 Strategic Test's digital pattern generator boards

Strategic Test has released four new digital pattern generator boards for PCs featuring up to 32Gbit memory, maximum clock rate of, 10MHz or 5MHz and a choice of 16bit or 32bit widths.

Each 4bit (nibble) can be programmed with a different high and low output level from -2V to 10V in 10mV increments. This output range can generate signals compatible with ECL, PECL, TTL, LVDS, LVTTL, CMOS and LVCMOS. The company said that the UF2-7200 series is low-cost, easy-to-use and eliminates the need for multiple instruments to produce different signal levels.

The signal data can be generated from card memory, continuously looping until stopped by the user or streamed continuously from the host PC at rates up to 225MBps when very long signals are required.

The output rate of the signals can be programmed from DC to 40MHz. Each channel can drive a maximum current of 100mA (maximum 200mA per nibble). Differential signals such as ECL and LVDS are generated in the on-board hardware. This has the advantage that only one data-bit is used for each pair of differential signals so that less on-board memory is used.

Software drivers for Windows Vista, XP64, XP, 2000, NT, ME, 98 and Linux are supplied, while drivers for MATLAB, LabVIEW, VEE and DASYLab are available as options.

The model UF2-7210 (10MHz on 16bits, 512Mbit memory) sells at $3,490 each while the UF2-7211 (10MHz on 16bits or 5MHz on 32bits, 512Mbit memory) starts to sell at $4,290. The two other parts UF2-7220 (40MHz on 16bits, 512Mbit memory) and the UF2-7221 (40MHz on 32bits, 512Mbit memory) are priced at $4,390 and $5,590, respectively.

All UltraFast cards are supplied with free drivers for Windows and Linux, the SBench measurement and signal generation program, source code programming examples in Visual Basic, C/C++ and D.
