PXI-4110 Operating Guidelines

Refer to the following sections for information about PXI-4110 features and guidelines for operating the PXI-4110.

Sourcing and Sinking
The terms sourcing and sinking describe power flow into and out of a device, respectively. The PXI-4110 is capable of only sourcing power and not sinking power.
Output Impedance
NI power supplies and SMUs include output amplifiers that drive their outputs through series resistors. The resistors enable the measurement and control of output current. The value of the resistor is larger for low-current ranges and smaller for high-current ranges.
Protection
The output channels and the auxiliary power input of the PXI-4110 are protected against overcurrent, overvoltage, inverse voltage, and overtemperature conditions.
Load Regulation
Load regulation is a measure of the ability of an output channel to remain constant given changes in the load.
Ranges
NI power supplies and SMUs use one or more ranges for voltage and current output, as well as one or more ranges for voltage and current measurement.
Noise
Noise is unwanted signals present on the output channels that can affect devices connected to the output channels.
Resistance Measurements
NI power supplies and SMUs can make resistance measurements because they can both generate and measure test voltages and currents. Because they can operate as precision current sources at high current levels, these devices are well suited to measure low resistance values.
Replacing a Fuse
All of the input and output connections on the PXI-4110 front panel have user-replaceable fuses.
Sourcing and Measuring Terminology
Refer to the following terms when learning more about the features and usage of the PXI-4110:
Calibration
PXI-4110 only supports external calibration.
