Using the Wavelength functions
To set the center wavelength
1Press the
2Press the Center WL softkey.
3Use the knob, step keys or numeric entry pad to enter the desired value.
To set the wavelength span
1Press the
2Press the Span softkey.
3Use the knob, step keys or numeric entry pad to enter the desired value.
The span is set symmetrically about the center wavelength. When the span is set to 0 nm, the display’s horizontal axis represents time instead of wave- length. A span of 0 nm (called zero span mode) configures the optical spec- trum analyzer as a fixed tuned receiver.
To set the start wavelength
1Press the
2Press the Start WL softkey.
3Use the knob, step keys or numeric entry pad to enter the desired value.
To set the stop wavelength
1Press the
2Press the Stop WL softkey.
3Use the knob, step keys or numeric entry pad to enter the desired value.
