External wavelength locking

(Agilent 81480/

81680A/640A/682A/642A)

> ±70 pm at 10 Hz

Coherence control

(81480A/81640A/81642A/ 80A/ 82A)

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.

Continuous sweep mode

(81480A/81640A/81462A/ 80A/ 82A)

Tuning velocity adjustable to

40 nm/sec, 5 nm/sec and 0.5 nm/sec.
