    Abort Trigger Aborts the pulsing within ≤7 µs upon receiving the falling edge. None, PXI trigger lines (PXI_Trig0-7), PFI0, PFI1 None
    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:

    Specification Value
    Forward Bias +10 A and +15 Vpk
    Reverse Bias -100 µA and -100 Vpk

    Measurement Category

    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.
