User-Definable Step Size
To set the user-definable step size:
1.
Press
shift/exit
, then
STEP SIZE
for three seconds. The larger digits flash,
indicating the current variable step size setting.
2.
Set the desired step size using
or
. The maximum step size value
is 60.00 dB.
3.
Press
shift/exit
to confirm selection. The variable step size is now programmed
and is the currently selected step size.
Programming the Unit
The unit can be programmed for automatic operation. The program permits up to
60 attenuation steps with a time interval of up to 60 hours (minus one second)
between each step. Attenuation changes between
−
0.05 dB and
−
70 dB (minus the
insertion loss) may be introduced. You can define program parameters for each of
the available wavelengths.
To program the unit:
1.
Select the appropriate wavelength by pressing
shift/exit
, then
λ
SELECT
. To
program wavelengths, see
Programming Wavelengths
on page 7.
2.
Press
program
for three seconds to activate program setup. A flashing value,
between 00 and 59, defines the number of attenuation steps in your program.
Press

A flashing value, between
−
00.00 dB and
−
70.00 dB, defines the size of each
attenuation step. Press
or
to select a number in 00.05 dB steps.
The program parameters have now been defined. To cycle through the five
parameters, press
