The National Instruments part number 778692-02 is an advanced PCI-5421 Arbitrary Waveform Generator, featuring 32 MB of onboard memory equivalent to 33,554,432 bytes. Designed with sophisticated Synchronization and Memory Core technology, this device efficiently manages the usage of onboard memory, allowing for flexible settings regarding the maximum number of waveforms and the number of segments in a sequence list. The generator offers two output modes: arbitrary waveform and arbitrary sequence. In arbitrary waveform mode, users can select a single waveform from those stored in memory, while the arbitrary sequence mode allows for detailed instructions to output a series of waveforms in a specified order, facilitated by segments that define each waveform’s selection. The maximum memory capacity for arbitrary waveform mode is 4,194,176 samples, while the limit for arbitrary sequence mode is slightly lower at 4,194,120 samples. The robust design of the 778692-02 ensures reliable operation across a range of environments, with an operating temperature range from 0 ºC to +45 ºC (32 ºF to 113 ºF), and a storage temperature range from -25 ºC to +85 ºC (-13 ºF to 185 ºF). This device is suitable for use at altitudes up to 2,000 meters and complies with the IEC 60068-2-1 and IEC 60068-2-2 standards. The dimensions of the 778692-02 are 34.1 × 2.0 × 10.7 cm (13.4 × 0.8 × 4.2 in.), and it weighs 419 g (14.8 oz). The product comes with a comprehensive three-year warranty, ensuring quality and reliability for users in diverse applications.
