Specifications
Each laser line is assumed to have a linewidth (including modulation sidebands) of
less than 10 GHz.
All specifications apply when the instrument is in the following modes:
• NORMAL update mode unless noted. Refer to “Measurement rate” on page 50 .
• Configured to measure narrowband devices. Specifications do not apply when the in-
strument is configured to measure broadband devices. Refer to “Measuring broad-
band devices and chirped lasers” on page 46 .
