Setting the Measurement Range
4. Use the arrow buttons next to the Scale list and highlight the scale you
wish to use.
The table on the following page displays the permitted scales when the
currently selected measurement unit is dB or dBm. The power values
displayed are typical at 1550 nm.
Note: You can have a high acquisition rate only if a manual range is set on all
channels.
5. Click Apply to confirm your new setting.
Note: You can also use the All Channels button to modify all channels identically.
If other values were set previously, but are different from those you are
currently setting, any value you change will turn red to indicate that it is
different.
