 The default unit of the return value is rad.
 After the phase deviation step is set, you can rotate the knob to modify the
phase deviation at the current step. At this point, you can query or set the
phase deviation using the [:SOURce]:PM[:DEViation] command.
Return Format The query returns the phase deviation step. For example, 1.000000.
