agb1500_measureP
This function executes a pulsed spot measurement by the specified channel, and
returns the measurement result data, measurement status, and time stamp data.
Syntax ViStatus _VI_FUNC agb1500_measureP(ViSession vi, ViInt32 channel,
ViInt32 mode, ViReal64 range, ViPReal64 value, ViPInt32 status, ViPReal64 time);
Parameters vi Instrument handle returned from agb1500_init( ).
channel Slot number of the slot that installs the SMU to be used. See
Table 2-2.
mode Measurement mode. 1 (current) or 2 (voltage).
range Measurement ranging mode. 0 (auto), positive value (limited
auto), or negative value (fixed range). For the available values,
see Table 2-3.
value Measurement data. Returned data.
status Measurement status. Returned data. See “Status Code” on page
2-14. To disable the status data output, set 0 (NULL pointer)
instead.
time Time stamp data (measurement start time). Returned data. To
disable the time stamp data output, set 0 (NULL pointer)
instead.
