Strategic Test introduced the UF3-3242 and UF3-3240 12-bit digitizer cards for the PCI bus. The UF3-3242 has 2 analog inputs and can sample at 500 MS/s on one channel or 250 MS/s on both channels simultaneously. The UF3-3240 is a single-channel card that samples at up to 500 MS/s. Both cards are supplied with 128 MSamples (256 MByte) onboard memory. The memory can be expanded to 2 GSamples giving a measurement time of up to 5 seconds on one channel at 500 MS/s. The single-channel UF3-3242 card is priced at $7895 and the two-channel UF3-3240 is $8695, with volume/OEM discounts available. PCI Express versions of the cards will be released later this year.
UF3-324x Scope Card Hardware Options
- Onboard memory: 128, 256, 512, 1024 or 2048 mega samples
- Multiple Recording: memory segmentation
- TimeBase: records time of trigger events
- Star Hub: synchronization of up to 8 boards. Can be used with Digitizer, AWG and Digital I/O boards to create mixed-mode systems
- BaseXIO: adds 8 asynchronous digital I/O lines
Drivers and programming examples for Microsoft Windows 7, 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.
Measured dynamic specifications at 500 MS/s are a Signal-to-Noise Ratio (SNR) of up to 63.1 dB and an effective Number of Bits (ENOB) value of 10.2 LSB. At 250 MS/s the SNR is up to 63.8 dB and an ENOB of 10.3 LSB.
The UF3 Series features 5 multi-purpose connectors routed to the clock input, trigger input, trigger output and 2 freely programmable I/O connections. 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 6 input ranges from ±200 mV to ±10 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 allows AC or DC coupling, and includes a user-activated low-pass filter.
