Bandwidth/Wavelength....
You can use the Bandwidth/Wavelength.... softkey to change the bandwidth and
wavelength settings.
This function is available on the electrical channel only.
You can use the Bandwidth function to select either the 18 GHz or 40 GHz
bandwidth.

The Filter function turns the filter on and off.
Channel, Bandwidth/Wavelength...., Filter On Off
This function is only available on the optical channel.
The Wavelength function selects the desired wavelength for calibrated mea-
surements. Factory calibrated wavelengths are 1310 nm and 1550 nm. A user-
calibrated wavelength is also available and can be calibrated in the range from
1000 nm to 1600 nm. Refer to Chapter 3, "Calibration Overview" for additional
information on performing a calibration.

Channel autoscale
The Channel Autoscale function provides a convenient and fast method for
determining the standard vertical scale setting with the highest resolution that
will not clip the waveform. Timebase and trigger settings are not affected.
This function is useful in manufacturing environments where the timebase
and trigger settings remain constant and only the vertical scale needs to be
adjusted for signal level variations in multiple DUTs.
