mpylab.device.nw_rs_zvl_virtual module

Virtual R&S ZVL driver used for UI and workflow testing without hardware.

class mpylab.device.nw_rs_zvl_virtual.NETWORKANALYZER(SearchPaths=None)

Bases: NETWORKANALYZER

In-memory simulation of the ZVL network analyzer.

Parameters:

SearchPaths (sequence of path-like, optional) – Directories searched for referenced configuration files.

GetDescription()

Return the virtual instrument identification without bus access.

Returns:

Status code and identification string.

Return type:

tuple of (int, str)

Init(ini=None, channel=None, ignore_bus=None)

Initialize the virtual analyzer without opening a bus.

Parameters:

• ini (path-like or file-like, optional) – INI configuration source.

• channel (int, optional) – One-based configuration channel number. Defaults to channel 1.

Returns:

Zero on success, otherwise the initialization error status.

Return type:

int

query(cmd, tmpl=None)

Write a virtual SCPI query and return its response.

Parameters:

• cmd (str) – Query command to process.

• tmpl (str, optional) – Regular expression used to parse named response fields.

Returns:

Raw or parsed response.

Return type:

str or dict

read(tmpl=None)

Return or parse the last virtual SCPI response.

Parameters:

tmpl (str, optional) – Regular expression used to parse named response fields.

Returns:

Raw response without tmpl, otherwise the matched named fields.

Return type:

str or dict

write(cmd)

Parameters:

cmd (str) – Command to process.

Returns:

Zero on success.

Return type:

int

mpylab.device.nw_rs_zvl_virtual.main()

Run a small local smoke test against the virtual ZVL driver.
