How to Set the Wavelength Directly

Keysight 81960A Compact TLS Module User's Guide
There are three ways to set the wavelength of the Tunable Laser.
• You can set the wavelength (
• You can set the wavelength from a base wavelength and an offset in the
frequency domain, or
• You can set a wavelength range for the instrument to "sweep".
Every Tunable Laser module has a specified wavelength range. This range
is available for all Tunable Laser modules. See "Keysight 81980A, 81960A,
81940A, 81989A, 81949A, and 81950A Compact Tunable Laser Sources
Data Sheet, publication number 5988-8518EN".
Every Tunable Laser module has a permitted wavelength range. This range
is greater than the specified range. The permitted wavelength range varies
for each Tunable Laser module. You can set the wavelength to any value
within the permitted wavelength range. For some specifications, a range
smaller than the permitted range applies, e.g. from 1525 to 1620 nm.
Figure 25 on page -49 shows an example of specified and permitted
wavelength range.

You can set a constant wavelength.
To set the wavelength to 1545.500 nm:
1 Move to the Tunable Laser channel.
2 Move to the wavelength parameter, [l], and press Enter.
3 Enter 1545.500 and press Enter.
