This is part 5 in our ongoing series about the National Instruments SCXI platform. Part 5 will discuss the different types of SCXI Chassis.
If you currently have a test system with PXI products manufactured by National Instruments, then you should buy spares today.
The National Instruments E Series is a Legacy Series which includes PCI and PXI Multifunction DAQ Devices. The E Series National Instruments devices have as many as 64 analog input channels, two counters, eight or 32 lines of digital input/output, and a maximum of two analog output channels. The E Series devices can be calibrated internally or externally. The self-calibration or internal calibration alters the instrument relative to an extremely precise and steady internal reference on the device. Self-calibration is recommended when environmental settings vary greatly. Self-calibration can be initiated by utilizing the self-calibrate function or VI that comes with the driver software. On the other hand, external calibration alters the instrument relative to a traceable, extremely precise calibration standard. It is suggested to calibrate the instrument at a minimum for the duration specified in the E Series User Manual.
