Acqiris Offers The World's First 10-Bit 4 GS/s, 3U PXI Digitizers For Fast RF And ATE Applications

Monroe, NY, November 2005 - Acqiris, a leading manufacturer of data conversion instruments, has introduced the world's first 10-bit, 4 GS/s, 3U PXI digitizers, with input bandwidths of up to 3 GHz. The dual-channel DC152 and single-channel DC122 digitizers significantly increase data acquisition and testing rates, making the new digitizers ideal for high-speed applications such as telecommunications and semiconductor testing, where test time should be limited only by the speed limits of the device under test (DUT). In addition, the input bandwidth of up to 3 GHz makes these high-precision, high-speed digitizers ideal for use in synthetic instrumentation systems for the replacement of standard digital multimeters, oscilloscopes, power meters, and frequency counters in RF and microwave test systems.

The DC152 and DC122 digitizers are fully compliant with both the PXI and CompactPCI standards, and are supported with AcqirisLive and AcqirisMAQS software and Windows, Linux, and VxWorks drivers for easy integration into production test and automatic test equipment (ATE). The single-slot, 3U PXI/CompactPCI digitizers incorporate Acqiris' proprietary XLFidelity and JetSpeed II ADC chipsets, introduced earlier this year.

The XLFidelity ADC front-end chipset integrates the signal conditioning, amplification and interleaving functions essential to high-speed data acquisition into two companion ASIC devices. The JetSpeed II chipset is designed to enhance high-speed ADC performance through the distribution of accurate timing signals, and synchronously pass the acquired data to onboard memory.

The DC152, with 2 GHz of bandwidth, provides synchronous sampling of 2 GS/s on both input channels with up to 256 Mpoints of optional acquisition memory; in single-channel applications this doubles to 4 GS/s and up to 512 Mpoints. The single-channel DC122 offers sampling rates of up to 4 GS/s with 512 kpoints of standard, or 512 Mpoints of optional acquisition memory. It also offers the choice of standard or high frequency front-ends that can be selected at the time of order, tailoring the digitizer module to the user's needs.

The 50 ohm input stage of the DC122 standard front-end is fully protected against overvoltage signals. The XLFidelity programmable front-end electronics are used to provide a complete set of input voltage ranges, from 50 mV to 5 V full scale (in a 1, 2, 5 sequence) with variable voltage offset. With a bandwidth of 2 GHz, the digitizers provide optimized amplifier response (flatness, overshoot and accuracy) to ensure the precision of high-frequency measurements. The front-end circuitry features switchable filtering, very fast recovery from out-of-range signals, and internal calibration, so there is no need to disconnect input signals.

The DC122 high-frequency input front-end gives direct access to the XLFidelity cross point switch in order to benefit from the full bandwidth of Atmel'sTS83102G0B ADC used in the digitizers. The full-scale range is fixed at 1 V, providing a bandwidth of 3 GHz. The input channel has an overvoltage protection to ±3 V.

Pricing for the new 3U PXI/CompactPCI DC152/DC122 10-bit digitizers begins at $16,480. Delivery is eight weeks ARO.
