Section 7: SCPI command reference
Before the calculation, start the trigger model to take 10
readings.
The first CALC2:IMM? returns reading, units, timestamp
and reading number for MIN and MAX:
5.986128E+00V,06/25/2013

09:39:30.7283,0001RNDG#
The second CALC2:IMM? only returns reading and units
for MIN, MAX, MEAN, PKPK and SDEV:
5.986128E+00V,5.987489E+00V,5.986298E+00V,1.360
893E-03V,4.204334E-04V
CALC2:DATA? returns reading and units for MAX and
SDEV: 5.987489E+00V,4.204334E-04V
