    Programmable output voltage limit (Vclamp). Valid values range from 0 V to -100 V.

    The reverse output bias current maintains accuracy for load voltages within the specified output clamp voltage. At load voltages beyond (more negative than) the specified clamp voltage, the output current bias current is reduced. The output bias current shuts off and reaches zero current typically between 0.5 V and 2.5 V beyond the programmed clamp voltage. The following figure depicts an example of varying output load voltage with the clamp voltage set to -50 V, for three different output bias current settings.

    Contact Check Functions

    The PXIe-4133 supports two methods of contact checking: the Low Voltage Contact Check function and the Contact Check function. The Low Voltage Contact Check more strictly limits the available output voltage and current. This may be important when probing potentially sensitive circuits or structures. The Contact Check function supports higher voltages and currents, which may be desirable when trying to forward bias a diode junction during the contact check.

    Summary of the contact check methods:

    Low Voltage Contact Check

    • Outputs voltage up to 0.5 V between Force_HI and Force_LO
    • Short circuit limited to 650 μA
    • Measures current (0 to 100 μA range) out of Force_HI pin
    • Measures voltage between Sense_HI and Sense_LO pins (remote sense, 4-wire mode)

    Contact Check

    • Outputs current up to 10 mA from Force_HI to Force_LO
    • Voltage clamp programmable up to 5 V between Force_HI and Force_LO
    • Measures current into Force_LO pin
    • Measures voltage across Force pins (local sense, 2-wire mode) or Sense pins (remote sense, 4-wire mode)

    With the Contact Check function, the PXIe-4133 pulses a test current in the same manner as the normal Pulse Current mode, but with the addition of an output voltage clamp. Current is driven out of the Force_HI pin and returns through and is measured at the Force_LO pin. You can read back the voltage either from the local sense (Force_HI and Force_LO, 2-wire mode) or from remote sense (Sense_HI and Sense_LO, 4-wire mode). The voltage clamp is placed between the Force_HI and Force_LO (across the current source) so selecting between local and remote sense has no impact on the current or the output voltage.

    In the Contact Check mode, the current source has a 1 kOhm output impedance, and the voltage clamp has a 50 Ohm impedance. The following figure shows the resulting Current vs Voltage profile with the output current set to 10 mA and voltage clamps set for 1 V to 5 V.

    The low voltage contact check function limits the possible voltage and current to much lower energy levels for validating contact with more sensitive circuits and structures. The Low Voltage contact check applies a small configurable bias voltage (up to 500 mV) between Force_HI and Force_LO. The current that flows out of the Force_HI pin is measured within a range of 0 to 100 μA, and is limited to about 650 μA in case of short circuits.

    Low Voltage Contact Check also reads the voltage between Sense_HI and Sense_LO. Sense_HI and Sense_LO are only used to read voltage; the voltage on the Sense lines does not impact the Force current and voltage. Low Voltage Contact Check does not support Local Sense mode; the voltage between the Force pings is not read back directly.

    In the Low Voltage Contact Check mode, the configurable output voltage has an impedance of about 120 Ohms. There is a 640 μA current limiter with an impedance of 5 kOhm. The following figure shows the resulting Current vs Voltage profile with the output voltage at settings between 50 mV and 500 mV.

    Use the LowVoltageContactCheck() function to perform a Low Voltage Contact Check. Although the short-circuit current limit is set to 600 μA, the current measurement range is only 0 μA to 100 μA. An open circuit reads near zero μA. To tell that contact is made and current is flowing, the device you are contacting must be conducting at least several microamps at the test voltage you select (up to 500 mV).

    Note Setting the trigger source to none produces an immidate trigger.
    Note The abort trigger inhibits pulsing while active. For example, if the abort trigger source is set to PXI_Trig0 and the abort trigger edge is rising, the pulser aborts immediately because PXI trigger lines are disconnected by default. If the pulser is waiting for a start trigger, the abort trigger aborts the wait.

    Rated Voltages

    The PXIe-4133 is intended to measure passive devices, such as diodes, in configurations where voltages are either generated by the PXIe-4133 directly or by currents output from the PXIe-4133 which are driven across a device under test.

    Notice The protection provided by the PXIe-4133 can be impaired if it is used in a manner not described in the user documentation.
    Note The specified values are maximum voltages that the PXIe-4133 outputs and measures back. The user does not apply voltages.

    The maximum voltages and currents that the PXIe-4133 can output to a VCSEL device being tested are:

    This product is rated for Measurement Category I.

    Measurement Category I

    Caution Do not connect the product to signals or use for measurements within Measurement Categories II, III, or IV.
    Attention Ne pas connecter le produit à des signaux dans les catégories de mesure II, III ou IV et ne pas l'utiliser pour effectuer des mesures dans ces catégories.
    Warning Do not connect the product to signals or use for measurements within Measurement Categories II, III, or IV, or for measurements on MAINs circuits or on circuits derived from Overvoltage Category II, III, or IV which may have transient overvoltages above what the product can withstand. The product must not be connected to circuits that have a maximum voltage above the continuous working voltage, relative to earth or to other channels, or this could damage and defeat the insulation. The product can only withstand transients up to the transient overvoltage rating without breakdown or damage to the insulation. An analysis of the working voltages, loop impedances, temporary overvoltages, and transient overvoltages in the system must be conducted prior to making measurements.
    Mise en garde Ne pas connecter le produit à des signaux dans les catégories de mesure II, III ou IV et ne pas l'utiliser pour des mesures dans ces catégories, ou des mesures sur secteur ou sur des circuits dérivés de surtensions de catégorie II, III ou IV pouvant présenter des surtensions transitoires supérieures à ce que le produit peut supporter. Le produit ne doit pas être raccordé à des circuits ayant une tension maximale supérieure à la tension de fonctionnement continu, par rapport à la terre ou à d'autres voies, sous peine d'endommager et de compromettre l'isolation. Le produit peut tomber en panne et son isolation risque d'être endommagée si les tensions transitoires dépassent la surtension transitoire nominale. Une analyse des tensions de fonctionnement, des impédances de boucle, des surtensions temporaires et des surtensions transitoires dans le système doit être effectuée avant de procéder à des mesures.

    Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

    Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.
