Driver Functions
agb1500_startMeasure
For SMU: 1 (current) or 2 (voltage).
For MFCMU: 1 to 402. See Table 2-6.
range[ ] Measurement ranging mode.
For SMU: 0 (auto), positive value (limited auto), or negative
value (fixed range). See Table 2-3.
For MFCMU: 0 (auto) or positive value (fixed range). See
Table 2-7.
source Enables or disables source data output. 0 (disable) or 1 (enable).
For meas_type=9, 14, and 15, enter 0 (zero). Source data output
is not available for these measurement types.
timestamp Enables or disables time stamp data output. Time stamp data is
the measurement start time. 0 (disable) or 1 (enable).
For meas_type=9, 14, and 15, enter 0 (zero). Time stamp data
output is not available for these measurement types.
monitor Enables or disables MFCMU monitor data output. 0 (disable) or
1 (enable). If monitor=1, the MFCMU AC output level monitor
data and DC bias monitor data will be returned.
This parameter is available only for meas_type=17 and 18. For
the other measurement types, enter 0 (zero).

ViInt32 type = 3; /* pulsed spot measurement */
ViInt32 mode[2]; /* measurement mode */
