ScopeDriverBase

class ScopeDriverBase

Bases: ABC

Vendor scope driver contract. Concrete drivers compose a transport (typically VisaDriver).

Channels are 1-indexed analog input numbers throughout — the wrapper instrument (InstroScope) is responsible for range-checking against the declared num_channels.

Methods

check_errors	Drain the vendor's error queue; raise RuntimeError if any error is pending.
close	Close the underlying transport.
digitize	Arm a single acquisition and block until the trigger fires and the capture completes.
fetch_waveform	Fetch the most recently acquired waveform from channel.
force_trigger	Force a trigger event immediately, regardless of the configured conditions.
get_acquisition_mode	Read back the current acquisition mode.
get_acquisition_state	Read back the acquisition run state (RUNNING / STOPPED).
get_average_count	Read back the waveforms-to-average count.
get_coupling	Read back input coupling on channel.
get_horizontal_scale	Read back the timebase (seconds/div).
get_probe_attenuation	Read back channel's probe attenuation ratio.
get_sample_rate	Read back the current sample rate (samples per second).
get_trigger_status	Read back the trigger status (ARMED / READY / TRIGGERED / …).
get_vertical_offset	Read back channel's vertical offset (volts).
get_vertical_scale	Read back channel's vertical scale (V/div).
load_settings	Recall a scope setup from name.
measure	Read a built-in measurement (VPP, VMAX, VMIN, VAVG, VRMS, …) on channel.
open	Open the underlying transport.
run	Start continuous (free-running) acquisition.
save_screenshot	Capture a screenshot.
save_settings	Save the current scope setup.
set_acquisition_mode	Set the acquisition mode.
set_average_count	Set the number of waveforms to average.
set_coupling	Set AC/DC input coupling on channel.
set_horizontal_scale	Set the timebase to seconds_per_div.
set_probe_attenuation	Set channel's probe attenuation ratio (e.g. 1, 10, 100, 1000).
set_trigger_level	Set the trigger threshold to level (volts).
set_trigger_mode	Set the trigger sweep mode (AUTO / NORMAL).
set_trigger_slope	Set the trigger edge slope (RISING / FALLING / EITHER).
set_trigger_source	Set the trigger source to analog channel.
set_trigger_type	Set the trigger type (EDGE, PULSE, …).
set_vertical_offset	Set channel's vertical offset to offset (volts).
set_vertical_scale	Set channel's vertical scale to volts_per_div (V/div).
setup_measurement	Ensure a measurement slot exists for measurement_type/channel before the scope triggers.
single	Arm a single-shot acquisition.
stop	Stop acquisition.
