Bruel & Kjaer Analyzer Type 2107 Product Details
Frequenzy Analyser
Type 2107 is an AC operated audio frequency analyzer of the constant percentage bandwidth type. It has been designed especially as a narrow band sound and vibration analyzer, but may be used for any kind of frequency analysis and distortion measurement with the frequency range 20 Hz - 20000 Hz. A built-in mechanical device enables automatic tuning from an external motor, e.g. the motor in one of the B & K Level Recorders. When used together with a B & K Level Recorder frequency amplitude diagrams can be recorded automatically. The analyzer can also be used as a linear amplifier and a vacuum tube voltmeter in the frequency range 2 Hz - 35000 Hz, It contains, furthermore, the internationally standardized weighting networks for sound level measurements and a 7-poled input socket for connection of a B & K Condenser Microphone or Preamplifier.
The instrument is supplied with the special B & K, R.M.S.-Average and Peak rectifier and meter circuits and facilities are provided for connection of external filters, for example the 1/3 octave Filter Set Type 1610, between the amplifier stages.
Features:
- Sensitivity: Full scale deflection from 100 microVolts to 1000 V in 10 db steps on two attenuators, Maximum amplification 100 db.
- Input Impedance: 2,22 MOhm parallelled by 30 picoFarad.
- Output Impedance: Smaller than 50 Ohm.
- Maximum available output is approx. 45 volts peak.
