Overview
The UF2-7200 series of high-speed Digital Pattern Generator cards are used to generate digital signals with clock rates of up to 40 MHz. Applications include testing electronic components (e.g. ADC's, DAC's, FPGA's) and electronic systems. Compared to traditional pattern generators, these cards are less expensive, have memory depths of up to 4GigaBytes. At slower clock rates the cards can output very long signals using the streaming mode directly from the PC's hard disks. The Strategic Test cards are designed to offer maximum versatility, ease of programming, long-term reliability and low power consumption. Manufactured in Germany the instrument cards include a two year hardware warranty combined with lifetime technical support and software updates - which includes new drivers for future operating systems and third-party software.
Digital Outputs
The UF2-7221 Digital Pattern Generator card card allows you to generate digital signals with clock rates from 1 kHz to 40 MHz on 32 bits, 16, 8 or 1 to 4 bits. When using 16 or less bits all of the card memory can be used allowing longer replay times – a feature that's unique to the ST cards. The outputs are programmable from -2.0V to +10.0V and every 4 bit groups HIGH and LOW levels can be programmed with different levels which means you don't have to use different devices to support multiple logic families. Logic families supported include: ECL, PECL, TTL, LVDS, LVTTL, CMOS and LVCMOS. If differential signals are required, these are generated in hardware so that only one data bit is used for each differential pair which saves memory space. Capable of driving 110 Ohm termination.
Deep Signal Memory and Streaming to the PC
The Pattern Generator card comes with 256 MBytes signal memory that can be expanded at the factory in increments up to 4 GBytes. Like all of the Strategic Test cards there are two operating modes. In Standard mode the data to be generated is first stored to the on-board memory. Output is started on software or external TTL trigger and the signal(s) are output once, n times, or repeated until the card is stopped by software. This mode allows the cards to output at the maximum clock rate. While generating, the card operates independently of the host PC so the cpu can be used for other tasks.
Alternatively, the FIFO mode allows data to be continuously transferred from the PC to the UF2 card during the output, so that much longer signals than the on-board memory can be generated. However, the PCI-X bus has a maximum continuous transfer rate (not to be confused with Burst Transfer which is higher) of approximately 225 MBytes/s - so this can limit the maximum output rate during streaming.
Sampling Clock
Unlike other instrument cards that offer a limited choice of fixed output rates, the UF2 cards allow you to set an output rate with a fine degree of accuracy by using one of the six different modes available that use a combination of internal 10 MHz reference clock, PLL, hardware divider, quartz clock, external reference clock and external clock. There is also a factory option to install a second quartz for applications that require highest accuracy and stability at a customer-specific output rate. The external clock connector can be programmed as either an input or as an output when you want to synchronize external equipment.
Flexible Triggering
In addition to the standard external TTL trigger, the XBaseIO option can be used to AND/OR two more external trigger inputs.
The External Trigger connector can be set to either input or output when you need to synchronize the start of measurement with external equipment.
Synchronization
The Star Hub option is available in two versions that synchronize the clock and trigger signals of either up to 5 cards or 16 cards within the PC. All analog outputs will be perfectly synchronized with no phase error between channels. It's also possible to configure mixed mode systems that contain a mixture of digitizer, arbitrary waveform generator and high-speed digital I/O instrument cards.
This option only needs to be purchased for one card in the system and consists of a small daughterboard that is factory-installed to the card. The clock and trigger signals are then distributed by small ribbon cables to this and the other cards. The 16 card version being larger in size does require an additional PCI slot width.
For larger configurations, the System Star Hub option allows up to 271 cards to be synchronized by distributing the clock and trigger signals across up to 17 PC's.
