Description

Features

• 4-lane PCI Express board
• Extended operating temperature range: -20 °C to +85 °C

Analog inputs

• 4 SE or diff. (+/-) inputs (via SMB connector)
• 1 A/D converter per channel: Simultaneous acquisition at all analog inputs
• Sampling frequency: 125 kHz, 250 kHz, 500 kHz, 1 MHz, 2 MHz, 4 MHz
• 24-bit resolution (sampling frequencies of 2 MHz and 4 MHz: 23-bit resolution)
• Input range: ± 10 V, ± 1 V
• Coupling: AC, DC, GND (programmable for each channel)
• Overvoltage protection
• Optical isolation between analog channels and from the PC (1000 V)
• Anti-aliasing filters as integrated digital filters, cut-off frequency changes according to sampling frequency, automatic adjustment to Nyquist frequency
• Analog filters with fixed cut-off frequency (3 MHz)
• 1 current source per channel for IEPE sensor supply (4 mA to 26 V)
• 24 V trigger input (via SMB connector)

Digital I/O

• 4 digital inputs, 24 V, optically isolated
• 4 dig. outputs, 24 V, optically isolated

Input modes

• Simple mode: Reads single analog value
• Cyclic mode (auto stop): Starts analog acquisition through software, stops acquisition when configured number of values has been reached, analog values are available in software buffer
• Cyclic mode (ring buffer): Starts analog acquisition through software, continuous acquisition until software stop, analog values are available in software buffer
• Gate logic: Each digital input controls the acquisition of the corresponding analog input (digital input 0 -> analog input 0, digital input 1 -> analog input 1, etc.) via rising edges (from 0 to 1: acquisition is started) and falling edges (from 1 to 0: acquisition is stopped). The data of the respective analog input is stored in a temporary buffer on the board before it is transferred to the PC.
