Calibration – Band-pass filters
About
Accredited calibration of the 1/1 and 1/3 octave-band filters. Measurement method in accordance with PN-EN 61260: 2000 or PN-EN 61260-3: 2016.
In measurements made in accordance with PN-EN 61260: 2000, we indicate:
• relative attenuation
• errors of linearity and linear range
• the flat frequency response
In measurements performed in accordance with 61260-3: 2016, we indicate:
• relative attenuation
• measurement of the lower limit of linearity
• linearity errors and linear range
• linearity taking into account the influence of the range switch
• measurement of the relative attenuation for the center frequencies of the filters
