Frequency counter and bug hunter

The Aceco frequency counters can be used as a measurement device as well as a bug hunter. They display the frequency of the direct fed in or strongest received signal. Hidden transmitters are easily found this way (bug hunter). The frequency counters are not designed to repeat the recieved signals. The counters find analogue signals, the SC-1 even digital signals.

The Aceco near field recievers adjust themselves automatically (or remotely) to the strongest signal and repeat it. In doing so only FM signals will be decoded.

The Aceco FC-6002Mk2 is specifically designed as a bug hunter with wide frequency range.

The Aceco frequency counter come complete with rechargeable batteries, wall charger (230V) and antenna (BNC jack) in a solid metal case. The counters are very sensitive, when using the supplied telescopic antenna a range of about 20m can be achieved (tested with a FC-2002 sensing a normal 2W handheld with rubber duck antenna). Operating time approx. 6 hrs with fully charged batteries.

Concerning the frequency precisison the manufacturer writes:

The timebase of our counters is less than 1 PPM at room temperature. Before shipping all the counters are fully calibrated with an external frequency standard input (HP 8648C Signal Generator).

The stability specifications are as follows:
a. Initial Accuracy at Room Temperature: ±1PPM.
b. Frequency Stability vs. Temperature (-10 to 60°C): ±5PPM in the entire range from -10 to +60°C.
c. Frequency Stability vs. Aging/Year: ±2PPM.

Aceco FC-5002

Aceco FC-5002 Near Field ReceiverThe FC-5002 is a near field receiver which intercepts automatically and very fast any FM signal between 30 and 900MHz in the vicinity. Works like a scanner, but much faster (less then one second typically).

Ideal for personal security, interception of voice traffic at sport events, testing other radios etc.

Aceco FC-6002 MK2

Aceco FC-6002Mk2The FC-6002 Mk2 is a portable RF tracer and bug hunter. It covers the frequency from 1 MHz to 6000MHz. Used to find hidden transmitters like GSM and DECT phones, audio and video spy transmitters at 2.4GHz and many other RF emitting devices in the usual frequency range.

The receiver detects digital (GSM, DECT) as well as analog signals. The detection distance is about 1 to 3m, depending on transmit power. The alarm is either by a signal tone, which frequency changes relative to the received signal strenght (ie.e distance), or by a silent vibration alarm. Furtehr a 5 digit LED bar graph is shown. This silent alarm allows to find the transmitter without alerting the intruder.

The FC-6002 Mk2 is equipped with internal rechargeable batteries and fits in any shirt pocket. With the small size and ease of use it becomes very easy to find hidden wireless bugs or stuck transmitters in a conference or hotel room or vehicle.

SC-1 Frequenzzähler für digitale und analoge Signale

Aceco SC-1In contrast to the devices show nabove the SC-1 also detects digital, pulsed signals like DECT- or GSM-phones, WiFI (Wireless LAN) or other digital signals. NB: This device just shows the frequency of the detected signals, actual decoding is not possible.

RF Explorer spectrum analyzer with USB port RF Explorer is a portable spectrum analyzer. The LC display with background light shows a section of the radio spectrum and the receivable signals. Signal strength is shown in dBm or dBµV. This way you can see available signals on chosen frequency range at a glance. This makes the RF Explorer a very useful measurement instrument as well a fast working bug hunter to find hidden transmitters easily.

The RF Explorer has a frequency range from 15 to 2700 Mhz covering all important radio ranges that are used for surveillance cameras, mini transmitters, WLAN, emergency services radio and many others. Two different antenna inputs for various frequency ranges allow for the use of specially adapted antennas that make the RF Explorer even more sensitive. Minimal sensitivity of the spectrum analyzer is -115dBm. A marker on the LC display indicates the level of the strongest signal automatically.

Center frequency and displayed spectrum are easily adjusted in the menu, as well which antenna input to use. The display can memorize and display received maximum values. This means you can leave the receiver unattended for a while and check later if a signal was received. A special Wifi mode allows for detailed monitoring of channels on 2.4Ghz WLAN.

The USB port of the RF Explorer is used to charge the internal Li-Ion battery (1000mAh) and to transfer data to a PC or MAC computer. With the help of freely available software the received signal spectrum can be displayed on the computer and saved for documentary purposes. The Software is open source, the USB port transfer protocol is documented, too. This makes the RF Explorer very open and perfect for hackers and hobbyists, who want to implement their own ideas. Also, firmware updates are applied via USB. The USB-Cable is not included.

SMA Male/Female Adaptor

All RF connectors wear with use. The RF Explorer SMA ports are subject to minimal wear each time the connector interface is coupled and de-coupled with an antenna, a SMA cable, an attenuator or a RF device of any kind. If you repeat plug/unplug operations over the RF Explorer SMA port hundreds of times, the SMA port may underperform over time and exhibit undesired attenuation.

To protect the SMA port for frequent plug/unplug operations, you can use this adaptor and keep it directly attached to the RF Explorer port. Then you plug/unplug other RF devices into this adaptor, not the original SMA port. After hundreds of operations, if the adaptor wear and show attenuation or reliability problems, you can just replace it by a new one and always keep your original RF Explorer SMA port intact.
