Now supplied in Australia by Westek Electronics , Teseq DDS-3005 USB CI 250 arbitrary waveform and ring wave generators have been engineered as simple function generators that can be used with the NSG 5600 or to directly control a power amplifier or battery simulator.
The ring wave arbitrary function can be programmed on these waveform generators, making them suitable for the Ford standard EMC-CS-2009 CI 250.
While performing test runs, a PC transfers waveform data to the memory of the ring wave generators via the USB bus. The period waveform data is then sent to the relevant DAC circuits, with the DDS (Direct Digital Synthesized) circuit producing the corresponding DAC refreshing clock.
The single channel memory has a capacity of 256 kilosamples of 14 bits vertical resolution, and the DAC clock is programmable in 0.2 Hz steps from 0 to 50 MHz.
