National Instruments PXI-5404 PXI Waveform Generator

The National Instruments PXI-5404 (Part Number: 778577-02) is a 100 MHz Waveform Generator packaged in a 1-slot PXI module. It produces sine and time outputs at up to 100 MHz with 1.07 µHz resolution. By utilizing direct digital synthesis (DDS) and precise phase-lock loop circuitry, the PXI-5404 produces steady, precise sine and clock outputs of which the user can automatically alter the amplitude, frequency, and phase of the sine and clock outputs and the duty cycle of the clock output. The PXI-5404 is an adaptable, practical, sine Waveform Generator with output levels running from 1 to 2 Vpp into a 50 Ω load with 12-bit resolution, astounding frequency resolution, and passband flatness.

Stimulus-response instruments, such as analyzers and ATE test frameworks will profit by utilizing the PXI-5404 as the sine stimulus due to its passband flatness, frequency accuracy, and resolution. The PXI-5404 can also serve as a programmable clock generator for ATE frameworks because of its 1.07 µHz frequency resolution, duty cycle customizability from 25 to 75 percent, and programmable voltage levels of 5, 3.3, or 1.8 V into high-impedance loads.

The NI PXI-5404 Waveform Generator is perfect for Coherent Clocking Applications. With the synchronous sine and clock outputs, it is possible to utilize intelligible timing to diminish the test time of the gadget under test and eliminate the requirement for anti-alias filtering. Since there is an exact phase and frequency connection between the analog stimulus and the sample clock, there is no requirement for window-weighting capacities in the FFTs for spectral examination, lessening the need to test the DUT more than a few cycles of the sine stimulus.
