Programming Wavelengths
The FVA-60B offers calibrated wavelength at ± 30 nm (in 10 nm steps) from the
standard singlemode and multimode wavelengths.
To program wavelengths:
1.
Press shift/exit , then λ SELECT for three seconds. The currently selected
wavelength flashes.
2.
Press or to toggle between available wavelengths.
3.
Press program to confirm selection.
4.
Repeat step 2 to select a second wavelength and press program to confirm
selection. Upon confirmation of second wavelength, the unit exits the
Wavelength Programming mode.
Note:
To see the currently selected wavelength when you are in relative or
X + B mode, switch to the alternate wavelength and back. The new
setting is briefly displayed.
Setting Attenuation Step Sizes
The unit has four attenuation step sizes that permit different scanning speeds and
resolutions:
➤
0.05 dB step size and resolution (default when powering on the unit)
➤
0.2 dB step size and resolution
➤
1 dB step size and resolution
➤
User-definable step size with 0.05 dB resolution
Note:
Selecting a larger step size allows for faster attenuation scanning.
Standard Step Sizes
To select a standard step size:
1.
Press shift/exit , then STEP SIZE .
2.
Press STEP SIZE again to toggle between step size options.
3.
Press shift/exit to confirm selection.
4.
Pressing or changes the attenuation one step.
Note:
Selecting one of the three standard step sizes affects the resolution of
the attenuation setting and may cause rounding off of the currently
selected attenuation value.
