AC、 、 、 、 DC Output
AC Output
The AC Output is the frequency-weighted signal.
Output: 1Vrms (FS), Output impedance: 600Ω, Load impedance > 10kΩ
DC Output
The DC Output is the frequency-weighted, root-mean-square-detected, and then logarithmic
converted signal.
Output: 2.5V (FS), 0.25V/10dB, Output impedance: 50Ω, Load impedance > 10kΩ
