-wiretapping the phone listening device to detect wireless signals 1. Current radio and television stations reported on within the hotel wireless wiretap and wireless burglary reported information like that is candid, making travel frequently stay in hotels for a friend at a loss, with the radio wave detector can be easy to get. For pinhole camera and mobile phone signal detection is very effective, pinhole cameras and listening devices in the signal is a continuous signal, but the cell phone signal is not continuous signal, judgment is also very good judgment. 2. The criminals often in hotels, restaurants, bathing centers, the locker room, public toilets, swimming pools, overpasses, shopping malls escalators, bus, snack bar near floor windows, offices, meeting rooms, business negotiation, residential interior , next to the student proctor, KTV, car, bathroom, ATM automatic teller machines, etc. are likely to be installed in disguised form of miniature pinhole cameras, listening devices and other wirelessly transmit signals.This detector is completely all other between the 30MHz-6500MHz capable of detecting current popular CDMA 4G 3G 2G and 1.2GHz, 2.4GHz, 5.8GHz, WIFI, Bluetooth, GSM mobile phone signal, FM, wireless microphone, eavesdropping, etc. and All radio wave signals. Especially can detect whether the phone is listening (whether undue transmit signals to determine when the phone is in standby) detection distances up to 20 meters. No matter what form of camouflage can not escape the eyes of this detector 3. Common disguised form of wireless transmission used: Too many pen-shaped bug or videotaping, a frame-shaped hook camouflage, camouflage socket, cans camouflage, camouflage cigarette, ashtray camouflage, camouflage murals, power switch camouflage, camouflage form , no longer listed, no matter what form of camouflage, as long as it emits a radio wave signal, we can detect.
