9 To deselect a Power Meter channel, move to the Power Meter as
denoted by slot and channel numbers, see "Slot and Channel
Numbers" on page 40, press [Unset].
10 To select a Power Meter channel, press [Edit], move to the Power
Meter as denoted by slot and channel numbers, see "Slot and
Channel Numbers" on page 40, press [Set].

Setting Sweep Parameters

12 Move to [λ Start], press Enter, enter the start wavelength of the
sweep, and press Enter.
13 Move to [λ Stop], press Enter, enter the stop wavelength of the
sweep, and press Enter.
14 Move to [Step], press Enter, enter the step size for the sweep, and
press Enter.
N O TE
The step size defines:
• the size of the change in the wavelength for each step of a stepped
sweep and
• the wavelength interval between power measurements, the first
power measurement is taken at [λ Start] and the last must be taken
at [λ Stop].
15 Move to [P max], press Enter, enter the maximum power in dBm for
the sweep, and press Enter. The instrument chooses a constant
power level for the measurement using the following constraints:
– the power will be less than or equal to the [P max] value you set
and
– the power will be less than or equal to the maximum power
possible for the chosen Tunable Laser module across the chosen
wavelength range.
16 Move to [Method], press Enter, and move to one of the following
sweep modes:
– <Stepped>, which dwells at wavelengths that are separated by a
certain step size, or
