class mpylab.device.pm_gt_8540c.POWERMETER(**kw)

Bases: POWERMETER

Driver for the Gigatronics 854X powermeter

GetData()

Read one power sample and return it as quantity with mismatch uncertainty.

GetDataNB(retrigger=False)

Return data and optionally retrigger for the next read.

GetDescription()

Return instrument identification string.

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

Initialize the selected meter channel and apply presets.

Quit()

Close the driver and return status.

SetFreq(freq)

Set measurement frequency in Hz.

Trigger()

Trigger measurement acquisition (no-op for this backend).

Zero(state='on')

Run zeroing sequence and return status.
