9. OUTPUT CONNECTORS
AC Output:
An AC signal corresponding to the frequency-weighted signal is available at this
connector.
Output voltage: 1Vrms±50mVrms (scale upper limit)
Output impedance: approx. 5kΩ
Load impedance:≧1MΩ
The output voltage when the meter is in calibration mode
(-16dB from scale upper limit, 1000Hz sine wave) is 158.5mVrms.
DC Output:
A level-converted DC signal generated by RMS detection and logarithmic
compression is available at this connector. The signal reflects the frequency
and time weighting settings of the instrument.
Output voltage: 10mV±0.1mV/dB
Output impedance: approx. 5kΩ
Load impedance:≧1MΩ
The output voltage when the meter is reading 114dB is nominally 1.14V DC.
