Seg_Arb_Sequence; Seg_Arb_Waveform; Setmode (Llec) - Keithley 4200A-SCS Reference Manual

Model 4200A-SCS Parameter Analyzer Reference Manual
Example
seg_arb_waveform(PMU1, 1, 3, Seq_Num, Seq_Loop_Count);
This function configures channel 1 of the PMU for a single three-sequence Segment Arb
shown in the figure in the Details). This example assumes that the three sequences shown in the figure
have already been defined by the seg_arb_sequence command.
The arrays for the waveform are:
int Seq_Num[3] = {2, 3, 1};
double Seq_Loop_Count[3] = {1, 1, 2};

setmode (LLEC)

This command sets the number of iterations for load-line effect compensation (LLEC) for the PMU.
Usage
int setmode(int instr_id, long modifier, double value);
instr_id
modifier

Parameters to set maximum iterations tolerance windows:
•
KI_PXU_LLC_MAX_ITERATIONS: Maximum iterations
•
KI_PXU_CH1_LLC_TOLERANCE: Acceptance window (Ch 1)
•
KI_PXU_CH2_LLC_TOLERANCE: Acceptance window (Ch 2)
•
KI_PXU_CH1_LLC_OFFSET: LLEC Offset (Ch 1)
•
KI_PXU_CH2_LLC_OFFSET: LLEC Offset (Ch 2)
Values to set maximum iterations and tolerance window:
•
Maximum number of iterations: 1 to 1000; typical setting is 20 to 30 iterations
•
Acceptance window: 0.0001 to 1 (0.01% to 100%); typical range is 0.001 to
0.01 (0.1% to 1%). The typical value is 0.003 (0.3%).
•
Offset value: Value is in volts
