Matlab functions for OWON VDS6000 USB oscilloscopes - SCPI commands

OWON VDS6000 USB Oscilloscope

Matlab functions to setup and read data from OWON VDS6102 USB oscilloscopes using SCPI commands.

To create the VISA-Session with custom configuration

os = setup_owon_scope()

Returns os.obj : the instrument object. os.settings : the setting structure

Once created, you can modify os.settings values and configure the instrument with the new values

os = setup_owon_scope(os)

To check the configuration:

current_settings = check_owon_config(os);

To get ADC data from the instrument:

[data, ~] = get_owon_data(os)

sample_rate = data.sample_rate

waveform_points = data.points

Example of the waveforms captured from both channels without considering their respective vertical offset

CH1: Test signal with Probe. 3.3V Squarte signal at 1kHz

CH2: 2V Ramp signal at 2kHz from function generatior (MULTI)

owon-vds6000's Issues

VI_ERROR_INP_PROT_VIOL

Error ocurred after FETC?

Visa Error: A binblock is not available to read in get_owon_data

Empty data points in the middle of the pulling operation. FETC? command could take an unexpected longer time.
Matlab could try to binblockread while the instrument is still downloading data

Trigger command issues

Trigger sweep at Normal is not working. Got Empty Data packet.

Trigger level is also not setting up as requested in the setup - Probably another function setting is resetting the trigger level.
