National Instruments 779177-02 Arbitrary Waveform Generator

Part Number 779177-02 is the identifying part number for the National Instruments PCI-5412 Arbitrary Waveform Generator. The 779177-02 features an analog output channel CH 0 that can output full-scale voltages from 12.00 Vpk-pk to 5.64 mVpk-pk into a 50 Ω load. The resolution of the DAC is 14 bits and a SMB jack is used as the connector. Likewise, it has a bandwidth of 20 MHz and offers DC coupling. 

The 779177-02 offers multiple options on sample clock sources. First, there are the internal, divide-by-N (N >=1) and the internal, DDS-based, high-resolution clocks. Likewise, external sources can be connected through the CLK IN with the help of an SMB front panel connector. The Divide-by-N clock has a sample rate range of 23.84 S/s to 100 MS/s whereas the high-resolution clock has a sample rate range of 10 S/s to 100 MS/s. Furthermore, the CLK IN can offer a sample rate range of 200 kS/S to 105 MS/s.

The 779177-02 measures 13.4 × 0.8 × 4.2 in. in physical dimensions and weighs 480 g. The device uses the Synchronization and Memory Core (SMC) technology that allows waveforms and instructions to share the onboard memory. The standard onboard memory size for this part number is 32 MB. The 779177-02 offers two output modes: the arbitrary waveform mode where a single waveform is selected from a set of waveforms and the arbitrary sequence mode, where a sequence directs the device to produce a set of waveforms in a specific manner. The device can consume 22 W of power during normal operation and 26 W during overload operation. 

The 779177-02 is recommended for operation between temperatures of 0 °C to 55 °C (0 ºC to +45 ºC when installed in an NI PXI-101x or NI PXI-1000B chassis), with a relative humidity of 10% to 90%. On the other hand, it can be stored between a wider temperature range of –25 °C to 85 °C at a relative humidity of 5% to 95%. The device is intended for indoor use only and within a maximum altitude of 2000 m.
