Professional Telephone Line Analyzer
Search Query
The NEW Telephone and Line Analyzer provides a complete integrated suite of tools to analyze, inspect, and test digital telephone lines (and other wiring) for taps and other eavesdropping devices.

The Telephone and Line Analyzer incorporates several types of telephone line tests including common tests such as voltage, current, resistance, and capacitance tests, as well as NEW technology such as line NLJD, FDR Frequency Domain Reflectometry, and Digital Demodulation into a single piece of equipment. Additionally, the Telephone and Line Analyzer utilizes an automatic internal pair switching matrix to automatically perform tests on all pair combinations. The ability to perform several different tests allows the user to compare the results of multiple tests on multiple phone lines, quickly identifying any potentially threatening anomalies.

The Telephone and Line Analyzer represents a new breakthrough in telephone line testing. There currently is no other product available with the same capabilities.

Digital Demodulation
Includes digital decoding capabilities for approximately 80% of the world’s digital phone systems. Demodulation codecs are upgradable as new phone systems become available. Digital Demodulation confirms that a line on a digital phone system is not passing audio when it should not.

Frequency Domain Reflectometer (FDR)
Similar to a TDR (Time Domain Reflectometer) but based on a different technical approach, the systems 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 or historical comparison.

Non-Linear Junction Detection (NLJD) on a Line
The system 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 Multimeter Tests
The system includes basic multimeter 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
The system includes a High Gain Audio Amplifier (20Hz to 20KHz) 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
The  system includes a Spectrum Analyzer 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. The system 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. (Broadband RF levels not shown)

Harmonic Locator Probe (HLP)
The system 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.
