__init__(parent: RohdeSchwarz_SMW200A, name: str, hwchan: int)

Combines all the parameters concerning the pulse generator for setting output of the pulse modulation signal. Available only with option SMW-K23 installed.

Parameters:

• parent – the parent instrument of this channel

• name – the internal QCoDeS name of this channel

• hwchan – the internal number of the hardware channel used in the communication

polarity

Sets the polarity of the pulse output signal. Values are: ‘NORM’: Outputs the pulse signal during the pulse width, that means during the high state. ‘INV’: Inverts the pulse output signal polarity. The pulse output signal is suppressed during the pulse width, but provided during the low state.

output

Activates the output of the pulse modulation signal. Values are: ‘OFF’ or ‘ON’.

state

Enables the output of the video/sync signal. If the pulse generator is the current modulation source, activating the pulse modulation automatically activates the signal output and the pulse generator.

class qcodes_contrib_drivers.drivers.RohdeSchwarz.SMW200A.PulseModulation(parent: RohdeSchwarz_SMW200A, name: str, hwchan: int)

Bases: InstrumentChannel

__init__(parent: RohdeSchwarz_SMW200A, name: str, hwchan: int)

Combines all the parameters concerning the pulse modulation.

Parameters:

• parent – the parent instrument of this channel

• name – the internal QCoDeS name of this channel

• hwchan – the internal number of the hardware channel used in the communication

state

Activates/deactivates the pulse modulation. Values are ‘ON’ and ‘OFF’.

source

Selects the modulation source. Values are:

• ‘INT’: internally generated signal is used (only available with option SMW-K23)

• ‘EXT’: externally supplied signal is used

transition_type

sets the transition mode for the pulse signal. Values are:

• ‘SMO’: flattens the slew , resulting in longer rise/fall times (SMOothed)

• ‘FAST’: enables fast transition with shortest rise and fall times

video_polarity

Sets the polarity of the pulse video (modulating) signal, related to the RF (modulated) signal. Values are:

• ‘NORM’: the video signal follows the RF signal, that means it is high when RF signal is high and vice versa

• ‘INV’: the video signal follows in inverted mode

polarity

sets the polarity of the externally applied modulation signal

• ‘NORM’: Suppresses the RF signal during the pulse pause

• ‘INV’: Suppresses the RF signal during the pulse

impedance

Sets the impedance for the external pulse modulation input. Values are ‘G50’ and ‘G1K’

trigger_impedance

Sets the impedance for the external pulse trigger. Values are ‘G50’ and ‘G10K’

mode

(Only SMW-K23) Selects the mode for the pulse modulation. Values can be:

• ‘SING’: generates a single pulse

• ‘DOUB’: generates two pulses within one pulse period

double_delay

(Only SMW-K23) Sets the delay from the start of the first pulse to the start of the second pulse.

double_width

(Only SMW-K23) Sets the width of the second pulse.

trigger_mode

period

(Only SMW-K23) Sets the period of the generated pulse, that means the repetition frequency of the internally generated modulation signal.

width

(Only SMW-K23) Sets the width of the generated pulse, that means the pulse length. It must be at least 20ns less than the set pulse period.

delay

(Only SMW-K23) Sets the pulse delay.
