apply_resistance_scaling(channel, range_, buffer_length)[source]

This function is in the header file, but it is not in the manual.

connect_detect(sensors)[source]

This function is in the header file, but it is not in the manual.

device_meta_data(meta_type, operation, format_)[source]

This function is in the header file, but it is not in the manual.

get_common_mode_overflow()[source]

This function is in the header file, but it is not in the manual.

get_string(string_value)[source]

This function is in the header file, but it is not in the manual.

set_channel_led(led_states)[source]

This function is in the header file, but it is not in the manual.

set_pulse_width_qualifier_conditions(conditions, info)[source]

This function sets up the conditions for pulse width qualification, which can be used on its own for pulse width triggering or combined with window triggering to produce more complex triggers. Each call to this function creates a pulse width qualifier equal to the logical AND of the elements of the conditions array. Calling this function multiple times creates the logical OR of multiple AND operations. This AND-OR logic allows you to create any possible Boolean function of the scope’s inputs.

Other settings of the pulse width qualifier are configured by calling set_pulse_width_qualifier_properties().

set_pulse_width_qualifier_properties(direction, lower, upper, pulse_width_type)[source]

This function configures the general properties of the pulse width qualifier.

set_trigger_channel_directions(directions)[source]

This function sets the direction of the trigger for the specified channels.
