REI TALAN Telephone Line Analyzer

REI TALAN Telephone Line AnalyzerIt is a multifunctional digital telephone line testing and analysis tool that is compatible with analog signals. Very suitable for detecting QIE listeners in overlapping circuits, detecting electronic circuit overlap points and tracking circuit positioning electronic QIE listening devices. It is also a portable multifunctional tool for the communication department to repair, maintain, inspect, repair, and test digital telephone lines (including analog).

Features: The machine is small in size, light in weight, easy to carry, simple to operate, comprehensive in functions, and highly practical.

Digital demodulation function:

Equipped with digital decoding function, it is effective for about 80% of the world's digital telephone systems. The demodulation system can also be upgraded, so it can adapt to new telephone systems. The inspection of digital demodulation system is based on the principle that when a sound signal is detected on the line when audio should not be transmitted, we may determine that there is a QIE listener on the line.

Frequency domain display:

Similar to time-domain display but using different techniques. If the QIE listener is online, this device can easily identify these impedance abnormal lines through frequency domain display. The frequency domain display system can be used for testing different line pairs and comparing with historical test data.

Nonlinear node detection of the line:

DPA-7000 contains a non-linear node detection system that can check if electronic devices are connected to the line. This is one of the fastest and most powerful functions of the instrument to check for electronic devices on the circuit.

Digital multimeter detection:

DPA-7000 includes some basic multimeter testing functions. Such as voltage, current, capacitance, and resistance.

High gain audio amplifier and built-in audio oscilloscope:

The DPA-7000 includes a high gain audio amplifier, suitable for a frequency range of 20Hz-20KHz, with a maximum system gain of 80dB.

The DC bias generator (± 80VDC) can supply power to electronic devices.

RF analysis and detection:

The DPA-7000 has spectral analysis capabilities and can display detailed spectral information up to 85MHz. At the same time, it can also display the time-domain display of amplitude modulation (AM) and frequency modulation (FM) signals.

Broadband RF inspection function:

Can detect RF signals up to 8GHz. Display the variation of RF level over time in a chart format during use to locate the position of the transmitter.

Rich database system testing:

DPA-7000 has the function of storing all test data in a database structure, which facilitates our future analysis and comparison by managing and storing this data.

Harmonic positioning probe:

The DPA-7000 includes a harmonic positioning probe for checking the circuit, which can also be used as a harmonic receiver to alert users of changes in distance from electronic devices on the same circuit during positioning. This function allows users to not only detect the line, but also determine the specific location of electronic devices such as qie listeners on the line.

Automatic transformation matrix:

This function is used to analyze digital and analog telephone systems and lines for the presence of listener threats. This instrument is capable of conducting multiple tests to check for the presence of QIE listeners on communication lines, and includes an automatic switching matrix to test all paired combinations. For example, if a line contains 8 lines, there are 28 pairing combinations that need to be tested (8 × 7/2=28), which can automatically test all pairs and store the test data for analysis and comparison.
