mpylab.device.sa_pmm_9010 module

PMM 9010 Analyzer Mode spectrum analyzer driver (chapter 14 remote protocol).

class mpylab.device.sa_pmm_9010.SPECTRUMANALYZER(**kw)

Bases: SPECTRUMANALYZER

Concrete PMM 9010 Analyzer Mode driver.

This driver reads Analyzer Mode traces via SAGO. PMM Sweep Mode is a receiver-oriented protocol path and is not exposed through this class.

GetAtt()

Return input attenuation in dB.

GetAttMode()

Return attenuation mode.

GetCenterFreq()

Return center frequency in Hz.

GetDescription()

Query and return the instrument identification string.

GetDetector()

Return detector mode.

GetPreAmp()

Return preamplifier setting in dB.

GetRBW()

Return the current PMM RBW in Hz or the last unknown value.

GetRefLevel()

Return cached display reference level in dBm.

GetSpan()

Return configured frequency span in Hz.

GetSpectrum()

Acquire one binary spectrum trace from the analyzer.

GetStartFreq()

Return start frequency in Hz.

GetStopFreq()

Return stop frequency in Hz.

GetSweepCount()

Return sweep count.

GetSweepPoints()

Return number of sweep points.

GetSweepTime()

Return sweep time in seconds.

GetTrace()

Return active trace number.

GetTraceMode()

Return trace mode.

GetTriggerDelay()

Return trigger delay in seconds.

GetTriggerMode()

Return trigger mode.

GetVBW()

Report that PMM Analyzer mode has no separate VBW setting.

Init(ini=None, channel=None, ignore_bus=None)

Initialize the analyzer from INI data and apply channel defaults.

Quit()

Stop analyzer operation.

SetAtt(value)

Set input attenuation in dB or enable automatic attenuation.

SetAttMode(value)

Set attenuation mode.

SetCenterFreq(value)

Set center frequency in Hz while keeping the current span.

SetDetector(value)

Set detector mode.

SetPreAmp(value)

Enable or disable the preamplifier.

SetRBW(value)

Set analyzer RBW via the PMM global RBW command.

SetRefLevel(value)

Set PMM display reference level in dBuV.

SetSpan(value)

Set frequency span in Hz around the current center.

SetStartFreq(value)

Set start frequency in Hz.

SetStopFreq(value)

Set stop frequency in Hz.

SetSweepCount(value)

Set sweep count.

SetSweepPoints(value)

Set number of sweep points.

SetSweepTime(value)

Set analyzer hold time in seconds.

The PMM Analyzer mode exposes a hold-time setting but no separate automatic hold-time command. For mpylab configuration compatibility, auto explicitly sets the one-second default.

SetTrace(value)

Set active trace number.

SetTraceMode(value)

Set trace mode.

SetTriggerDelay(value)

Set trigger delay in seconds.

SetTriggerMode(value)

Set trigger mode.

SetVBW(value)

Report that PMM Analyzer mode has no separate VBW setting.

mpylab.device.sa_pmm_9010.analyzer_trace_smoke_test(analyzer, output=<built-in function print>)

Read one short PMM Analyzer Mode trace and report its basic shape.

The helper expects an initialized SPECTRUMANALYZER instance and returns the (frequencies, levels_dbm) payload from GetSpectrum.

mpylab.device.sa_pmm_9010.main()

Run a minimal command-line smoke test for the PMM driver.
