Explanation  [,<src>[,<src>]] sets the source of the parameter to be measured.
 When <item> is PERiod, FREQuency, PWIDth, NWIDth, PDUTy, NDUTy, RDELay,
FDELay, RPHase, or FPHase, the range of <src> is
{D0|D1|D2|D3|D4|D5|D6|D7|D8|D9|D10|D11|D12|D13|D14|D15|CHANnel1|CHAN
nel2|CHANnel3|CHANnel4|MATH}.
When <item> is any of other measurement parameters, the range of <src> is
{CHANnel1|CHANnel2|CHANnel3|CHANnel4|MATH}.
 If the parameter to be measured only needs a single source (VMAX, VMIN, VPP,
VTOP, VBASe, VAMP, VAVG, VRMS, OVERshoot, MARea, MPARea, PREShoot, PERiod,
FREQuency, RTIMe, FTIMe, PWIDth, NWIDth, PDUTy, NDUTy, TVMAX, TVMIN,
PSLEWrate, NSLEWrate, VUPper, VMID, VLOWer, VARIance, PVRMS, PPULses,
NPULses, PEDGes, and NEDGes), you only need to set a single source. If
[,<src>[,<src>]] is omitted, the source is the one selected by the
:MEASure:SOURce
command by default.
 If the parameter to be measured needs two sources (RDELay, FDELay, RPHase, and
FPHase), the command needs to include two sources; otherwise, the command is
invalid. If [,<src>[,<src>]] is omitted, the sources are the ones selected by
the
:MEASure:SETup:DSA and :MEASure:SETup:DSB or :MEASure:SETup:PSA
and :MEASure:SETup:PSB commands by default.
Return
Format
The query returns the measurement result in scientific notation.
Example
:MEASure:ITEM OVERshoot,CHANnel2 /*Enable the overshoot measurement of CH2*/
:MEASure:ITEM? OVERshoot,CHANnel2 /*The query returns 8.888889e-03*/
