:MEASure:AMSource
:MEASure:AMSource <chan>
:MEASure:AMSource?
Sets the source and displays all measurement values of the set source; or queries the
channel source (s) of the all measurement function.
{CHANnel1|CHANnel2|CHANnel3|CHANnel4|OFF}
The query returns CHAN1, CHAN2, CHAN3, CHAN4, MATH1, MATH2, MATH3, MATH4, or
OFF. They are separated by commas.
:MEASure:AMSource CHANnel1,CHANnel3 /*Sets the sources of the all measurement
function to CH1 and CH3.*/
:MEASure:AMSource? /*The query returns CHAN1 and CHAN3.*/
:MEASure:SETup:MAX
:MEASure:SETup:MAX <value>
:MEASure:SETup:MAX?
Sets or queries the threshold level upper limit of the analog channel in auto
measurement.
 When the threshold type is percentage, its range is from 0% to 100%; when the
threshold type is absolute, its range is from -100 mV to 100 mV.
 When the set upper limit is smaller than the current middle value, the middle value
will be automatically reduced, so as to make itself to be smaller than the upper
limit.
The query returns an integer.
:MEASure:SETup:MAX 95 /*Sets the upper limit of the threshold level to 95%.*/
:MEASure:SETup:MAX? /*The query returns 95.*/
:MEASure:SETup:MID
:MEASure:SETup:MID <value>
:MEASure:SETup:MID?
Sets or queries the threshold level middle value of the analog channel in auto
measurement.
 When the threshold type is percentage, its range is from 0% to 100%; when the
threshold type is absolute, its range is from -100 mV to 100 mV.
 The set middle value must be smaller than the currently set upper limit and greater
than the currently set lower limit.
