PXIe-4162 Operating Guidelines

Refer to the following sections for information about PXIe-4162 features and guidelines for operating the PXIe-4162.

Sourcing and Sinking
The terms sourcing and sinking describe power flow into and out of a device, respectively.
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.
Overload Protection (OLP)
The PXIe-4162 is protected against overcurrent (OCP) conditions and overvoltage (OVP) 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 the following:
SourceAdapt Custom Transient Response Ranges
The PXIe-4162 supports SourceAdapt custom transient response, which allows you to set compensation parameters to fine-tune the transient response of a channel for your specific application.
Noise
Noise is unwanted signals present on the output channels that can affect devices connected to the output channels.
Power Measurements
Each channel of the PXIe-4162 has two synchronized ADCs that measure voltage and current. You can use NI-DCPower to measure power flowing to or from the PXIe-4162.
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.
Merged Channels
Merging channels allows multiple channels of a single SMU to work in unison. When you connect the channels in parallel at the destination, you can use your instrument for applications that require a higher current output than any single independent channel of the SMU.
Signal Routing
You can use the PXI Express trigger bus to send and receive events and triggers.
Sourcing and Measuring Terminology
Refer to the following terms when learning more about the features and usage of the PXIe-4162:
Calibration
SMUs support two types of calibration: external calibration and self-calibration.
