National Instruments 782248-01

The National Instruments 782248-01 is an AT-1120 Signal Generator Adapter Module designed for use with FlexRIO. This module features a single analog output channel, offering a 14-bit DAC resolution and a sampling rate of 2 GS/s. The DC-coupled analog output can be configured as either single-ended or differential, accommodating load impedances of 50 Ω or 100 Ω. When operating with a 50 Ω load, the full-scale amplitude for a 1 kHz sine wave is 1 Vp-p in single-ended mode and 2 Vp-p in differential mode. The output common mode voltage ranges from -0.9 V to 0.9 V open and -0.45 V to 0.45 V at a 50 Ω load. With an impressive rise/fall time of 340 ps (10% to 90%), a bandwidth of 1 GHz, and an overshoot of less than 5% for a 0.5 Vp-p pulse, this module excels in high-performance applications. The clock pattern random jitter is typically below 5 ps. The analog output utilizes an SMA connector with an output impedance of 50 Ω (single-ended) or 100 Ω (differential), supporting a maximum output current of 22 mA at a 50 Ω load. It also includes an external clock input channel with SMA connector, accepting input voltages from -10 dBm to 8 dBm at an impedance of 50 Ω, with an operational frequency of 2 GHz (±0.1%). Furthermore, the module offers an external trigger input and output, both using the SMA connector, with the trigger input supporting data rates up to 140 Mbps. The output trigger level is 3.3 V open (1.65 V with 50 Ω load) with an impedance of 50 Ω. Note that this module is exclusively compatible with a FlexRIO FPGA module, ensuring seamless integration within your system.
