signal analyzer

Digital eavesdropping and surveillance devices are commonly available for only a few hundred dollars, and may be easily built out of spread spectrum cordless telephones.

The Chinese, French, and United States government have all been using such devices for years. Dozens of these digital devices have been found in corporate offices, vehicles, and executives homes. These devices are being hidden inside other electronic devices such as computers, televisions, and copy machines.

The detection of a digital device becomes very difficult unless the equipment being inspected is opened and physically searched. These devices often operate with sub-milliwatt power levels, with a signal bandwidth often in excess of 1 MHz.

A Vector Signal Analyser (or VSA) is an instrument which allows modulation analysis of modern digital signals. The instrument is similar to that of an oscilloscope, however; the VSA allow the additional analysis of both the In-phase (I) and Quadrature-phase (Q) components of a signal. Modern eavesdropping devices which utilize vector modulation techniques often may only be identified by examining the I/Q components of a electromagnetic anomaly.

Components emitted by AM, FM, BPQSK, QSK, QAM, Pulse, and other modulations types are easily identified and evaluated. This will identify all but the most exotic digital eavesdropping devices. High bandwidth eavesdropping devices would be detected by the use of compressive or Bragg Cell receivers.

A VSA typically requires a dual I/Q signal input, which is generally only available on specialized radios (Rockwell, Condor, MACOM, or Watkins-Johnson), or modern spectrum analysers (such as the HP 71910A/P). The signal is then passed to the VSA which combines the signals into a complex quantum signal which exists only in the digital domain.

Complex signals analysis algorithms are then applied to the incoming signal to extract the modulation parameters. This will then permit the demodulation of most suspect signals.

Temperature Resistant IR Gas Sensor for CO2 and H2O

2010-01-02T05:01:00.000-08:00

Designing a high temperature resistant IR-gas sensor for CO2 and water vapor one has to consider the differences in the specific absorbances, spacings between the heated parts and optics/electronics, emission spectrum of cost-saving radiators and high humidity in the measuring gas. Using HITRAN database a sensor model was developed. Water vapor can be measured selectively at 1.85 μm with a chamber length of 20 cm. So CO2 has to be measured at low wavelengths too. In the range of 2.7 μm CO2 absorbs sufficiently but a water absorption is to be considered. The model shows that the CO2 absorption reaches a maximum in the range from 2.7 μm to 2.75 μm with a decreasing water absorption with increasing wavelengths. After finishing the sensor the model was checked with the actual filter curves. The results show a good analogy between model data and measurements and the benefit of modeling in the design of IR-gas sensors. The analyze of cross sensitivity shows strong overlapping bands and a multiplicative influence of water absorption to the CO2 signal. After correction of the absorption signal of 2.7 μm-channel with the absorption signal of the 1.85 μm-channel the cross sensitivity to water vapor was limited to <3% of CO2 measuring range.

Miniature Alcohol Breath Analyzer

2009-11-07T05:19:00.000-08:00

Road accidents all over the world are perhaps one of the major causes of death and injuries. Accidents are always unfortunate but it is even more worrisome when their cause is something that can very well be avoided like consumption of alcohol during driving. Everyone knows about it but a very few obey this. A breath analyzer is a device that helps keep in check to this problem by estimating BAC (blood alcohol concentration). If the BAC is more than the safe value or assigned limit it is advisable to avoid driving.

A Miniature Alcohol Breath Analyzer provides an excellent means to estimate the BAC anywhere and anytime. It is portable, speedy, compact and extremely light weight. It is a highly speedy device since it produces result immediately a person has blown into it. It is made up of special semiconductor technology which converts the content of breath alcohol into its equivalent in blood. A miniature alcohol breath analyzer does not actually test blood sample instead it calculates the concentration of alcohol in blood by examining just a breath of the person.
· A Miniature Alcohol Breath Analyzer consists of a monitor, thumb switch, a mouthpiece as input and an LCD display that lights up different colour lights to represent various levels of BAC. Due to its tiny size it comes across as a handy device that one can keep in pocket. It is reusable and can be used for both personal and public use. Traffic police officers use it very often to detect drunk drivers & remove them from the road.
· One of the major drawbacks of a Miniature Alcohol Breath Analyzer is that it not only identifies ethanol but also identifies compounds of similar structure, thus giving in a wrong value completely defying its purpose. Another problem is that these devices are extremely sensitive and hence give a false reading depending upon various environmental conditions like temperature, humidity etc. These are a few reasons why the result of these devices is not considered authentic in courts.

Because products should be controlled where they are being made and not in the laboratory. Off -line analysis requires time during which the process is running "BLIND". The benefit of real-time monitoring is tighter specification control. With this control, it is possible to adjust parameters such as temperature and pressure to achieve higher processing rates while maintaining razor-sharp control of product characteristics. The results are shorter cycles, higher throughput, greater equipment utilization, and all with the same manpower.
