The 2669B is an Amplifier from Bruel & Kjaer. Amplify RF and Microwave signals to measure, test, and design circuits. Applications include radio communications, cellphones, EMI testing, and much more.
Features:
Full electromagnetic compatibility (EMC)
Detachable, thin cable for easy installation
Compact LEMO connector at preamplifier
Patented charge-injection calibration technique for on-site calibration of the whole measuring channel including the microphone
Wide dynamic range
Very low inherent noise, high input impedance
Low output impedance and high output current allows use with long extension cables
Wide working temperature range
The preamplifier has a very high input impedance presenting virtually no load to the microphone. The high output voltage together with an extremely low inherent noise level gives a wide dynamic range.1/2-inch Microphone Preamplifier Type 2669 is a Falcon Range product for making precision acoustic measurements with Brüel & Kjær’s wide range of condenser microphones. You can connect 1/2-inch microphones directly and 1-inch, 1/4-inch and 1/8-inch types using adapters.
The preamplifier, cable and its connectors all fulfil EMC requirements.
You can verify the condition of the microphone, preamplifier and cable on-site using its patented charge injection calibration technique.
The preamplifier’s low output impedance allows the use of long extension cables without problems.
