Return type

Quantity

is_locked()

Whether the front panel is locked or not

lock(lock=True)

Lock the front panel of the wavemeter, preventing manual input

When locked, the wavemeter can only be controlled remotely by a computer. To unlock, use unlock() or hit the ‘Remote’ button on the wavemeter’s front panel.

set_num_averaged(num)

Set the number of samples used in averaging mode

When averaging mode is enabled, the wavemeter calculates a running average of the last num samples.

Parameters

num (int) – Number of samples to average. Must be between 2 and 50.

set_setpoint(setpoint)

Set the wavelength setpoint

The setpoint is a fixed wavelength used to compute the deviation. It is used for display and to determine the analog output voltage.

Parameters

setpoint (Quantity) – Wavelength of the setpoint, in units of [length]

unlock()

Unlock the front panel of the wavemeter, allowing manual input
