The National Instruments PXI-5404 is a 100 MHz frequency Clocking Applications  
generator packaged in 1-slot PXI module. It generates sine and clock  
outputs simultaneously at up to 100 MHz with 1.07 µHz resolution.  
By using direct digital synthesis (DDS) and precise phase-lock loop  
circuitry, the PXI-5404 generates stable, accurate sine and clock  
outputs of which you can programmatically adjust the amplitude,  
frequency, and phase of the sine and clock outputs as well as the  
duty cycle of the clock output.  
With the simultaneous sine and clock  
outputs, you can employ coherent  
clocking to reduce the test time of your  
device under test (DUT) and eliminate  
the need for antialias filtering. Because

The PXI-5404 is a versatile, cost-effective, sine wave generator  
analog stimulus and the sample clock, there is no need for window-  
weighting functions in your FFTs for spectral analysis, thus reducing  
the need to sample the DUT over several cycles of the sine stimulus.  
With a coherent clocking system, you know both the analog  
stimulus and the sampling clock frequencies, thus eliminating the  
need for antialias filters or time-domain window functions. In a  
coherent sampling system, all the power from the signal and its  
accompanying harmonics fall into predictable frequency bins.

12-bit resolution, excellent frequency resolution, and passband  
flatness. Stimulus-response instruments such as network analyzers  
and ATE test systems will benefit from using the PXI-5404 as the  
sine stimulus because of its passband flatness, and its frequency  
accuracy and resolution.  
The PXI-5404 can also serve as a programmable clock generator  
for ATE systems because of its 1.07 µHz frequency resolution, duty-  
cycle adjustability from 25 to 75 percent, and programmable voltage  
levels of 5, 3.3, or 1.8 V into high-impedance loads.
