RsInstrument module provides convenient way of communicating with R&S instruments.
Basic Hello-World code:
.. code-block:: python
from RsInstrument import *
instr = RsInstrument('TCPIP::192.168.56.101::hislip0', id_query=True, reset=True)
idn = instr.query_str('*IDN?')
print('Hello, I am: ' + idn)

Version history:
----------------
Version 1.90.0.108 (07.10.2024)
- Changed the minimum Python requirement to 3.7 to avoid SCPI Logger Regex error.
- Fixed VISA Timeout Error generations for NRP sessions.
- Added Instrument Options methods: has_instr_option(), has_instr_option_regex(), has_instr_option_k0(), add_instr_option(), remove_instr_option()
Version 1.82.1.106 (13.06.2024)
- Fixed failing 'import visa' statement for python > 3.10
Version 1.82.0.105 (07.06.2024)
- Changes in ScpiLogger:
- info(), error() - changed the last parameter 'cmd' to optional
- info_bin(), info_list() - changed the order of the last two parameters!!! 'cmd' moved to the end and made optional, to be compatible with 1.61.0
- ContextManager VisaTimeoutSuppressor made more robust in case of exceptions inside the other exceptions.
Version 1.80.0.103 (27.05.2024)
- Core 1.90.0 with more robust _flush_junk_data() that tolerates read timeouts.
- Added Logger.log_info_replacer for customizing the logging info strings.
- Logger info strings 'Write string' and 'Query string' shortened to 'Write' and 'Query'
Version 1.70.0.102 (26.04.2024)
- To all query_str_list_xxx() methods, added non-mandatory parameter 'remove_blank_response'.

.. code-block:: python
# Any Instrument error in the context is ignored
with io.instr_err_suppressor() as supp:
io.write("*RSaT")
if supp.get_errors_occurred():
print("Error(s) suppressed")
# Any Timeout error in the context is ignored
with io.visa_tout_suppressor(500) as supp:
io.write("*IDaN")

The original format is still supported.\r\n - Fixed calling SYST:ERR? even if STB? returned 0.\r\n - Replaced @ni backend with @ivi for resource manager - this is necessary for the future pyvisa version 1.12+.\r\n\r\n Version 1.13.0.63 (09.06.2021)\r\n - Added methods reconnect(), is_connection_active().\r\n\r\n Version 1.12.1.60 (01.06.2021)\r\n - Fixed bug with error checking when events are defined.\r\n\r\n Version 1.12.0.58 (03.05.2021)\r\n - Changes in Core only.\r\n\r\n Version 1.11.0.57 (18.04.2021)\r\n - Added aliases for the write_str... and query_str... methods:\r\n - write() = write_str()\r\n - query() = query_str()\r\n - write_with_opc() = write_str_with_opc()\r\n - query_with_opc() = query_str_with_opc()\r\n\r\n Version 1.9.1.54 (20.01.2021)\r\n - query_opc() got additional non-mandatory parameter 'timeout'.\r\n - Code changes only relevant for the auto-generated drivers.\r\n\r\n Version 1.9.0.52 (29.11.2020)\r\n - Added Thread-locking for sessions. Related new methods: get_lock(), assign_lock(), clear_lock().\r\n - Added read-only property 'resource_name'.\r\n\r\n Version 1.8.4.49 (13.11.2020)\r\n - Changed Authors and copyright.\r\n - Code changes only relevant for the auto-generated drivers.\r\n - Extended Conversions method str_to_str_list() by parameter 'clear_one_empty_item' with default value False.\r\n\r\n Version 1.8.3.46 (09.11.2020)\r\n - Fixed parsing of the instrument errors when an error message contains two double quotes.\r\n\r\n Version 1.8.2.45 (21.10.2020)\r\n - Code changes only relevant for the auto-generated drivers.\r\n - Added 'UND' to the list of float numbers that are represented as NaN.\r\n\r\n Version 1.8.1.41 (11.10.2020)\r\n - Fixed Python 3.8.5+ warnings.\r\n - Extended documentation, added offline installer.\r\n - Filled package's __init__ file with the exposed API. This simplifies the import statement.\r\n\t\r\n Version 1.7.0.37 (01.10.2020)\r\n - Replaced 'import visa' with 'import pyvisa' to remove Python 3.8 pyvisa warnings.\r\n - Added option to set the termination characters for reading and writing. Until now, it was fixed to '\\\\n' (Linefeed). Set it in the constructor 'options' string: DriverSetup=(TerminationCharacter = '\\\\r'). Default value is still '\\\\n'.\r\n - Added static method RsInstrument.assert_minimum_version() raising assertion exception if the RsInstrument version does not fulfill at minimum the entered version.\r\n - Added 'Hameg' to the list of supported instruments.\r\n\r\n Version 1.6.0.32 (21.09.2020)\r\n - Added documentation on readthedocs.org.\r\n - Code changes only relevant for the auto-generated drivers.\r\n\r\n Version 1.5.0.30 (17.09.2020)\r\n - Added recognition of RsVisa library location for linux when using options string 'SelectVisa=rs'.\r\n - Fixed bug in reading binary data 16 bit.\r\n\r\n Version 1.4.0.29 (04.09.2020)\r\n - Fixed error for instruments that do not support \\*OPT? query.\r\n\r\n Version 1.3.0.28 (18.08.2020)\r\n - Implemented SocketIO plugin which allows the remote-control without any VISA installation.\r\n - Implemented finding resources as a static method of the RsInstrument class.\r\n\r\n Version 1.2.0.25 (03.08.2020)\r\n - Fixed reading of long strings for NRP-Zxx sessions.\r\n\r\n Version 1.1.0.24 (16.06.2020)\r\n - Fixed simulation mode switching.\r\n - Added Repeated capability.\r\n\r\n Version 1.0.0.21\r\n - First released version.\r\n",
