1 The ambient temperature of a PXI system is defined as the temperature at the chassis fan inlet (air intake).
2 For increased capability, NI recommends installing the PXIe-4151 in a chassis with slot cooling capacity ≥58 W.
3 Power limit defined by voltage measured between HI and LO terminals.
4 Refer to the Remote Sense and Load Regulation sections for additional accuracy derating and conditions.
5 Temperature coefficient applies beyond 23 °C ± 5 °C ambient within ± 5 °C of Tcal.
6 Tcal is the internal device temperature recorded by the PXIe-4151 at the completion of the last self-calibration.
7 Refer to the Remote Sense and Load Regulation sections for additional accuracy derating and conditions.
8 Temperature coefficient applies beyond 23 °C ± 5 °C ambient within ± 5 °C of Tcal.
9 Tcal is the internal device temperature recorded by the PXIe-4151 at the completion of the last self-calibration.
10 10 Hz to 20 MHZ bandwidth, measured with 1 µF load capacitance at the end of 1 m shielded cable. PXIe-4151 configured for normal transient response.
11 Measured between HI and LO terminals at the module output connector.
12 Channel I/O pins include the HI, LO, HI Sense and LO Sense terminals. The Shield GND terminals of the output connector are connected to chassis ground and not considered channel I/O pins.
13 Channel I/O pins include the HI, LO, HI Sense and LO Sense terminals. The Shield GND terminals of the output connector are connected to chassis ground and not considered channel I/O pins.
14 When sourcing while measuring, both the Source Delay and Aperture Time affect the sampling rate. When taking a measure record, only the Aperture Time affects the sampling rate.
15 As the Source Delay is adjusted, or if advanced sequencing is used, maximum update rates vary.
16 Pulse widths and logic levels are compliant with PXI Express Hardware Specification Revision 1.0 ECN 1.
17 Input triggers can come from any source (PXI trigger or software trigger) and be exported to any PXI trigger line. This allows for easier multi-board synchronization regardless of the trigger source.
18 As the Source Delay is adjusted, or if advanced sequencing is used, maximum update rates vary.
19 As the Source Delay is adjusted, or if advanced sequencing is used, maximum update rates vary.
20 Not all chassis can achieve this ambient temperature range. Refer to PXI chassis specifications to determine the ambient temperature ranges your chassis can achieve.
21 Maximum ambient temperature deratings apply when operating the 25 A range above certain current levels. Refer to the Instrument Capabilities section for additional details.
