The National Instruments part number 782248-02 designates the AT-1120 Signal Generator Adapter Module for FlexRIO, designed to deliver high-performance signal generation capabilities. This module features two analog output channels, each equipped with a 14-bit digital-to-analog converter (DAC) that achieves a maximum sampling rate of 1.25 GS/s. The DC-coupled outputs can be configured as either single-ended or differential, providing versatility in signal distribution. The output impedance can be set to 50 Ω or 100 Ω. For a 50 Ω load with a 1 kHz sine wave, the full-scale output amplitude is 2 Vp-p (2.2 Vpp without calibration) in single-ended mode and 4 Vp-p (4.4 Vpp without calibration) in differential mode. The module supports a common mode voltage range from -1.6V to 1.6V in the open state, and -0.8V to 0.8V under a 50 Ω load. Additional performance specifications include a rise time and fall time of 500 ps and 550 ps respectively for a pulse at 0.5 Vp-p single-ended. The bandwidth is rated at 700 MHz, with overshoot less than 5% at 1 Vp-p and random jitter on clock patterns typically under 5 ps. The analog output is provided via an SMA connector, and the device requires a compatible FlexRIO FPGA module for operation. The external clock input channel, also utilizing an SMA connector, operates within a voltage range of -10 dBm to 8 dBm at an impedance of 50 Ω, with a frequency capability of up to 1.25 GHz. The external trigger input and output channels further enhance the module's capabilities, supporting data rates of 140 Mbps with precise output levels. The AT-1120 Signal Generator Adapter Module is an essential tool for high-fidelity signal generation in sophisticated industrial automation and control applications.
