The software can perform calibration on any single tone, multilevel calibrators at 250 Hz and 1000 Hz in the level range 94 dB to 124 dB.
The system uses the comparison method with Pistonphone Type 4228 as sound level reference. PULSE Multi-analyzer System Type 3560 can compare the reference sound pressure level with the sound pressure level generated by the tested calibrator and measure frequency and distortion.
Calibration procedures for Brüel & Kjær Types 4220, 4228, 4230 and 4231 are included in the system software, and tools to add new types and procedures are included as well. All procedures and calibration results are stored in the system’s database.
