Strategic Test has announced two 400 MS/s 14-bit digitizer cards for the PCI bus. The UF3-4142 has 2 analog inputs and can sample at 400 MS/s on one channel or 250 MS/s on both channels simultaneously, while the UF2-4140 is a single-channel card that samples up to 400 MS/s. Both cards are supplied with 128 MSamples (256 MByte) onboard memory which is unique at this speed/resolution segment. The memory can be expanded to 2 GSamples giving a measurement time of up to 5 seconds on one channel at 400 MS/s. PCI Express versions of the cards are due to be released in June.

These cards are the first in the new UF3 Series, which is based on a totally new baseboard design. A unique feature on the two digital I/O lines allows them to be programmed as digital inputs that are synchronous with the analog channels or as synchronous digital I/O lines used to control external equipment or receive status signals, or as additional trigger inputs that can be AND/OR with the main external trigger input.

“The new UF3 Series gives our customers a combination of speed, resolution and memory depth that can’t be found in other manufacturer’s products”, commented Bob Giblett, president of Strategic Test. “With prices $1000 to $3000 less than our major competitors, the UF3-4140/1 offer an outstanding value”.

Each channel includes its own ADC for simultaneous sampling without phase errors. There are two user-selectable input paths per channel on the card. The first path has 6 input ranges from ±100 mV to ±5 V and a choice of 50 Ohm or 1 MOhm input impedances. The second path delivers a bandwidth of >200 MHz, has 4 input ranges from ±500 mV to ±5 V and has 50 Ohm impedance. The new front-end module now allows AC or DC coupling, and includes a user activated low pass filter.

Drivers and programming examples for Microsoft Windows Vista, XP64, XP and Linux (RedHat, Fedora, SuSe, Sarge) are supplied with the card, as well as the SBench 6.0 oscilloscope program. SDK’s for MATLAB, LabVIEW and LabWindows/CVI are available as options.
