Spectrum Analyzers
This module provides support for controlling spectrum analyzers with Python.
Spectrum analyzers can be imported by
>>> import hardware
>>> lia = hardware.spectrum_analyzers.ANDO_AQ6317B('GPIB0:...')

class
hardware.spectrum_analyzers.ANDO_AQ6317B(visa_search_term)[source]
Hardware wrapper for ANDO AQ6317B Optical Spectrum Analyzer
| Parameters: | visa_search_term (str) – The address that is passed to
visa.ResourceManager().open_resource() |
|---|
-
acquire(channel='B')
Returns the measured spectrum from a single reading of the instrument.
Aliases to acquire
| Returns: | tuple of arrays – The first array contains the wavelengths in nanometers.
The second array contains the optical power in dBm. |
|---|
-
get_spectrum(channel='B')[source]
Returns the measured spectrum from a single reading of the instrument.
Aliases to acquire
| Returns: | tuple of arrays – The first array contains the wavelengths in nanometers.
The second array contains the optical power in dBm. |
|---|
-
identify()[source]
| Returns: | str – The response from an *IDN? GPIB query. |
|---|
-
set_timeout(milliseconds)[source]
Sets the timeout of the instrument in milliseconds.
| Parameters: | milliseconds (float) – The timeout in milliseconds |

-
class
hardware.spectrum_analyzers.Rohde_Schwarz_FSEA_20(visa_search_term)[source]
Hardware wrapper for Rohde & Schwarz FSEA 20 RF Spectrum Analyzer
| Parameters: | visa_search_term (str) – The address that is passed to
visa.ResourceManager().open_resource() |
|---|
-
acquire()[source]
Returns a tuple of the frequencies (Hz) and powers of the trace.
For the resolution bandwidth, use the rbw property.
