mpylab.device.pm_rxatt module

Composite power meter driver with automatic RX attenuation switching.

class mpylab.device.pm_rxatt.POWERMETER(**kw)

Bases: POWERMETER

Power meter wrapper that compensates fixed-path attenuator networks.

GetData()

Acquire one measurement and compensate attenuation path settings.

GetDataNB(retrigger=False)

Return non-blocking data and apply attenuation compensation when available.

GetDescription()

Return combined wrapper and underlying meter description.

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

Initialize underlying power meter and RF switch controller.

Quit()

Shut down all delegated devices and return success.

SetFreq(freq)

Set frequency for meter/switch and update path correction factors.
