Overview
The National Instruments PXI-5404 is a 100 MHz frequency
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.
The PXI-5404 is a versatile, cost-effective, sine wave generator
with output levels ranging from 1 to 2

into a 50
Ω
load with
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.

Ideal for Coherent
Clocking Applications
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
you have a precise phase and
frequency relationship between the

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.

application is the testing

converters (ADCs). Here
the sine stimulus is fed to
the ADC and the clock
