mpylab.device.pm_gt_8542c_multichannel module

Shared-transport, two-channel driver for the Giga-tronics 8542C.

class mpylab.device.pm_gt_8542c_multichannel.POWERMETER(**kwargs)

Bases: SharedPowerMeterFacade, POWERMETER

Expose both GT 8542C inputs through one shared communication session.

The instrument’s ordinary AP/BP interface provides independent, sequential readings. It does not guarantee simultaneous acquisition. Therefore acquisition=synchronized is rejected explicitly.

GetData()

Read this channel and return a power quantity.

GetDataNB(retrigger=False)

Return the current free-running value without a pending state.

GetFreq()

Return the last correction frequency assigned to this channel.

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

Initialize one strict channel facade and the instrument once.

SetFreq(freq)

Set this sensor input’s correction frequency.

Trigger()

Return success because the 8542C channels run continuously.

Zero(state='on')

Zero this input when state is on.

mpylab.device.pm_gt_8542c_multichannel.main()

Print the embedded virtual two-channel smoke-test result.

mpylab.device.pm_gt_8542c_multichannel.virtual_smoke_test()

Exercise both facades without hardware.
