lightlab.equipment.lab_instruments.Apex_AP2440A_OSA module

Summary

Classes:

Apex_AP2440A_OSA

Class for the OSA

Functions:

check_socket

Data:

WIDEST_WLRANGE

list() -> new empty list list(iterable) -> new list initialized from iterable’s items

Reference

check_socket(host, port)

class Apex_AP2440A_OSA(name='The OSA', address=None, **kwargs)

Bases: lightlab.equipment.visa_bases.visa_driver.VISAInstrumentDriver

Class for the OSA

Basic functionality includes setting/getting wavelength range and sweeping Other functionality is for controlling TLS: on/off, wavelength (not implemented)

The primary function is spectrum, which returns a Spectrum object

Usage: Instrument: OpticalSpectrumAnalyzer

Initializes a fake VISA connection to the OSA.

instrument_category

alias of lightlab.laboratory.instruments.interfaces.OpticalSpectrumAnalyzer

MAGIC_TIMEOUT = 30

reinstantiate_session(address, tempSess)

startup()

Checks if it is alive, sets up standard OSA parameters

open()

close()

query(queryStr, expected_talker=None)

write(writeStr, expected_talker=None)

The APEX does not deal with write; you have to query to clear the buffer

instrID()

Overloads the super function because the OSA does not respond to *IDN? Instead sends a simple command and waits for a confirmed return

getWLrangeFromHardware()

wlRange

triggerAcquire()

Performs a sweep and reads the data Returns an array of dBm values as doubles :rtype: array

transferData()

Performs a sweep and reads the data

Gets the data of the sweep from the spectrum analyzer

Returns:wavelength in nm, power in dBm Return type:(ndarray, ndarray)

spectrum(average_count=1)

Take a new sweep and return the new data. This is the primary user function of this class

tlsEnable
