Getting Started
The NI PXIe-4300 provides eight, simultaneous sampled, analog input channels, each with
channel-to-channel and channel-to-earth isolation. The PXIe-4300 has a 10 V maximum
measurement range that can be expanded to 300 V when using a TB-4300B. The PXIe-4300 can
be used to measure current when using a TB-4300C, which provides 50 Ω resistors between the
AI+ and AI- terminals to convert current to voltage for current measurements. Each channel of
the NI PXIe-4300 has a 16-bit ADC with three programmable filter settings and four gain
settings. Two input PFI lines are available on the module for triggering.
Installation
Refer to the NI PXIe-4300 and TB-4300/B/C User Guide and Terminal Block Specifications for
step-by-step software and hardware installation instructions.
Module Specifications
Refer to the NI PXIe-4300 Device Specifications document for module specifications.
Module Accessories and Cables
Refer to the NI PXIe-4300 and TB-4300/B/C User Guide and Terminal Block Specifications for
information about supported accessories and cables.
Module Self-Calibration
Self-calibration measures the onboard reference voltage of the module and adjusts the
self-calibration constants to account for any errors caused by short-term fluctuations in the
environment.
NI recommends that you self-calibrate the NI PXIe-4300 module after installation and whenever
the ambient temperature changes. Self-calibration should be performed after the module has
warmed up for the recommended time period. Refer to the NI PXIe-4300 Device Specifications
for the module warm-up time and self-calibration conditions.
