Selecting/Deselecting Power Meters
8 Move to the Module Selection box. As a default, all Power Meters are selected,
this means that all Power Meters will log power measurements. Press [Edit].
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 36, 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 36, press [Set].
11 Perform steps until you have selected the required Power Meters for your
application and press Enter.
NOTE If no Power Meter channel is selected, you cannot exit by pressing Enter.
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.
NOTE 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
– <Continuous>, which sweeps continually at the speed you set.
Press Enter.
