Keywords:oscilloscope; digital I/O; 4 GigaSamples 

Strategic Test Corp. has announced two new 8-bit digitiser / oscilloscope PCI Express cards. The UF2e-2020 has two 50MS/s channels, while the UF2e-2021 has four 50MS/s. Each channel has its own 8-bit ADC for simultaneous sampling, seven programmable input voltage ranges from ±50 mV to ±5 V, offset adjustment to 400 per cent and both 50 Ohm and 1 MOhm input impedances. Unique features of the UF2e-2020 and UF2e-2021 include the option for dual-time base sampling, synchronous digital inputs, asynchronous digital I/O and the ability to synchronise up to 542 channels.

With up to 4 GigaSamples of on-board memory, the cards are able to record signals for 40 seconds on 2 channels and 20 seconds on four channels. Alternatively, captured data can be streamed continuously to PC RAM or hard disk(s) at up to 120 MSamples/s 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 64 MSamples memory expandable to 4 GSamples, continuous streaming to host PC > 120 MSamples/s., effective number of bits > 7.6 LSB, signal-to-noise ratio > 47.5 dB, total harmonic distortion < -56.0 dB.

The standard -3dB bandwidth is > 25 MHz, the Wide Bandwidth option increases this to > 40 MHz.

Like all UltraFast boards, the UF2e-202x scope cards can be customised through hardware options to best match the application:Onboard memory: 64, 128, 256, 512, 1024, 2048 or 4096 MegaSamples, 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: synchronisation of up to 5 or 16 boards, or 5 to 16 PC's to a maximum or 271 boards. Can be used with Digitiser, AWG and Digital I/O boards to create mixed-mode systems, digital inputs : adds 8 synchronous digital inputs and baseXIO : adds 8 asynchronous digital I/O lines

Prices start at Rs.1.29 lakh ($3190) with volume/OEM discounts available.
