Auto Cal Off
The disabling of the Auto Calibration feature enables the TLS to operate for
a long period without interrupting the operation for “Auto Lambda Zeroing
(setting)”. When Auto Calibration is disabled, it is possible to operate the
TLS at a temperature that differs more than 4.4 K from the last Lambda
Zeroing temperature. In this case, the accuracy and wavelength
performance of the TLS can become less optimal due to temperature
variation. The relevent accuracy class is indicated on the user interface
when Auto Calibration is off.
The Auto Calibration mode is NOT stored in the Instrument Settings. After
reboot or preset the Auto Calibration is always on. Agilent VEE will send a
preset before scanning for devices as default. This default preset can be
disabled.
When Auto Cal Off is selected the digital signal modulation feature is not
available.
See the table below for the wavelength accuracies of ACC1, ACC2, and
ACC3.

To get the specified performance ensure the warm-up time has passed and
execute then a Lambda Zero before switching Auto Cal off.
