The built-in compressor amplifier maintains regulation up to 55 dB and will
maintain a constant voltage, current or sound pressure level to within 1.5 dB
over the whole frequency range. Linearity of the frequency characteristic is
better than ±0.3 dB.
Regulation speed variable in steps: 30-100-300-1000 dB/sec.
Frequency Deviation
Internal: Variable in steps, 0 ± 10 ± 16 ± 25 ±40 ± 63 ± 100 ± 160
±250Hz
External: With external generator continuously variable from 0 to
±300Hz. Maximum Modulation Sensitivity 5 mV/Hz (at 250Hz frequency
deviation).
