National Instruments PXI-5651 PXI RF Analog Signal Generator

The NI PXI-5651 (Part Number: 779670-01, 191967M-02L) is a 3.3 GHz Analog Signal Generator that can coordinate the signal generators, which follow the business standard plug-and-play resolutions for the PXI bus, with compatible frameworks. This DDS reference signal delivers the essential fine-tuning steps of the synthesizer; the incorporated RF recurrence steps are ordinarily 1 Hz or less. Following the fundamental synthesizer are dividers and multipliers to scale the frequency over the scope of 50 MHz to the upper frequency range of PXI-5651 signal generators.

The automatic leveling control (ALC) circle performs fine adequacy control. The ALC has a wide frequency reaction, regularly from a couple of kilohertz to greater than 3.3 GHz. A temperature-stable voltage digital-to-analog converter (DAC) sets the reference for the ALC. Extra temperature adjustment performed amid the assembling procedure makes the ALC extremely stable over the predetermined working temperature. Attenuators (last square of the framework) perform coarse amplitude control. These attenuators have a typical scope of 100 dB.

The NI-RFSG instrument driver included utilizes adjustment information stored in the EEPROM to effectively set up the equipment for signal generation. The instrument driver utilizes alignment information to compensate for nonideal components and temperature variety.

This model offers -110 dBc/Hz phase noise at 1 GHz, 10 kHz typical offset, FM, 2-FSK, OOK regulation, modulating waveforms incorporate sine, triangle, square, 31-arrange PRBS, and client characterized 1020-piece. The NI PXI-5651 Signal Generator can use a tunable nearby oscillator or clock source and a NI PXI-5660 RF vector signal analyzer for jolt stimulus response or tracking generator applications.
