Geotest Expands PXI Multi-Channel D/A Product Line
September 30, 2012. Geotest has announced the introduction the GX1649, a 64-channel, PXI arbitrary waveform generator with 16-bit amplitude resolution and an output voltage range of ±15 V. The GX1649 is organized into four groups of sixteen channels. For DC operation, each group can be programmed and triggered independently. All groups can be updated simultaneously, and each channel within a group can be programmed to a unique voltage.
When the instrument is used as a waveform generator, its 256-k sample memory is allocated to each group of sixteen channels, with the user being able to allocate the memory for one or all channels. With all 64 channels configured for AWG mode, the maximum sample rate is 625 kS/s. Each group can be clocked independently via a programmable clock source, or all groups can be clocked by a common source. Within any group, channels can be configured for a combination of AWG and DC operation.
The GX1649 also offers eight digital TTL I/O channels for general-purpose applications. These digital I/O channels also can be used as external clock inputs for each of the 4 channel groups.
“The GX1649 meets the needs for those customers who have high-channel-count applications for sensor simulation or for system test applications where a large number of DC/AC signal sources are required,” said David Manor, Geotest’s vice-president of engineering. “The GX1649 offers market-leading features and demonstrates Geotest’s on-going commitment and ability to deliver unique and differentiated PXI products for the test and measurement market.”
The GX1649 is a single-slot, 3U PXI module and is supplied with a full-featured API and user interface for a variety of software-development environments, including ATEasy, C, Visual BASIC, COM, and LabVIEW. Price is $2,995.
