● Channels’ Input Resistive load options - GtDio6xSetSenseLoadResistance function.
With independent high and low commutating voltages, the source and sink currents each have their own threshold voltage. If the voltage on the input, when the load is activated, is between the two commutating voltages, the load will remain in a high impedance state. The input resistive load is useful in applications with very low DUT output swings (where a traditional active load will not switch on and off completely or quickly) and also as a means of forcing the DUT to a known voltage when the DUT is in HiZ. NOTE: The source and sink currents should be programmed to 0 during normal operation of the resistive load. When the resistive load is placed in HiZ (GTDIO6X_RESISTIVE_LOAD_OPEN) it maintains a low leakage current when the input voltage is between the supply rails. Channels input pull-up and pull-down resistive loads can be read back and set dynamically at any time even while the DIO is running mode.
