Strategic Test Corp. (Woburn, MA) offers two new 250 kHz 16-bit data acquisition cards for PCI Express. The UF2e-4721 has 16 analog inputs and the UF2e-4020 has 8 channels. Features include the options for dual- timebase sampling, synchronous digital inputs, asynchronous digital I/O, and the possibility to synchronize up to 4336 channels. Drivers and programming examples for Microsoft Windows Vista, XP64, XP, and Linux are supplied with the card, as well as the SBench 5.3 oscilloscope program. SDKs for MATLAB, LabVIEW, Agilent-VEE, DASYLab, and LabWindows/CVI are available as options.
The UF2e-472x scope cards have a signal-to-noise ratio of over 90.6 dB, total harmonic distortion of less than -105.0 dB, and the standard -3dB bandwidth is over 125 kHz. The cards have a 32 megasample memory that is expandable to 2 gigasamples. Each channel has its own 250 kHz ADC for true simultaneous sampling, together with eight voltage ranges from ±50 mV to ±10V, a programmable offset of 100%, and input impedances of 50 Ohm or 1 MOhm, allowing each channel to be individually configured for the signal source. The scope cards can be customized with hardware options to best match the application.
