Overview
NI 5406 and NI 5402 devices are 100 MS/s, 40 and 20 MHz arbitrary
function generators (AFGs) that feature up to 16 bits of resolution and
32 kB of onboard memory for arbitrary function generation in a compact,
1-slot 3U PXI module or PCI board. Using these devices, you can combine
the power of a stand-alone function generator with the flexibility and
benefits of your computer to create highly capable virtual instrumentation
solutions. Direct digital synthesis (DDS) is used to precisely generate
waveforms that are repetitive in nature, including sine, square, triangle,
ramp, noise, and DC waveforms.
Frequency Hops and Sweeps
The function generator uses DDS, which is a technique for deriving, under
digital control, an analog frequency source from a single reference clock
frequency. This technique is used to achieve high-frequency accuracy and
resolution; temperature stability; and rapid, phase-continuous frequency
switching. All frequency sweeping and hopping is phase-continuous,
and you can generate a burst of several tones. Frequency sweeping and
hopping is implemented through a frequency list of steps, each of which
defines frequency and duration. Complex frequency lists can be
instructed with 32 MS/s of available instruction memory.
Analog Output Performance
These devices feature unparalleled analog output performance in PXI
and PCI. The analog output path features a 7-pole elliptical analog filter
to suppress high-frequency signal images. Depending on your signal and
application needs, you can select up to a 4X digital interpolation for an
effective sampling rate up to 400 MS/s. Additionally, the analog output has
a passband flatness of ±0.4 dB across the bandwidth for sine generation.
Timing and Synchronization
Using NI-TClk synchronization technology, you can synchronize multiple
NI signal generators for applications requiring a greater number of
channels. Because it is built into the Synchronization and Memory Core
(SMC), NI-TClk can synchronize NI signal generators with SMC-based
high-speed digitizers and digital waveform generator/analyzers for
tight correlation of analog and digital stimulus and response. Using
onboard calibration measurements and compensation, NI-TClk can
