Methods

Baseline(PinList, string, double, double, string, double, int, PinList, double, string)

Parametric measurement by setting up all force Pins, then measuring all force or optionally different measurement Pins.

[TestMethod]
[Steppable]
[CustomValidation]
public void Baseline(PinList forcePinList, string forceMode, double forceValue, double clampValue, string measureWhat, double measureRange, int sampleSize = 1, PinList measPinList = null, double waitTime = 0, string setup = "")

Parameters

forcePinList PinList: Comma separated list of pin or pin groups representing the DC setup and/or measurement.
forceMode string: Force mode for each pin or pin group.
forceValue double: Force voltage or current for all pins or pin groups.
clampValue double: Clamp voltage or current for all pina or pin groups.
measureWhat string: Measures either voltage or current for all measured pins or pin groups.
measureRange double: Expected voltage or current for all pins or pin groups to set the range.
sampleSize int: Optional. Number of samples to average for all pins or pin groups.
measPinList PinList: Optional. Comma separted list of measurement pins or pin groups, if different from forcePinList.
waitTime double: Optional. Settling time used after pin setup.
setup string: Optional. Setup settting to preconfigure the dib or device.

Test Technique

to be added

Implementation

The Validation section creates the Pins objects, determines force & measure modes and confirms valid combinations.

The PreBody section applies levels and timing from the test instance context. Optionally, applies the specified setup. For all pins specified in the pinList it disconnects any pin electronics, connects the dc path and turns on the gate.

The Body section applies the force condition on all pins, sets the measurement mode and performs the measurement on all pins in parallel after the specified waitTime.

The PostBody section restores the pin electronics connection for digital pins after gating off and disconnecting the dc path. Finally, a parametric datalog is logged.

Platform Specifics

Supports stepping capability for PreBody/Body/PostBody.

Pre Conditions

none

Post Conditions

none

Limitations

support for non-uniform (mixed) instrument types in pinList not yet available
