Connect to the DPO70000 in Python

OSCILLOSCOPES > TEKTRONIX

PROTOCOLS > SCPI

Here is an example Python script that uses Qcodes to connect to a DPO70000 Oscilloscope:

import qcodes as qc
from qcodes.instrument_drivers.tektronix.Tektronix_DPO7000xx import TektronixDPO7000xx


# Connect to the oscilloscope
oscilloscope = TektronixDPO7000xx("oscilloscope", "TCPIP::1.2.3.4::INSTR")


# Print the available channels
print(oscilloscope.channel.names)


# Set the time per division for channel 1
oscilloscope.channel1.scale(0.1)


# Set the trigger type to edge and the source to channel 1
oscilloscope.trigger.type("edge")
oscilloscope.trigger.source("CH1")


# Arm the trigger and wait for a trigger event
oscilloscope.trigger.state(1)
oscilloscope.trigger.wait_for_trigger()


# Get the waveform data from channel 1
waveform = oscilloscope.channel1.waveform()


# Plot the waveform
import matplotlib.pyplot as plt
plt.plot(waveform.trace_axis(), waveform.trace())
plt.xlabel(waveform.trace_axis().label)
plt.ylabel(waveform.trace().label)
plt.show()


# Disconnect from the oscilloscope
oscilloscope.close()

This script connects to the oscilloscope using the IP address “1.2.3.4” (replace with the actual IP address of your oscilloscope). It then sets the time per division for channel 1 to 0.1 seconds and configures the trigger type to edge with the source as channel 1. It arms the trigger and waits for a trigger event. After the trigger event, it retrieves the waveform data from channel 1 and plots it using matplotlib. Finally, it disconnects from the oscilloscope.
