class scan.fscan¶

N-dimensional scan along user defined paths. The motion path for each motor is defined through the evaluation of a user-supplied function that is evaluated as a function of the independent variables. -independent variables are supplied through the indepvar string. The syntax for indepvar is “x=expresion1,y=expresion2,…” -If no indep vars need to be defined, write “!” or “*” or “None” -motion path for motor is generated by evaluating the corresponding function ‘func’ -Count time is given by integ_time. If integ_time is a scalar, then the same integ_time is used for all points. If it evaluates as an array (with same length as the paths), fscan will assign a different integration time to each acquisition point. -If integ_time is positive, it specifies seconds and if negative, specifies monitor counts.

IMPORTANT Notes: -no spaces are allowed in the indepvar string. -all funcs must evaluate to the same number of points

Warning

use with extreme care! Accidentally reloading a system module or an installed python module may lead to unpredictable behavior

Warning

Prior to the Sardana version 1.6.0 this macro was successfully reloading python libraries located in the MacroPath. The MacroPath is not a correct place to locate your python libraries. They may be successfully loaded on the MacroServer startup, but this can not be guaranteed. In order to use python libraries within your macro code, locate them in either of valid system PYTHONPATH or MacroServer’s PythonPath property (of the host where MacroServer runs). In order to achieve the previous behavior, just configure the the same directory in both system PYTHONPATH (or MacroServer’s PythonPath) and MacroPath.

Note

if python module is used by any macro, don’t forget to reload the corresponding macros afterward so the changes take effect.
