TEKTRONIX RSA6120B, RF spectrum analyzer

Manual

Usage: TODO

Fairly simple class for getting RF spectra. The RSA6120 has a lot of advanced functionality, like spectrograms, which could be implemented later.

instrument_category

alias of lightlab.laboratory.instruments.interfaces.RFSpectrumAnalyzer

startup()

getMeasurements()

Returns:tokens of currently active measurements Return type:(list[str])

setMeasurement(measType='SPEC', append=False)

Turns on a measurement type

If append is False, turns off all measurements except for the one specified

See manual for other measurement types.

run(doRun=True)

Continuous run

After transferring spectra remotely, the acquisition stops going continuously. Call this when you want to run the display live. Useful for debugging when you are in lab.

sgramInit(freqReso=None, freqRange=None)

sgramTransfer(duration=1.0, nLines=100)

Transfers data that has already been taken. Typical usage:

self.sgramInit()
... << some activity >>
self.run(False)
self.spectrogram()

Currently only supports free running mode, so time is approximate. The accuracy of timing and consistency of timing between lines is not guaranteed.

spectrum(freqReso=None, freqRange=None, typAvg='none', nAvg=None)

Acquires and transfers a spectrum.

Unspecified or None parameters will take on values used in previous calls, with the exception of typAvg – you must explicitly ask to average each time.

Parameters:

• freqReso (float, None) – frequency resolution (typical = 1e3 to 10e6)
• freqRange (array-like[float], None) – 2-element frequency range
• typAvg (str) – type of averaging (of [‘none’, ‘average’, ‘maxhold’, ‘minhold’, ‘avglog’])
• nAvg (int, None) – number of averages, if averaging

Returns:

power spectrum in dBm vs. Hz

Return type:

(lightlab.util.data.Spectrum)
