utils

Zurich Instruments LabOne Python API Utility Functions.

This module provides basic utility functions to ease the use of the native Python API zhinst-core.

Functions

api_server_version_check(daq)	Check the consistency of the used version in the LabOne stack.
assert_node_changes_to_expected_value(daq, ...)	Polls a node until it has the the expected value.
autoConnect([default_port, api_level])	Try to connect to a Zurich Instruments Data Server (UHF,HF2 only).
autoDetect(daq[, exclude])	Return one of the devices connected to the Data Server.
bw2tc(bandwidth, order)	Convert the demodulator 3 dB bandwidth to its equivalent timeconstant.
bwtc_scaling_factor(order)	Return the appropriate scaling factor for bandwidth to timeconstant.
check_for_sampleloss(timestamps)	Check for sample loss.
convert_awg_waveform(wave1[, wave2, markers])	Convert one or multiple waveforms into the native AWG waveform format.
create_api_session(device_serial, api_level)	Create an API session for the specified device.
default_output_mixer_channel(discovery_props)	Return an instrument's default output mixer channel.
devices(daq)	List of device_id of all devices connected to the Data Server.
disable_everything(daq, device)	Put the device in a known base configuration.
get_default_settings_path(daq)	Return the default path used for settings by the ziDeviceSettings module.
