• Digital Demodulation Function Equipped with digital decoding functionality, if an audio signal is detected on a line that should not be transmitting audio, it can be determined that there is an eavesdropping device on the line.

• Frequency Domain Display This device easily identifies these impedance abnormal lines through frequency domain display. The frequency domain display system can be used to test different wire pairs and compare with historical test data.• High Gain Audio Amplifier and Audio Oscilloscope Includes a high gain audio amplifier suitable for frequencies ranging from 20Hz to 20KHz, with a maximum system gain of up to 80dB. The DC bias generator (±80VDC) can power electronic devices.• RF Analysis and Detection Features spectrum analysis capability, providing detailed spectrum information up to 85MHz. It can also display the time-domain graphs of amplitude modulation (AM) and frequency modulation (FM) signals.• Non-Linear Junction Detection on Lines Includes a non-linear junction detection system to check for electronic devices connected to the line. This is one of the quickest and most powerful functions of the instrument to check for electronic devices on the line.• Digital Multimeter Testing Includes basic multimeter testing functions such as voltage, current, capacitance, and resistance.• Broadband RF Inspection Function Capable of detecting RF signals up to 8GHz. During use, it displays the RF level over time in a graph, helping to locate the position of the transmitter.• Harmonic Locator Probe This probe can also be used as a harmonic receiver to alert the user to changes in distance to electronic devices on the line during localization. It can also pinpoint the exact location of electronic devices such as eavesdropping devices on the line.

Measured Shielding Range of 2-10 Meters The shielding range for Apple phones is approximately 2-3 meters, while Android phones have a shielding range of 5-10 meters.

Wireless Remote Control Equipped with a wireless sensor remote control, it can remotely turn the device on and off, adjust the frequency of the shielder, with a sensing range of 1-10 meters.

When digital devices such as mobile phones record, these noises are recorded together with the sound of normal conversation into the digital device, making the recorded audio invalid. The audio information in the recorded video also has the same interference effect. Since the noise with ultrasonic noise is generated randomly and cannot be restored, the audio after interference can not be restored, so as to ensure that the original information is not leaked and transmitted.

Measured Shielding Range of 1-5 Meters When a microphone is directly facing the shielder, the effective distance varies with different brands of smartphones and recording pens.

Multi-Angle Adjustable Independent Switches The device can independently control the switches of the four-sided combined emission terminals to meet the needs of different scenarios.

The 66 recording shield product produces suppressive interference to the speech signal through random acoustic signals, so that the digital recording equipment only has noise information, but can not distinguish the voice signal. Through randomly generated sequences, the original information cannot be restored from the recorded signal, thus ensuring the security of voice messages.
