IEEE488.2#

Every SCPI interface is based on the IEEE488.2 protocol. This Python implementation separates the protocol into two layers:

IEEE488.2 layer: IEEE488.2 layer that implements the protocol based on the transport layer.
Transport layer: Transport layers responsible for lowest level of communication (e.g. Ethernet or dummy).”

IEEE488.2 layer#

class qblox_instruments.ieee488_2.Ieee488_2(transport: Transport)[source]#

Bases: object

Class that implements the IEEE488.2 interface.

__init__(transport: Transport)[source]#

Creates IEEE488.2 interface object.

Parameters:: transport (Transport) – Transport class responsible for the lowest level of communication (e.g. ethernet).

Transport layer#

class qblox_instruments.ieee488_2.IpTransport(host: str, port: int = 5025, timeout: float = 60.0, snd_buf_size: int = 524288)[source]#

class qblox_instruments.ieee488_2.ClusterDummyTransport(dummy_cfg: Dict[str | int, ClusterType])[source]#

Bases: DummyTransport

Class to replace Cluster device with dummy device to support software stack testing without hardware. The class implements all mandatory, required and Cluster specific SCPI calls. Call reponses are largely artifically constructed to be inline with the call’s functionality (e.g. *IDN? returns valid, but artificial IDN data.) To assist development, the Q1ASM assembler has been completely implemented. Please have a look at the call’s implentation to know what to expect from its response.
