Microphone calibration system

Microphone Calibration Systems enabling you to make faster and more accurate electrical transfer impedance measurements of coupled microphones. This makes multiple-frequency calibration possible as the time required per step is considerably reduced. The included measurement and calculation software is one of the benefits of using Brüel & Kjær's Microphone Primary Calibration System. The software controls the system via an IEEE–488 bus and handles the calculations, making measurement task semi-automatic - greatly reducing the risk of making errors in the calculation of the calibration results.
