National Instruments 781261-01 RF Vector Signal Generator

National Instruments 781261-01 (an identifying part number for the PXIe-5673E Model) RF Vector Signal Generator is a comprehensive solution designed for RF signal generation and modulation tasks in various industrial and research settings. It is made up of multiple PXI Express hardware modules, such as the PXIe-5611 IQ modulator, the PXIe-5450/5451 arbitrary waveform generator (AWG), and the PXIe-5650/5651/5652 RF analog signal generator (LO source). When combined, these modules provide an impressive instantaneous bandwidth of 100 MHz and a broad frequency range of 85 MHz to 6.6 GHz.

With an amazing dynamic range of 156 dB compression-to-noise, the 781261-01 is an excellent signal deliverer. At 0 dBm output level, its noise density is usually as low as -144 dBm/Hz. Complex signal creation processes are made easier for users by the efficient storing and manipulation of signals made possible by the onboard waveform memory.

A notable characteristic of this system is the smooth integration made possible by the NI-RFSG instrument driver software, which enables every module to operate as a single, cohesive unit. This smooth functioning increases overall efficiency by streamlining configuration and control.

The system is physically contained within a PXI/3U CompactPCI form factor that has four slots wide, guaranteeing compatibility and simple integration with current configurations. Each module's front panel connectors, which include SMA and SMB connectors for a range of input and output signal types, provide flexible connectivity choices.

The 781261-01 has fast rise and fall periods (less than 5 ns) and a maximum pulse repetition frequency (50 MHz) for pulse modulation. Furthermore, it offers accurate control over output parameters and strong overload prevention features.

To provide dependable and secure operation, the PXIe-5611 IQ modulator module has overload protection for both DC input and RF power. With exact power output resolution and impedance matching, the front panel's LO output operates across a broad frequency range of 50 MHz to 6.6 GHz.

The National Instruments 781261-01 RF Vector Signal Generator is an indispensable instrument for wireless communications, radar, electronic warfare, and RF component testing.
