Ultra-fast sampling board runs up to 125Mbit/s
The UF.7021 is a full-length PCI board with 64 digital input or output channels that can simultaneously capture and replay signals at a maximum sample rate of 125Mbit/s.
64Mbyte signal memory is standard but this can be expanded to 4Gbyte, allowing long recordings at the high sample rates.
The cards are supplied with drivers for Microsoft Windows and Linux, with free downloads of future OS version drivers such as Windows Vista.
Drivers for Matlab, LabView, VEE, DasyLab and LabWindows/CVI are available as cost options.

Ultra-fast performance from arbitrary board
The UF6000 is a high-speed arbitrary waveform generator board from Strategic Test.
Each input channel has its own ADC and amplifier.
This ensures true simultaneous recording on all channels and allows the user to program the input voltage range and DC voltage offset to best match each sensor.
Up to 16 cards can be configured as a synchronous system of up to 128 channels, sharing a common internal or external clock.
It is possible to set trigger conditions on multiple cards combined with and/or, a feature often used in production test processes.
Apart from the external trigger that is standard on all UF2 cards, each channel can be programmed with edge, window, slope and pulsewidth triggers.
A re-arm trigger condition has been introduced on the UF2 series that reduces the possibility of false triggering on noisy signals.
Whereas many digitiser cards have fixed sample rate ranges, the UltraFast cards have always allowed the user to use a fine resolution sampling rate.
The resolution depends on the chosen sample rate (an application note is available on request).
The user simply programs the sampling rate required and the driver adjusts the onboard PLL and hardware driver to deliver the closest clock possible.
The new UF2 series employs a new design that has even finer resolution and also offers the possibility to install a user specific quartz when an exact sampling rate is required by the application - a feature claimed to be unique.
A number of application specific cost-options are available.
Multiple recording uses a memory segmentation technique to allow recording of a high-speed series of, such as radar signals.
Gated sampling only records when the external gate TTL signal supplied by external equipment goes high or low (user definable).
The ABA mode was known on traditional transient recorders, but until now has not been available on PCI cards.
Introduced in the UF2 series, it allows a slow and fast sampling rate to be defined so that memory is conserved prior to the trigger event and the critical signal recorded at the faster required sampling rate.
Engineers who need to record high-speed digital signals for synchronisation with the analogue, can use the fast digital inputs option that adds four TTL input lines to each A/D channel, and records them at the same sample rate.
The BaseIO option is most often used to control external equipment or to read/write status signals.
It adds eight TTL lines programmable directionally in two 4bit groups.
Finally, the timestamp option is used to record the time that each trigger occurs, but can also be fed with a GPS time signal to synchronise multiple cards operated at different locations.
The Ultrafast UF2-3130 cards are available immediately and have the following price ranges: the two-channel version costs Eur 3260; the four-channel version is Eur 4280 and the eight-channel model is priced at Eur 7250.
Volume discounts and OEM customisation prices are available on request.
