status

method

TSL550.status(verbose: bool = False) → str

Query the status of the laser and print its results.

Parameters:

verbosebool, optional

If True, print the string status of each parameter (default False).

Returns:

codestr

A status code for the status of the laser.

The following example shows the laser as on and all operations as complete.

Notes

The status code is a 7-character string status comprising a code and 6 digits (with positions represented as ‘-654321’), interpreted as follows:

Code [-/none]: Laser diode (LD) status

‘-’: ON

none: OFF

6th digit [0/1]: Coherence control

0: OFF

1: ON

5th digit [0/1]: Fine-tuning

0: OFF

1: ON

4th digit [0-5]: Control mode of output power, attenuator, and power

monitor range, according to the following table:

Value	Power control	Attenuator control	Power monitor range control
0	Auto	Hold	Auto
1	Manual	Hold (Manual)	Auto
2	Auto	Auto	Auto
4	Auto	Hold	Hold
5	Manual	Hold (Manual)	Hold

3rd digit [0/1]: Laser diode temperature error

0: No error

1: Error occurred

2nd digit [0/1]: Laser diode current limit error

0: No error

1: Error occurred

1st digit [0-7]: Operation status

0: Operation is completed

1: Wavelength is tuning

2: Laser diode current is setting (LD is on state and power control is Auto)

3: Wavelength is tuning and LD current is setting

4: Attenuator is setting

5: Wavelength is setting and attenuator is setting

6: LD current is setting and attenuator is setting

7: Wavelength is tuning, LD current is setting, and attenuator is setting
