class qcodes.instrument_drivers.tektronix.TektronixDPOTrigger(parent: Instrument, name: str, delayed_trigger: bool = False, **kwargs: Unpack)

Bases: InstrumentChannel

Submodule for trigger setup.

You can trigger with the A (Main) trigger system alone or combine the A (Main) trigger with the B (Delayed) trigger to trigger on sequential events. When using sequential triggering, the A trigger event arms the trigger system, and the B trigger event triggers the instrument when the B trigger conditions are met.

A and B triggers can (and typically do) have separate sources. The B trigger condition is based on a time delay or a specified number of events.

See page75, Using A (Main) and B (Delayed) triggers. https://download.tek.com/manual/MSO70000C-DX-DPO70000C-DX-MSO-DPO7000C-MSO-DPO5000B-Oscilloscope-Quick-Start-User-Manual-071298006.pdf

class qcodes.instrument_drivers.tektronix.TektronixAWG5014(name: str, address: str, *, num_channels: int = 4, **kwargs: Unpack[VisaInstrumentKWArgs])

Bases: VisaInstrument

This is the QCoDeS driver for the Tektronix AWG5014 Arbitrary Waveform Generator.

The driver makes some assumptions on the settings of the instrument:

• The output channels are always in Amplitude/Offset mode

• The output markers are always in High/Low mode

Todo

• Implement support for cable transfer function compensation

• Implement more instrument functionality in the driver

• Remove double functionality

• Remove inconsistensies between the name of a parameter and the name of the same variable in the tektronix manual

In the future, we should consider the following:

• Removing test_send??

• That sequence element (SQEL) parameter functions exist but no corresponding parameters.

Initializes the AWG5014.

Parameters:

• name – name of the instrument

• address – GPIB or ethernet address as used by VISA

• num_channels – number of channels on the device

set_sqel_event_target_index(element_no: int, index: int) → None

This command sets the target index for the sequencer’s event jump operation. Note that this will take effect only when the event jump target type is set to INDEX.

If you do not wish to send waveforms to channels 1 and 2, use the channels parameter.

• m1s – A list of marker 1’s. The list should be filled like so: [[elem1m1ch1, elem2m1ch1, …], [elem1m1ch2, elem2m1ch2], …] Each marker should be a numpy array containing only 0’s and 1’s

• m2s – A list of marker 2’s. The list should be filled like so: [[elem1m2ch1, elem2m2ch1, …], [elem1m2ch2, elem2m2ch2], …] Each marker should be a numpy array containing only 0’s and 1’s

• nreps – List of integers specifying the no. of repetions per sequence element. Allowed values: 0 to 65536. O corresponds to Infinite repetions.

• trig_waits – List of len(segments) of integers specifying the trigger wait state of each sequence element. Allowed values: 0 (OFF) or 1 (ON).

• goto_states – List of len(segments) of integers specifying the goto state of each sequence element. Allowed values: 0 to 65536 (0 means next)

• jump_tos – List of len(segments) of integers specifying the logic jump state for each sequence element. Allowed values: 0 (OFF) or 1 (ON).

• channels – List of channels to send the waveforms to. Example: [1, 3, 2]

• preservechannelsettings – If True, the current channel settings are found from the parameter history and added to the .awg file. Else, channel settings are not written in the file and will be reset to factory default when the file is loaded. Default: True.

• filename – The full path of the .awg-file. Should end with the .awg extension. Default: ‘customawgfile.awg’

get_error() → str

This function retrieves and returns data from the error and event queues.

Returns:

String containing the error/event number, the error/event description.

delete_all_waveforms_from_list() → None

Delete all user-defined waveforms in the list in a single action. Note that there is no “UNDO” action once the waveforms are deleted. Use caution before issuing this command.

If the deleted waveform(s) is (are) currently loaded into waveform memory, it (they) is (are) unloaded. If the RUN state of the instrument is ON, the state is turned OFF. If the channel is on, it will be switched off.

get_filenames() → str

Duplicate of self.get_folder_contents

send_DC_pulse(DC_channel_number: int, set_level: float, length: float) → None

Sets the DC level on the specified channel, waits a while and then resets it to what it was before.

Note: Make sure that the output DC state is ON.

Parameters:

• DC_channel_number (int) – The channel number (1-4).

• set_level (float) – The voltage level to set to (V).

• length (float) – The time to wait before resetting (s).

is_awg_ready() → bool

Assert if the AWG is ready.

Returns:

True, irrespective of anything.

send_waveform_to_list(w: ndarray, m1: ndarray, m2: ndarray, wfmname: str) → None

Send a single complete waveform directly to the “User defined” waveform list (prepend it). The data type of the input arrays is unimportant, but the marker arrays must contain only 1’s and 0’s.

Parameters:

• w – The waveform

• m1 – Marker1

• m2 – Marker2

• wfmname – waveform name

Raises:

• Exception – if the lengths of w, m1, and m2 don’t match

• TypeError – if the waveform contains values outside (-1, 1)

• TypeError – if the markers contain values that are not 0 or 1

clear_message_queue(verbose: bool = False) → None

Function to clear up (flush) the VISA message queue of the AWG instrument. Reads all messages in the queue.

Parameters:

verbose – If True, the read messages are printed. Default: False.

Bases: Parameter

A measurement parameter does not only return the instantaneous value of a measurement, but can also return some statistics. The accumulation time over which these statistics are gathered can be controlled through the ‘time_constant’ parameter on the submodule ‘TektronixDPOMeasurementStatistics’. Here we also find the method ‘reset’ to reset the values over which the statistics are gathered.

Methods:

mean()
max()
min()
stdev()
get_raw()	get_raw is called to perform the actual data acquisition from the instrument.
set_raw(value)	set_raw is called to perform the actual setting of a parameter on the instrument.

mean() → float

max() → float

min() → float

stdev() → float

get_raw() → float

get_raw is called to perform the actual data acquisition from the instrument. This method should either be overwritten to perform the desired operation or alternatively for Parameter a suitable method is automatically generated if get_cmd is supplied to the parameter constructor. The method is automatically wrapped to provide a get method on the parameter instance.

set_raw(value: Any) → None

set_raw is called to perform the actual setting of a parameter on the instrument. This method should either be overwritten to perform the desired operation or alternatively for Parameter a suitable method is automatically generated if set_cmd is supplied to the parameter constructor. The method is automatically wrapped to provide a set method on the parameter instance.
