Refer to the following figure and tables for information about the PXI-5406 front panel connectors and LEDs:
Table 1.
PXI-5406 Signal Descriptions
Signal |
Connector Type |
Access |
Description |
CH 0 |
BNC |
Output |
Generates waveforms from an analog output terminal. |
REF IN |
Input |
Accepts an external PLL Reference Clock and can phase-lock the internal Sample Timebase Clock to the external Reference Clock. |
SYNC OUT/PFI 0 |
Input/Output |
Provides a TTL-level output of the waveform generation or accepts a trigger input from an external source that can start or step through waveform generation or route signals from several clock, event, and trigger sources. |
PFI 1 |
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. |
Table 2.
PXI-5406 ACCESS LED Indicators
The ACCESS LED indicates basic hardware status.
LED Color |
Indication |
No color (off) |
The PXI-5406 is not yet functional, or the PXI-5406 has detected a problem with a power rail. |
Amber |
The PXI-5406 is being accessed. |
Green |
The PXI-5406 is ready to be programmed by NI-FGEN. |
Table 3.
PXI-5406 ACTIVE LED Indicators
The ACTIVE LED indicates the
PXI-5406 hardware state.
LED Color |
Indication |
No color (off) |
The PXI-5406 is not generating. |
Amber |
The PXI-5406 is armed and waiting for a trigger. |
Green |
The PXI-5406 has received a trigger and is generating a waveform. |
Red |
The PXI-5406 has detected an error. NI-FGEN must access the PXI-5406 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 PXI-5406 has detected an unlocked condition on a previously locked PLL. A PLL that is unlocked while in reset does not show an error.
-
The PXI-5406 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]
