5.4.1 OUTPUT PARAMETERS (cont)
:[SOURce:]IMPEDance:STATE <b>
Enables or disables the optional Programmable Output
Impedance function.
b
= <OFF>, <0> or <ON>, <1>
:[SOURce:]IMPEDance <z>
Sets the value of the optional Programmable Output Impedance.
z
= varies based on the present configuration and operational mode of
the power source.
Use :SOUR:IMPED:LIM:MIN? and :SOUR:IMPED:LIM:MAX? to
determine the available range.
:[SOURce:]IMPEDance:LIMit:MINimum? <min z>
Query: returns the minimum allowable impedance
:[SOURce:]IMPEDance:LIMit:MAXimum? <max z>
Query: returns the maximum allowable impedance
:[SOURce:]IMPEDance:CAL <z1,z2,z3, x1,z4, x2,z5, x3,z6>
Calibrates the optional Programmable Output Impedance function with
values for:

x values are transformer ratios. Relation to unity (1) is assumed. For
a 2.5:1 step-up transformer, the x value is 2.5. For a 0.1:1 step-down
transformer, the x value is .1.
z values are the calibrated impedance value, expressed in ohms.
See para. 4.6.3.1.1 for details on this function.
:[SOURce:]IMPEDance:RESet
Resets Programmable Output Impedance calibration values to the
system defaults.
:[SOURce:]TRANSient:AUTO
<b>
Sets Transient Auto RMS mode.
b
= <OFF>, <0> or <ON>, <1>
See para. 4.6.3.9 for a detailed description.
