CMA-100 Countermeasures Amplifier for detection of surveillance devices, which are wired in a building

CMA-100 - countermeasures amplifier is a counter surveillance tool for detection of electronic devices, which are attached to the wiring of the building.

The contermeasures amplifier detects among others LAN and server systems, telephone wiring, AC power, and alarm wire. The device is equipped with sophisticated automatic gain control circuit function, which makes it unique in comparison to other devices of this type.

The device is extremely efficient. There are minimal distortions while monitoring large signals. Moreover, adjustable bias voltage is able activate devices that are voltage or sensitive to current.

The CMA-100 countermeasures amplifier is also equipped with AC/DC digital voltmeter, select-able audio filters, and a wide dynamic range.

The advantages of the Countermeasures Amplifier CMA-100 for detection of surveillance devices, which are wired in a building :

• Independence of the balanced input of 50K ohm, can withstand being attached to live power lines with voltages up to 250V, and provides up to 115dB of gain;
• Automatic Gain Control AGC that has 105 dB of control;
• Signals as large as 31V peak-peak can still be monitored with minimal distortions;
• Manual gain control may be set to 0, 25, 50, 75, or 100 dB;
• Positioning of filters to FLAT, LOW PASS, HIGH PASS, or BAND PASS.
