How to Modulate the Optical Output

How to Change Modulation Source
The Modulation Source parameter, [Mod Src], allows you to modulate the
output signal. This parameter can be set to Off, Internal, Coherence
Control, or Backplane.
For details of the Off setting "How to Disable Modulation" on page 113.
For details of the Internal setting "How to Use the Internal Modulation" on
page 114
For details of the Coherence Control setting "How to Increase Linewidth"
on page 114
For details of the Backplane setting "External Digital Modulation using
Input Trigger Connector" on page 147.
How to Disable Modulation
If <Off> is displayed as the Modulation Source parameter, [Mod Src], the
laser source outputs an unmodulated continuous-wave signal.
To disable modulation:
1 Move to the Laser Source channel and press [Details] softkey.
2 Move to the modulation source parameter, [Mod Src], and press Enter.
3 Move to <Off>, by using the cursor key, and press Enter.
