skippylab.scpi.commands.add_arg(cmd, arg)[source]

Add an argument to a command string. Concat the two.

Parameters:
  • cmd (str) – The base command
  • arg (str) – An argument
Returns:

str
skippylab.scpi.commands.clean_response(response)[source]

Remove some EOL remainders from the resulting scope response

Parameters:response (str) – response from the scope
Returns:str
skippylab.scpi.commands.concat(*cmd)[source]

Combine several commands

Parameters:cmd – list of commands
Returns:str
skippylab.scpi.commands.histbox_coordinates(left, top, right, bottom)[source]

Create a string for the box coordinates for the histogram set up by the scope itself. The result can be send to the scope to set the box.

Parameters:
  • left (int) –
  • top (int) –
  • right (int) –
  • bottom (int) –
Returns:

str
skippylab.scpi.commands.parse_curve_data(header, curve)[source]

Make sense out of that what is returned by CURVE. This works only if the scope is set to return the data in ASCII, not binary.

Parameters:
  • header (dict) – a parsed header
  • curv (str) – returned by CURVE?
Returns:

np.ndarray xs, np.ndarray values
Return type:

tuple
