TALAN 3.0 DPA-7000 Telephone and Line Analyser

  • Represents a new state-of-the-art capability to rapidly and reliably detect and locate illicit wire taps on both digital and analogue telephone systems.
  • Provides the capability to perform multiple tests to analyse communication lines for eavesdropping devices.
  • Includes a built-in automatic switching matrix for testing all pair combinations. For example, if a cable has 8 conductors, there are 28 combinations of pairs to test.
  • Can automatically switch through all combinations, performing test functions and storing data for comparison.

 

Digital Demodulation:

  • Includes digital decoding capabilities for approximately 80% of the world’s digital phone systems.  Demodulation code CS is upgradable as new phone systems become available.
  • The Digital Demodulation function provides the ability to determine if a digital phone line is passing audio when it should not.
  • Frequency Domain Reflect-o-meter (FDR), Similar to a TDR (Time Domain Reflectometer), but based on a different technical approach, the TALAN’s FDR can “shoot” a line for impedance anomalies indicating a tap on the wire. The FDR also has the ability to plot multiple FDR traces on the same display for comparison of multiple pairs for historical comparison.  Analyse digital and analogue phone systems and wires for eavesdropping threats.

 

Telephone and Line Analyser:

  • Combines New Technology into a Suite of Telephone Tests including an Automatic Switching Matrix.
  • Provides the capability to perform multiple tests to analyse communication lines for eavesdropping devices.
  • Includes a built-in automatic switching matrix for testing all pair combinations. For example, if a cable has 8 conductors, there are 28 combinations of pairs to test. The TALAN can automatically switch through all combinations, performing test functions and storing data for comparison.


Non-Linear Junction Detection (NLJD) on a line:

  • Includes a NLJD test to detect electronics connected to an isolated line.  This is one of the most powerful tests for quickly determining whether or not there are additional electronics attached to a wire. 

 

Digital Multi-meter Tests:

 The TALAN includes basic millimeter tests such as:

  • Voltage
  • Current
  • Capacitance & Resistance

The automatic switching matrix allows the user to quickly measure and display results for all pair combinations, easily identifying any anomalies.

 

High Gain Audio Amplifier and Built-in Audio Oscilloscope

  • Includes a High Gain Audio Amplifier (20Hz to20KHz) with up to 80dB of total system gain (voice band).  A DC Bias Voltage Generator (±80VDC) is also provided to power attached electronics.

 

RF Analysis and Detection

  • Includes a Spectrum Analyser that provides a detailed frequency spectrum display up to 85 MHz. This function also includes a time domain display to show the modulation for AM and FM signals.
  • Also includes a Broadband RF Probe to check free space RF energy up to 8GHz, graphing the RF level over time to identify the location of a transmitter.

 

Harmonic Locator Probe (HLP)

  • Includes a Harmonic Locator Probe (HLP) used for tracing wires.  The Harmonic Locator Probe also acts as a Harmonic Receiver, alerting the user as the tracer approaches electronics connected to a wire. This allows the user to not only trace a wire, but also determine the location of any electronics connected to the wire such as an eavesdropping device.

 

Multi-test Database System

  • Provides the ability to store test data for all testing functions in a database structure. This database provides the ability to organise and store results for future review or comparison. The display at the right shows the basic database structure keeping track of test data from multiple targets and locations.
