How to Modulate a Signal
There are two ways of modulating the amplitude of the optical output.
• Using the internal modulation, and
• using external modulation.
How to Use the Internal Modulation
The internal modulation is a square wave with a 50% duty cycle. You can
set both the amplitude and the frequency of this signal. The amplitude is
set by the power parameter. This is the maximum output power of the
output signal; at the minimum output power, no power is output.

The Modulated Signal
How to Set the Output Power of a Modulated Signal
To set the output power to 555.000
μ
W:
1 Move to the Tunable Laser channel and press [Details] softkey.
2 Move to the power parameter, [
P],
and press [Pwr unit].
3 Move to <
W
>, by using the cursor key, and press
Enter
.
4 Press
Enter
to start editing the output power value.
5 Enter 555.000, press [Unit+] or [Unit
-
], as required, to select <
μ
W> as
the power units, and press
Enter
.
How to Set the Frequency of a Modulated Signal
To set the frequency of the modulation to 6.500 kHz:
6 Move to the frequency parameter, [
Mod Frq
], press
Enter
.
7 Enter 6.500 press
Enter
.
NOTE
The signal modulation feature is not available when Auto Cal Off is
selected.
