Using Span to Zoom in on a Portion of the Response

To see a more detailed view of the device's response, decrease the span to
expand the trace. This will enable you to precisely focus in on the desired
measurement area.
This procedure assumes that you have normalized your test setup and posi-
tioned the response on the display. For more information on these processes,
refer to "Normalizing the Measurement" on page 3-11 and refer to "Status
Reporting for Laser Wavelength Zeroing" on page 3-13.
• Press Wavelength > Span and reduce the span to 2 nm.
Reducing the span allows you to zoom in on desired portions of the response.
