National Instruments 778692-03

The National Instruments part number 778692-03 is a high-performance Arbitrary Waveform Generator, specifically the PCI-5421 model, equipped with 256 MB of onboard memory. This generator is notable for its versatility, allowing users to tailor settings to suit their testing requirements. It supports two distinct output modes: arbitrary sequence mode and arbitrary waveform mode, enabling selection of waveforms from its onboard memory or through segmented sequences. With a vertical resolution of 16 bits, the PCI-5421 ensures accurate and precise signal generation while each of the output channels features 512 kS of waveform memory. The maximum sample rate for the sample clock is 100 MS/s, supporting a variety of waveform shapes with different maximum frequencies. Utilizing a high-gain amplifier allows for a maximum frequency of 43 MHz for sine waves, whereas square waves, ramp waves, and triangle waves can achieve maximum frequencies of 12.5 MHz, 5 MHz, and 5 MHz, respectively, when specific filters are disabled. In contrast, using a low-gain amplifier increases the maximum frequency for square waves to 25 MHz. To ensure safety and compliance, the 778692-03 adheres to various electromagnetic compatibility (EMC) standards, including EN 61326-1, EN 55011, AS/NZS CISPR 11, FCC 47 CFR, and ICES-001. This device is backed by a three-year warranty from National Instruments.
