Tektronix Oscilloscopes¶

Driver module for Tektronix oscilloscopes. Currently supports

class instrumental.drivers.scopes.tektronix.MSO_DPO_4000(name=None, visa_inst=None)¶: A Tektronix MSO/DPO 4000 series oscilloscope.

class instrumental.drivers.scopes.tektronix.TDS_3000(name=None, visa_inst=None)¶: A Tektronix TDS 3000 series oscilloscope.

class instrumental.drivers.scopes.tektronix.TekScope(name=None, visa_inst=None)¶

A base class for Tektronix scopes. Supports at least TDS 3000 series as well as MSO/DPO 4000 series scopes.

__init__(name=None, visa_inst=None)¶: Create a scope object that has the given VISA name name and connect to it. You can find available instrument names using the VISA Instrument Manager.

are_measurement_stats_on()¶: Returns whether measurement statistics are currently enabled

enable_measurement_stats(enable=True)¶

Enables measurement statistics.

When enabled, measurement statistics are kept track of, including ‘mean’, ‘stddev’, ‘minimum’, ‘maximum’, and ‘nsamps’.

Parameters:	enable (bool) – Whether measurement statistics should be enabled

get_data(channel=1)¶

Retrieve a trace from the scope.

Pulls data from channel channel and returns it as a tuple (t,y) of unitful arrays.

Parameters:	channel (int, optional) – Channel number to pull trace from. Defaults to channel 1.
Returns:	t, y – Unitful arrays of data from the scope. `t` is in seconds, while `y` is in volts.
Return type:	pint.Quantity arrays

read_measurement_stats(num)¶

Read the value and statistics of a measurement.

Parameters:	num (int) – Number of the measurement to read from, from 1-4
Returns:	stats – Dictionary of measurement statistics. Includes value, mean, stddev, minimum, maximum, and nsamps.
Return type:	dict

read_measurement_value(num)¶

Read the value of a measurement.

Parameters:	num (int) – Number of the measurement to read from, from 1-4
Returns:	value – Value of the measurement
Return type:	pint.Quantity

set_math_function(expr)¶

Set the expression used by the MATH channel.

Parameters:	expr (str) – a string representing the MATH expression, using channel variables CH1, CH2, etc. eg. ‘CH1/CH2+CH3’

set_measurement_nsamps(nsamps)¶

Sets the number of samples used to compute measurements.

Parameters:	nsamps (int) – Number of samples used to compute measurements

set_measurement_params(num, mtype, channel)¶

Set the parameters for a measurement.

Parameters:	num (int) – Measurement number to set, from 1-4. mtype (str) – Type of the measurement, e.g. ‘amplitude’ channel (int) – Number of the channel to measure.
