National Instruments 781216-01 PXI RF Analog Signal Generator

The part number 781216-01 from National Instruments is the identifying part number for the PXIe-5651 PXI RF Analog Signal Generator. This module has a frequency range from 500 kHz to 3.3 GHz, making it suitable for communications system testing, and general-purpose RF testing.

The 781216-01 PXI RF Analog Signal Generator has a broad frequency range from 500 kHz to 3.3 GHz. It has fine frequency resolution, with steps as small as less than 3 Hz for frequencies up to 1.3 GHz and more than 6 Hz for frequencies from 1.3 GHz to 3.3 GHz. The internal reference clock makes this RF generator more accurate, with an initial accuracy of ± 3 parts per million and a maximum aging rate of ± 5 parts per million per year. The module has single sideband phase noise as low as -111 dBc/Hz at a 10 kHz offset for a 100 MHz carrier ensuring high signal fidelity. The 71216-01 PXI RF Analog Signal Generator exhibits low residual FM and jitter, allowing it to enhance its performance in generating clean and stable RF signals.

The generator device can perform amplitude control with a resolution of less than 0.1 dB. The amplitude range in this device varies with frequency, allowing outputs from -90 dBm to 10 dBm depending on the frequency band. The module features power level accuracy within ± 0.75 dB for output powers greater than -40 dBm and within ± 1.8 dB for lower output powers, making the amplitude control more reliable.

This part supports various modulation types, including frequency modulation, frequency shift keying, and on-off keying. The device can generate FM with maximum deviations ranging from 125 kHz to 4 MHz, depending on the frequency band. FSK modulation supports deviations from 31.25 kHz to 1 MHz, and OOK modulation operates over a similar range, making the 71216-01 PXI RF Analog Signal Generator a versatile tool for generating complex RF signals. This module has a temperature range between 0 degrees Celsius and 55 Degrees Celsius and does not feature an Ingress protection rating.
