External digital modulation
> 45% duty cycle
delay time < 300 ns, 200 Hz to 1 MHz.
Displayed wavelength represents average wavelength.
Modulation input (mainframe): TTL signal.
External analog modulation
≥ ±15% duty cycle
5kHz to 20MHz
Modulation input (mainframe): 5 Vp-p
External wavelength locking
> ±70pm at 10Hz

Coherence Control:
For measurements on components with 2 m long patchcords and
connectors with 14 dB return loss, the effective linewidth results in a
typical power stability of < ±0.025 dB over 1 minute by drastically reducing
interference effects in the test setup.
