DC Output
A level-converted DC signal generated by rms detection and logarithmic
compression is output. The signal reflects the frequency weighting and time
weighting settings of the unit.

Output voltage: 2.5 V ±50 mV (scale upper limit), 0.25 V / 10 dB
Output impedance: approx. 50 Ω
Load impedance: 10 kΩ or higher
Suitable cable: BNC-to-RCA cable CC-24 (option)
The relationship between unit reading and output voltage is as follows.
The output voltage when the unit is in calibration mode (-6 dB from scale
upper limit) is 2.35 V.
To use the DC output, set the item "Output AC/DC" on menu screen 3/5 to
"DC".
