Setting DC
Measurement
Parameters
The following example shows how to specify PMU type for the
PMU_IFVM API.
•For pin1 and pin_group2 connected to the Pin PMUs:
PMU_IFVM("pin1, pin_group2");
or
PMU_IFVM("pin1, pin_group2", TM::PPMU);
•For pin1 connected to the High Precision PMU:
PMU_IFVM("pin1", TM::SPMU);
This section describes only the main DC measurement parameters. For all
DC measurement parameters, see the related API of the Test Method
Programming Reference.
Force Current/Voltage
For PPMU or SPMU, you can specify the force current or force voltage
with the iForce and vForce member function of the PMU_IFVM or
PMU_VFIM API. For the DPS, the force voltage is set in a level setup file,
not using the DPS_VFIM API.
Limit Values
limits(): To use limit values that are set in the Parameter dialog box,
specify the test name for this parameter.
Settling Time
settling(): (For PMU only) Settling time specifies the time interval
between the PMU being programmed and the measurement being
performed.
Connection Mode
mode(): (For PMU only) This mode specifies the relay control pattern
and how to test multiple pins as shown bellow. You must specify a mode
for the measurement.
a
Mode AC Relay Control
TP close -> close -> close
NP close -> open -> close
TS close -> close -> close
NS close -> open -> close
NR performs a measurement without relay control
b
SP Performs a continuity test
(single polarity)
b
BP Performs a continuity test
(both polarities)
a
This column shows the relay status at the following situations
(before measurement) -> (during measurement) -> (after measurement)
