Refer to the following figure and tables for information about the PXIe-5450 front panel connectors and LEDs:
Table 1.
PXIe-5450 Signal Descriptions
Signal |
Connector Type |
Access |
Description |
CLK IN |
SMA |
Input |
Accepts an external clock that can be used as a Reference Clock, a Sample Clock, or a Sample Timebase Clock. |
CLK OUT |
Output |
Generates a clock signal that can be shared by other devices. |
PFI 0 |
SMB |
Input/Output |
Accepts a trigger from an external source and can start or step through waveform generation or route signals from several clock, event, and trigger sources. |
PFI 1 |
CH 0+/I+ |
SMA |
Output |
Provides a differential waveform output for channel 0. |
CH 0-/I- |
Provides a complementary differential waveform output for channel 0. |
CH 1+/Q+ |
Provides a differential waveform output for channel 1. |
CH 1-/Q- |
Provides a complementary differential waveform output for channel 1. |

PXIe-5450 ACCESS LED Indicators
The ACCESS LED indicates basic hardware status.
LED Color |
Indication |
No color (off) |
The PXIe-5450 is not yet functional, or the PXIe-5450 has detected a problem with a power rail. |
Amber |
The PXIe-5450 is being accessed. |
Green |
The PXIe-5450 is ready to be programmed by NI-FGEN. |
Table 3.
PXIe-5450 ACTIVE LED Indicators
The ACTIVE LED indicates the
PXIe-5450 hardware state.
LED Color |
Indication |
No color (off) |
The PXIe-5450 is not generating. |
Amber |
The PXIe-5450 is armed and waiting for a trigger. |
Green |
The PXIe-5450 has received a trigger and is generating a waveform. |
Red |
The PXIe-5450 has detected an error. NI-FGEN must access the PXIe-5450 to determine the cause of the error. The LED remains red until the error condition is removed. Example errors include the following:
-
Phase-locked loop (PLL) unlocked: The PXIe-5450 has detected an unlocked condition on a previously locked PLL. A PLL that is unlocked while in reset does not show an error.
-
The PXIe-5450 has powered down because the internal temperature exceeded the maximum limit. The over-temperature condition must be corrected and the hardware reset. To reset the hardware, call niFgen Reset Device or niFgen_ResetDevice, or perform a device reset in MAX.[1]
