Measuring Wavelength and Power

List by WL or Power modes

In the list- by- wavelength or list- by- power modes, the measurements of

five laser lines can be displayed at any one time. Use the and

softkeys to move the cursor through the list of signals; the list can contain up to 200 entries. Press the SELECT key, and the display changes to peak wavelength mode with the signal at the cursor dis- played.

Annotation in the upper right corner of the display indicates whether the signals are ordered according to wavelength (BY WL) or power (BY PWR). The cursor shows the currently selected laser line. As you scroll through the responses, the current position of the selection cursor is shown along the screen’s right side.

Also notice that power bars graphically show the relative power levels between laser lines.

To display multiple laser lines

1Connect the fiber- optic cable to the front- panel OPTICAL INPUT connector.

2Press the green Preset key.

3Press List by WL to display the laser lines from the shortest wavelength to the longest wavelength.

4Press List by Power to display the laser lines in order of decreasing amplitudes.
