Connect to the AQ6370 in Python

PROTOCOLS > SCPI

To connect to a Yokogawa AQ6370 Spectrum Analyzer using Instrumentkit, you can use the following Python script:

import instrumentkit as ik


# Connect to the Yokogawa AQ6370 Spectrum Analyzer
osa = ik.yokogawa.Yokogawa6370.open_visa('TCPIP0:192.168.0.35')


# Access the properties and methods of the Spectrum Analyzer
print(osa.id)
print(osa.start_wl)
print(osa.stop_wl)
osa.start_sweep()
data = osa.data()
wavelength = osa.wavelength()


# Close the connection to the Spectrum Analyzer
osa.close()

This script imports the instrumentkit module and opens a connection to the Yokogawa AQ6370 Spectrum Analyzer using the open_visa method. You can replace 'TCPIP0:192.168.0.35' with the appropriate VISA address of your Spectrum Analyzer.

Once connected, you can access the properties and methods of the Spectrum Analyzer. In the example script, it prints the identification (id) of the device, the start and stop wavelengths (start_wl and stop_wl), starts a sweep using start_sweep(), and retrieves the data and wavelength using data() and wavelength() methods.

Finally, the script closes the connection to the Spectrum Analyzer using the close() method.
