National Instruments PXI-5650 PXI RF Analog Signal Generator

The NI PXI-5650 (Part Numbers: 779670-00, 191967C-01) is a 1.3 GHz Analog Signal Generator that has wave generation capacities that proceed with FM, 2-FSK, or OOK modulation. It utilizes direct digital synthesis (DDS) for high resolution frequency jumps or continuous phase sweeps for equipment or gadget characterization applications. The PXI-5650 is perfect for synchronization of non-standard examining rates, such as WCDMA signals in baseband or intermediate frequency (IF). With these adaptable signal generators, the user can perform analog and digital modulation through the inward DDS circuit, which gives frequency modulation and frequency offset for applications, such as bit error ratio tests, antenna tests, or even non-digital input key. The user can also perform modulation on the amplitude by utilizing on-off control.

The PXI-5650 shows how the framework control unit deals with the control signals and information exchanged between the circuit squares. The framework control unit contains the temperature screen and adjustment components, and it offers over 50 MHz. Signal generation happens inside the main synthesizer circuit, and it is phase-locked to the DDS output signal as a source of reference. The Generator offers a RF generator frequency range of 500 kHz to 1.3 GHz.

The clocking circuitry included with the PXI-5650 contains the framework clock reference and the DDS. This framework clock is a 200 MHz voltage-controlled crystal oscillator (VCXO) that the user can program to phase-lock to an outside 10 MHz clock signal at the REF IN/OUT connector. The DDS timed by the 200 MHz reference gives signs of up to 50 MHz, with fine recurrence steps. Any RF motions below 50 MHz come straight from the DDS.

In terms of software, the PXI-5650 Analog Signal Generator runs using the NI-RFSG driver. This software is compatible with application development environments (ADEs) like LabVIEW or LabWindows/CVI. It has a recommended warm-up time of the overall device is 30 minutes, and it is recommended to calibrate at least once a year.

The PXI-5650 signal generator weighs 14.6 oz, and measures 8.5 x 0.8 x 5.1 in. in physical dimensions. It has a recommended operating temperature range of 0 °C to 55 °C, a storage temperature range of -40 °C to 70 °C, and a noncondensing humidity range of 10% to 90% and 5% to 95% respectively.

While the PXI-5650 is no longer available from the manufacturer National Instruments, the PXI RF Analog Signal Generator will remain available in perpetuity from Apex Waves!
