Strategic Test Corp. has developed two 8bit digitizer/oscilloscope PCIe cards. The UF2e-2020 has two 50MSps channels, while the UF2e-2021 has four 50MSps. Each channel has its own 8bit ADC for simultaneous sampling, seven programmable input voltage ranges from ?50mV to ?5V, offset adjustment to 400 percent and both 50 and 1M input impedances. Unique features of the UF2e-2020 and UF2e-2021 include the option for dual-timebase sampling, synchronous digital inputs, asynchronous digital I/O and the ability to synchronize up to 542 channels.

With up to 4GSamples of on-board memory, the cards are able to record signals for 40s on two channels and 20s on four channels. Alternatively, captured data can be streamed continuously to PC RAM or hard disk(s) at up to 120MSps over the PCIe bus.

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 5.3 oscilloscope program. SDK's for Matlab, LabVIEW, Agilent-VEE, DASYLab and LabWindows/CVI are available as options.

Key specifications of the UF2e-2020 include 64MSamples memory (expandable to 4GSamples), continuous streaming to host PC >120MSps, effective number of bits >7.6LSB, SNR >47.5dB and total harmonic distortion The standard -3dB bandwidth is >25MHz, the Wide Bandwidth option increases this to >40MHz.

Like all UltraFast boards, the UF2e-202x scope cards can be customized through hardware options to best match the application:

? Onboard memory: 64-, 128-, 256-, 512-, 1,024-, 2,048- or 4,096MSamples

? Multiple Recording: memory segmentation

? Gated sampling: output clock controlled by external TTL signal

? TimeBase: records time of trigger events or Gates

? ABA Mode: slow-fast-slow recording on trigger

? Star Hub: synchronization of up to 5 or 16 boards, or 5 to 16 PC's to a maximum or 271 boards. Can be used with Digitizer, AWG and Digital I/O boards to create mixed-mode systems

? Digital inputs: adds 8 synchronous digital inputs

? BaseXIO: adds 8 asynchronous digital I/O lines.

Prices start at $3190 with volume/OEM discounts available.
