PCI cards

Strategic Test Corp has announced two 400 MS/s 14-bit digitiser cards for the PCI bus.

The UF3-4142 has two 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 MB) onboard memory. The memory can be expanded to 2 GSamples giving a measurement time of up to 5 s on one channel at 400 MS/s.

The cards are the first in the UF3 series, which is based on a 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.

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 six input ranges from ±100 mV to ±5 V and a choice of 50 Ω or 1 MΩ input impedances.

The second path delivers a bandwidth of \>200 MHz, has four input ranges from ±500 mV to ±5 V and has 50 Ω impedance. The new front-end module now allows AC or DC coupling and includes a user-activated low pass filter.
