8250A Optical Power Meter Operation Manual
8.1.2 General Specifications
8-2
the power meter, is used.
Calibration Wavelength Selection Function:
This function operates when the "Calibration wavelength addition" option is
set in the sensor.
"Measurement accuracy at the calibration wavelength" can be applied at mul-
tiple wavelengths.
Wavelength preset function:
Four wavelengths, at which the wavelength sensitivity correction is per-
formed, can be registered. (This function can be set only by the panel opera-
tions.)
Smoothing function:
Moving average from 2 to 100 times
Offset zero:
Stores the sensor offset in memory and automatically corrects it.
MAX value hold function: Holds the maximum measured value
Relative value display function:
Ratio (in the W unit display), dBr (in the dBm unit display)
Interface
Analog output:
Can be output according to the input signal.
When using an 823* series sensor: The full-scale value changes depending on
the sensitivity calibration value of the sensor, wavelength setting, correction
value (CF), and the range setting.
When using an 821* series sensor: The full-scale value changes depending on
the wavelength setting, correction value (CF), and the range setting.
Output voltage: 0 to 2 V
Output resistance: 10
or less
Output connector: BNC
USB interface:
In compliance with USB2.0 Full Speed
Connector: USB B type (female)
GPIB interface:
In compliant with IEEE-488
Connector: 24-pin amphenol
Interface Function: SH1, AH1, T5, L4, SR1, RL1, PP0, DC1, DT1, C0, E2
Backup function:
Can be stored four setting conditions and the setting conditions saved when the
power turns off. The settings loaded when the power turns on can be selected.
Other functions:
Key lock, CF calculation, and the number of displayed digits selection
