This single-channel generator features a BNC output connector and utilizes advanced direct digital synthesis (DDS) technology, enabling it to accurately produce a wide range of signals including pseudorandom noise, direct current (DC), as well as standard waveforms such as sine, square, triangle, and ramp shapes. The output voltage spans from -5 V to +5 V (AC peak + DC), with an impressive DAC resolution of 14 bits, making it suitable for diverse applications in automation and control. \u003c\/p\u003e\n\n\u003cp\u003eFor a 50 Ω load, the amplitude range is 5.64 mV peak-to-peak to 10 V peak-to-peak; for high-impedance applications, it extends from 11.28 mV peak-to-peak to 20 V peak-to-peak, thereby offering flexibility depending on the load characteristics. With a guaranteed AC amplitude accuracy of ±2.0% of amplitude + 1 mV and a DC offset accuracy of ±0.5% of offset ±2 mV, the PXI-5402 ensures reliable and precise signal generation. Additional features include signal summing capabilities, customizable output impedance (50 Ω or 75 Ω), and various triggering modes including Single, Continuous, Stepped, and Burst.\u003c\/p\u003e\n\n\u003cp\u003eThe device incorporates a Phase-Locked Loop (PLL) Reference Clock with multiple source options such as REF IN and PXI_CLK10, facilitating accurate timing and synchronization across systems. Frequency accuracy is achieved with a lock time of 70 ms (normal) to 200 ms (maximum), depending on the selected PLL reference. Options for edge detection and a minimum pulse width of 25 ns further enhance its functionality. For ongoing precision, the PXI-5402 supports external and self-calibration processes, with self-calibration completed in approximately 105 seconds utilizing an integrated 24-bit ADC and precision voltage reference. Calibration constants are stored in nonvolatile memory, ensuring reliability and adherence to specifications, with recommendations for recalibration at intervals not exceeding two years.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683812626668,"sku":"779655-01","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/National_Instruments_Group_Photo_-_Final_Compressed_a109e420-a21c-459d-8c87-fe4e75889a06.jpg?v=1753243023","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-779655-01","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
