GEN Generic devices

This HAL type includes various device which are required to conducted the experiment and do not fall into any of other category. Generally, these instruments have simple configuration, and very limited number or parameters are changed during the experiment. Currently we have the following generic insturments:

Attenuator (Vaunix).
Microwave sources (R&S).
Switch (custom rpi based).
Voltage source (IVVI, SIMRACK).

Following is the list of functions or parameters: ___

Attenuator

Binding to lab:

Bind Qcodes driver to Lab object.

stz.GENatten('rf_atten', lab, ['VaunixAtten', 'CH1'])

Attenuation Value

Set or get Attenuation value in dB.

lab.HAL('rf_atten').Attenuation = 12

Microwave Sources

Binding to lab:

Bind Qcodes driver to Lab object.

stz.GENmwSource("MW_cav", lab, 'src_sgs2', 'RFOUT')

Output state:

Turn the output ON (True) or OFF (False).

lab.HAL("MW_dnc").Output = True

Power:

Set or get the power of source in dB.

lab.HAL("MW_cav").Power = -35

Frequency:

Set or get the frequency of the souce in Hz.

lab.HAL("MW_cav").Frequency = 1e6

Phase:

Set or get the starting phase of the souce in radians.

lab.HAL("MW_cav").Phase = 3.14

Mode:

Set the output mode of the source. It can be Continuous or PulseModulated.

python
lab.HAL("MW_cav").Mode = "Continuous"

Trigger Source:

Set or get trigger source, which is a trigger Object type.

lab.HAL("MW_cav").set_trigger_source(<trigger object type>)

Manual Activation(!!):

Experiment Configuration can automatically turn insturments “ON” and “OFF” based on when they are needed. If you would like to Disable it, set this property to True.

lab.HAL('MW_CLK').ManualActivation = True

Switch

Binding to lab:

Bind Qcodes driver to Lab object.

stz.GENswitch('sw_radial_rt', lab, 'sw_rpi_radial_rt')

Position:

Set of get the position.

lab.HAL('sw_radial_rt').Position = 'P2'

Voltage Source

Binding to lab:

Bind Qcodes driver to Lab object.

stz.GENvoltSource('vFlux1', lab, ['sim_rack928','CH3'])

Output state

Turn the output ON (True) or OFF (False).

lab.HAL("vFlux1").Output = True

Voltage:

Set or get the output voltage.

lab.HAL("vFlux1").Voltage = 1.0

RampRate:

Set or get the rate of change of voltage in Volts/second.

lab.HAL("vFlux1").RampRate = 0.01

Manual Activation(!!):

Experiment Configuration can automatically turn insturments “ON” and “OFF” based on when they are needed. If you would like to Disable it, set this property to True.

lab.HAL("vFlux1").ManualActivation = True

This completes all the available Generic HAl device. It is recommended to read AWGWavefrom section now.
