Using an External Generator
A generator with an output voltage between 0.5 V and 1.5 V can be connected to Type 4226. The
calibrator regulates the level in the coupler to ensure a constant SPL relative to the inverse
reference microphone response. When using an external generator, the inverse A-weighting and
the corrections for free-field and reference microphone response should not be applied since
they only refer to the frequencies delivered by Type 4226's generator.
