National Instruments 778692-02 Arbitrary Waveform Generator Device
National Instruments part number 778692-02 is the version of the PCI-5421 Arbitrary Waveform Generator that has 32 MB of onboard memory, which is equal to 33,554,432 bytes. Waveforms and instructions may share the onboard memory of the 778692-02, thanks to its sophisticated Synchronization and Memory Core technology. This technology allows the user to change the memory use settings, which include the maximum number of waveforms that may be kept in memory and the number of segments that can be in a sequence list.
There are two different output modes available for the 778692-02: arbitrary waveform and arbitrary sequence. In the arbitrary waveform mode of the generator, a single waveform is selected from a group that is kept in the onboard memory. When the device is in arbitrary sequence mode, it receives instructions on what order to output a set of waveforms. These instructions are detailed on “segments”, which are individual parts of a sequence, and they determine which waveform is selected. The 778692-02's arbitrary waveform mode memory limit is 4,194,176 samples, while the memory limit of the arbitrary sequence mode is somewhat lower at 4,194,120 samples.
The robust design of the 778692-02 ensures continued operation in various environments. It has an operating temperature range of 0 ºC to +45 ºC (32 ºF to 113 ºF), and a much wider storage temperature range of –25 ºC to +85 ºC ( -13 ºF to 185 ºF). The waveform generator is able to be used effectively at altitudes up to 2,000 m, and it meets all of the specified standards of IEC 60068-2-1 and IEC-60068-2-2.
The 778692-02 measures 34.1 × 2.0 × 10.7 cm (13.4 × 0.8 × 4.2 in.), and weighs in at 419 g (14.8 oz).
