Identifying the Issue
- Ensure that your Tektronix oscilloscope is up-to-date with the latest firmware, which can be checked and downloaded from the Tektronix official website.
- Verify if the input signal is connected correctly and check if the probes or BNC cables are in proper working condition.
- Ensure that the oscilloscope's settings correlate with the signal expected (e.g., voltage level, time base, trigger settings).
- Check screen brightness and adjust if necessary to ensure optimum visibility.
Adjusting Display and Settings
- Reset the oscilloscope to factory default settings if you're encountering consistent issues. This can often resolve hidden configuration problems.
- Utilize the "Auto Setup" feature to automatically adjust settings for the detected signal, providing a quick reference to see if the issue is with the display or the signal source.
- Adjust the horizontal and vertical controls to properly scale the waveform within the grid for better readability.
Troubleshooting Signal Issues Programmatically
- If you're accessing the oscilloscope programmatically, confirm that you're invoking the correct commands for data acquisition.
- Review your application logic to ensure synchronization between querying and reading back waveform data.
- Ensure that data parsing from acquisition output is correctly formatted, as improper handling can lead to display errors.
Example Code Snippet:
import visa
def fetch_waveform_data():
rm = visa.ResourceManager()
oscilloscope = rm.open_resource('TCPIP0::192.168.0.12::inst0::INSTR')
# Reset the device
oscilloscope.write('*RST')
# Acquire waveform
oscilloscope.write('DATA:SOURCE CH1')
oscilloscope.write('DATA:WIDTH 1')
oscilloscope.write('DATA:ENC ASCII')
raw_data = oscilloscope.query('CURVE?')
# Process waveform data here
return raw_data
