Advantech PCI bus data acquisition and control card | Analog Input Card PCI-9812 PCI-9812 Products with four 20MHz sampling frequency synchronized A / D converter. Speed ??and simple to use make PCI-9812/9810 is suitable for many applications, such as digital images, medical applications, vibration test equipment and RF or baseband signal is digitized. PCI-9812 provides the best cost-effective solution for high-end applications. Features 32-bit PCI bus, plug and play up to 20 MHz per channel sampling frequency synchronization four single-ended input channels 12 (9812) or 10 (9810) 4 analog input resolution A / D converter, for Each analog channel provides a converter board with a 32k-word FIFO bipolar analog input range (+/- 5V, + / - 1V) five kinds of A / D trigger mode: software trigger, pre-trigger, after trigger, trigger and delay trigger bus master DMA data transfer sampling frequency programmable compact, half-length card structure Specifications analog input (A / D) maximum sampling frequency: 20 MHz Note: When using only one channel The maximum sampling frequency of 20 MHz. When using two channels, only the number of samples in each channel is lower than 16K can be achieved when the sampling frequency of 20MHz. When using four channels, each channel only when the number of samples is less than 8K sampling frequency of 20MHz can be achieved. Converter: BB ADS800 series or other equivalent converter input channels: four single-ended input channels Resolution: PCI-9812: 12 位 PCI-9810: 10-bit input range: Bipolar: + 1V or + 5V ( Input impedance gain error + 1.5%:: 50 / 1.25K / 15M Ω (card spot by choice) FIFO size: card spot by choice) the overall accuracy of 32K words, each channel 8K words trigger source: software trigger, external digital trigger and external analog trigger (via trigger level and the internal D / A set compared) Trigger: software trigger, pre-trigger, post-trigger, trigger and delay trigger data transmission: only bus master DMA mode clock source: internal clock, external digital clock, external sine wave. (Note: The external clock frequency is twice the frequency of the AD converter.) Internal clock frequency: Programmable select 40MHz / n (n = 2,4,6,8 .. * 256) Digital input: Number of channels: 3-way TTL (. 10K Ohm pull-down resistor) compatible Input level: Low: The lowest 0V; maximum 0.8V High: Minimum + 2.0V input load: Low: + 0.5V @ 0.2mA maximum height: max + 2.7V @ 20mA general characteristics: Connectors: 5 BNC connectors for analog input (channel # 0 to # 3, the external clock) a 9-pin connector for digital inputs and trigger input (with accessory after the panel joints lead to the chassis panel. ) Operating temperature: 0 ° ~ 50 ° C Storage Temperature: -20 ° ~ 80 ° C Humidity: 5 to 85%, non-condensing power consumption: typ +5 V @ 1.4A Dimensions: 173 mm x 108 mm fttilslli
