LINE
The connector for AC power supply
The included power cable (A01402) is connected here.
23. Fuse holder assembly
The power supply voltage can be selected from 100 V, 120 V, 220
V, and 240 V.
A slow-blow fuse is used.
24. USB
The USB connector which is used for the data communications
and used to remotely control this instrument.
25. GP-IB
The GPIB connector which is used for the data communications
and used to remotely control this instrument.
26. ANALOG OUTPUT
Outputs the voltage which is proportional to the optical power.
The full-scale value is changed depending on the measurement
range because the voltage is output before the AD conversion.
The ZERO cancellation is not reflected on the output.
The level calibration and the wavelength sensitivity correction of
the sensor, and the calculation such as MAX or dB are not
reflected on the analog output.
The output voltage is 0 to +2 V (Full-scale) and the output imped-
ance is 10
or less. The BNC connector is used.
