National Instruments Extends PXI to Microwave Frequencies with New Signal Generators up to 6.6 GHz

  National Instruments today announced seven new signal generators for applications from DC to microwave – four for DC to high-frequency generation and three for RF and microwave frequencies. The new RF and microwave signal generators extend PXI to 6.6 GHz for continuous-wave (CW) sourcing, common tunable local oscillator (LO) and stimulus-response applications. In a single 3U PXI slot, the RF and microwave signal generators also offer the best phase noise and jitter of any NI source. In addition, the new arbitrary function generators have the highest analog output accuracy on the market for PXI and PCI. All seven generators use direct digital synthesis (DDS) for high-resolution frequency hopping or phase-continuous sweeping for characterization applications.

With the NI PXI-5652 6.6 GHz RF and microwave signal generator, the NI PXI-5651 3.3 GHz RF signal generator and the NI PXI-5650 1.3 GHz RF signal generator, engineers can easily set up sophisticated stimulus-response or tracking-generator applications using the NI PXI-5660 RF vector signal analyzer and the National Instruments LabVIEW graphical development environment. The new RF and microwave signal generators are also useful for continuous sinewave applications, including sweeping, as well as fixture and device characterization. They are ideal for clocking non-standard sample rates, such as WCDMA signals at baseband or intermediate frequency (IF). The versatile signal generators can perform analog and digital modulation through the onboard DDS circuit, which gives engineers frequency modulation (FM) and frequency-shift keying (FSK) for applications such as bit-error rate testing (BERT), antenna testing or even keyless entry. Amplitude modulation is also available through on-off keying (OOK).

The new NI 5406 40 MHz bandwidth and NI 5402 20 MHz bandwidth function generators for PCI and PXI can generate standard waveforms including sine, square and triangle waveforms. They also can generate repetitive arbitrary waveforms up to 16 KB in size for low-cost arbitrary waveform generation. They offer unparalleled analog performance and complex triggering, and can sweep from DC to 40 MHz with a .355 μHz frequency resolution. The function generators incorporate circuitry for sub-nanosecond module-to-module synchronization.

The signal generators are ideal for a variety of applications, including device characterization, telecommunications, military/aerospace and consumer electronics. They seamlessly combine with digitizers and digital waveform generator/analyzers for an integrated mixed-signal test solution. The new devices integrate with the NI LabVIEW graphical development environment, NI LabWindows/CVI for ANSI C development and NI TestStand test management software. The arbitrary function generators also work with NI SignalExpress interactive measurement software for design and test.

In August, NI will host the second annual RF and Wireless Communications Summit at NIWeek 2006. Jon Adams, vice chairman of the ZigBee Alliance and director of radio technology and strategy for Freescale Semiconductor, will give a presentation on ZigBee technology at the summit.
