Outline The program function means that measuring conditions, measuring procedures and other data are registered and executed. There are 200 steps per program and 20 programs can be created. Created programs are stored in nonvolatile memory and also can be stored in the built-in floppy disk. By using this function, automatic measurement can be performed without any external computer.
Page 262: Program Input
Program Input When the <PROGRAM EDIT> key is pressed, the screen shown in Fig. 6-1 is displayed. Fig. 6-1 Screen Displayed by Pressing <PROGRAM EDIT> key In the No. column, program Nos. 01 to 20 are displayed. In the US column, "*" is displayed when the corresponding program No. is already registered. In the program name display area, program names are displayed.
Page 263: Program Name Input And Change
6.2.1 Program name input and change To a program, a comment of up to 50 characters can be attached as its program name. On the screen shown in Fig. 6-1, enter a program name and select a program name to be changed by moving the display in reverse video in the No.
Page 264: Program Input And Change
6.2.2 Program input and change On the screen shown in Fig. 6-1, move the display in reverse video in the No. column to the program No. to be entered or changed, and then press the <EDIT> key. Then, the program input screen shown in Fig. 6-2 is displayed.

When using the markers, the [MARKER] switch of the [FUNCTION] section is used. 2 * There are two types of marker, namely, line marker and marker. The line marker is classified into the wavelength line marker (for the axis of ordinates) and the level line marker (for the axis of abscissas).

Page 370: Marker-To-Marker Sweep Function
5 0, 5 *77*% The marker-to-marker sweep function permits a sweep between the wavelength line marker 1 and wavelength line marker 2. Because the sweep range is limited to the section between the marker 1 and marker 2, high-speed sweep processing can be executed.
Page 371 Only this range is swept. After Execution of Marker-to-Marker Sweep Function To cancel the marker-to-marker sweep function, press the [SWEEP] switch. In the soft key menu displayed by this operation, press the <SWEEP MKR L1-L2> key again to reset its display in reverse video into the initial status.

Page 452: Configuration And Principle Of Monochromator
10.1 Configuration and Principle of Monochromator 10.1.1 Principle of monochromator This equipment is provided with a Zollner-Thurnar's type monochromator. Figure 10-1 shows the basic configuration. Light output slit Focusing mirror Grating Collimate mirror Depolarizing element Light input slit Fig. 10-1 Basic Configuration of Monochromator The light input from the light input slit is changed into parallel light by the collimate mirror and enters the grating.
Page 453: Signal Detector
10.1.2 Signal detector The light coming out from the monochromator is led to the signal detector. Monochromator Optical sensor Chopper Fig. 10-2 Signal Detector Configuration When the measuring sensitivity is set to HIGH1 to 3, light chopping is performed by the optical chopper built in the monochromator.

Monochromator AMP circuit Sensor CPU 2 GPIB 1 Keyboard CPU 1 GPIB 2 Display unit CPU 1 Printer Fig. 10-3 Circuit Configuration of this Equipment The grating of the monochromator controls the angle by means of a stepping motor. The stepping motor is used to set a width to the slit, too.
Page 455: Precautions On Measurement
10.3 Precautions on Measurement This equipment is designed for different purposes but has some restrictions. Be careful about the following items at measurement. 10.3.1 Types of optical fiber usable in this equipment This equipment can use the single mode optical fiber with a core diameter of 5 to 10 µm and the GI fiber with core diameters of 50 and 62.5 µm for the optical input.
Page 456: Absolute Level Accuracy
10.3.3 Absolute level accuracy The absolute level of this equipment is calibrated by SM 10 µm fiber. The level accuracy, when the other fibers are used, is out of specification. As a matter of practical efficiency, any SM fiber other than the SM 10 µm fiber will provide an almost accurate level.
Page 457: Stray Light In The Sens:normal Mode
10.3.5 Stray light in the SENS:NORMAL mode If you select the SENS:NORMAL HOLD or NORMAL AUTO for the measurement gain, optical noises can uniformly appear in the lower spectrum level (see Figure 10-4). Also in the same mode, optical noises with the spectrum level of approximately lower than their original level by 30 to 50 dB can appear in the position 100 to 200 nm away from the peak wavelength.
Page 458: Ripple Around 1380 Nm
10.3.6 Ripple around 1380 nm As the optical beam around 1380 nm is absorbed by a water (OH group) existing in the monochromator, a ripple may be formed on the measured waveforms. The basic solution is the setup of wider resolution for ripple averaging. For LED measurement, please set 2nm to the resolution 10.3.7 Level accuracy below fiber cable cutoff wavelength...
Page 459: Numerical Aperture (Na) Of Input Optical Fiber And Level Measured Value
10.3.9 Numerical Aperture (NA) of Input Optical Fiber and Level Measured Value Level measurement error of this equipment varies with the numerical aperture (NA) of optical fiber to be connected to the optical input connector as shown in Figure 10-7. The absolute level of this equipment has been calibrated with the 10/125µm single mode optical fiber (B1.1 type defined on IEC60793-2, PC polished, Mode field diameter 9.5µm, NA: 0.104~0.107).
